The application belongs to the technical field of sewage treatment, and particularly relates to a continuous water supply and intermittent drainage device for a sewage treatment biological bed.
Background
With the improvement of urban level and the rapid expansion of population scale, the urban sewage treatment requirements are also higher and higher, wherein one of the important indexes of urban sewage treatment is whether the COD value reaches the standard. In the prior art, the main process flow of sewage treatment is as follows: firstly, solid-liquid separation (sedimentation tank) is carried out on sewage, and then, COD value is reduced through certain biochemical treatment (aeration treatment for aerobic fermentation) so as to realize standard discharge. One of the main disadvantages of this approach is that the sewage treatment plant needs to occupy a large area of land, and the sewage treatment speed is slow, which makes it difficult to meet the actual sewage treatment requirements.
In combination with the existing sewage treatment process, a series of new sewage treatment devices and processes are developed and designed in the prior art to meet the technical requirements of low energy consumption, low cost, low occupation of land and the like, for example: a three-ditch oxidation ditch method, an SBR method, a UNITANK technology, a Biological Aerated Filter (BAF), a Membrane Bioreactor (MBR) and a series of novel high-efficiency sewage treatment technologies. However, in general, the existing treatment processes or devices still have certain disadvantages of low treatment speed, high treatment cost and the like, and due to the huge sewage throughput, further development and design of the sewage treatment device are still necessary to better meet the actual sewage treatment needs.

the lever seal capable of swinging up and down along the side wall of the upper water tank is arranged on the side wall of the middle part of the upper water tank close to the water tank body;
the lever seal is characterized in that one end of the lever is provided with a lower sealing valve, the lower sealing valve faces to the water outlet of the water tank body, and the lower sealing valve seals the water outlet under the action of gravity in the initial stage of sewage water inlet; the other end of the lever is provided with an upper sealing valve for sealing an upper water outlet at the bottom of the upper water tank; in the running process, the opening or closing of the water tank body water outlet (quantitative intermittent water discharge) is realized through the up-and-down swing of the lever seal;
in order to realize the quantitative intermittent drainage function of mechanical automation, the bottom of the water tank body close to the water outlet is provided with a lower floating groove, the bottom of the lower floating groove is provided with a lower water outlet, meanwhile, the lower floating groove body is internally provided with a lower floating valve capable of sealing the lower water outlet, and the lower floating valve is fixedly connected to a lever of the lever seal;

It should be noted that in the general design, the height of the bottom plate of the upper water tank is higher than that of the top surface of the lower float bath, so that the implementation of the related automation function can be ensured.
The specific operation process (namely, the process of realizing the continuous water supply and intermittent water discharge function) is as follows:
under the action of gravity, the lower sealing valve at one end of the lever is in a sealing state to the water outlet when the water pump is not in use; in the sewage treatment process, sewage continuously enters from an upper water tank at one side far away from an upper water outlet in an upper water tank, and overflows through an upper water tank floating tank in sequence (an upper floating valve in the upper water tank floating tank floats upwards under the buoyancy action of a water body at the moment, and meanwhile, a lower sealing valve at the other end of a lever can be used for better sealing a water outlet), so that the upper water outlet enters the inside of a tank body of the water tank body;
with the increase of the water quantity and the rise of the liquid level in the water tank body, part of water overflows into the lower floating tank, under the action of the buoyancy of the water body, the lower floating valve floats upwards to drive the change of the lever moment and finally drive the opening of the lower sealing valve, on the other hand, under the drive of the floating action of the lower floating valve, the upper sealing valve can immediately seal the upper water outlet, the upper floating valve also sinks to seal the upper water outlet (the sewage entering the upper water tank still continuously flows in at the moment because of the short follow-up emptying time), and the instant discharge of the sewage in the water tank through the water outlet can be ensured at the moment;
the lower floating valve floats upwards, so that the lower drain hole at the bottom of the lower floating tank is opened, water in the lower floating tank is gradually discharged, after the buoyancy effect is lost, the lower floating valve is reset, the lower sealing valve also reseals the drain hole, the upper floating valve and the upper sealing valve simultaneously open the corresponding upper drain hole and the upper water outlet, sewage in the upper water tank reenters the water tank body, and a new sewage treatment cycle is started.
In the running process, the water outlet is intermittently opened, so that intermittent water drainage is realized, and meanwhile, under the condition that the sewage inflow speed is fixed, the opening time of the water outlet is relatively fixed, so that quantitative water drainage is realized; in the related drainage process, sewage can continuously enter, so that the continuous water supply (uninterrupted water supply) function can be realized.
It should be explained and explained that in the existing biological bed sewage treatment process, when sewage to be treated is input into the biological bed, the design is generally an intermittent water supply design which depends on electronic control, namely, the water pump is quantitatively started at regular intervals, so that the sewage to be treated is input into the biological bed. Because the general water pump needs frequent start in the water supply process, the stability requirement on relevant electronic devices is higher, and the electronic devices are extremely easy to age and the like along with the extension of the running time, so that the stable operation of the treatment of the biological bed is influenced, meanwhile, the frequent start of the water pump is easy to cause the overhigh loss of equipment, and the service life of the equipment is reduced. The sewage treatment biological bed that this application provided is with continuous water supply, intermittent drainage device mainly is with biological bed (ecological bed) supporting use in the sewage treatment process, promptly: by the continuous water supply and quantitative intermittent drainage device, intermittent and quantitative input of sewage inflow to be treated of the biological bed can be realized, so that continuous and automatic operation of the biological bed is promoted. And further overcomes the defects of easy aging of electronic devices, high water pump loss and the like caused by intermittent water inflow when the control of an electric device is relied on in the water inflow stage in the existing biological bed sewage treatment process.
In general, the sewage treatment biological bed provided by the application is with continuous water supply, intermittent drainage device, its structural design is ingenious, through relevant mechanical structure design optimization, can realize automatic intermittent drainage, can ensure continuous water supply simultaneously, except that the sewage that intakes adopts the power pump to go into, the opening of whole device is closed to rely on mechanical automation to realize to reduce the harm to frequent start of electric power device, need not more manpower intervention in the operation process moreover, and then ensure follow-up biological bed sewage treatment's steady operation. The device provided by the application has the advantages of reduced maintenance cost, and good practical value for promoting the progress of sewage treatment technology, so that the device has good popularization and application significance.

Examples
As shown in fig. 1, the continuous water supply and intermittent water discharge device for the sewage treatment biological bed provided by the application has the specific structure that:
a water tank body with an opening at the top, which is formed by surrounding the edge of the water tank body, and a water outlet 12 is arranged at the bottom of the water tank body and used for discharging sewage; an upper water tank 4 is fixed above the middle part inside the water tank body, and an upper water outlet 6 is arranged at the bottom of the water tank body;
the lever seal 13 which can swing up and down along the side wall of the upper water tank is arranged on the side wall of the middle part of the upper water tank close to the water tank body.
The lever seal is characterized in that one end of the lever is provided with a lower sealing valve (not labeled in the figure), the lower sealing valve is opposite to the water tank outlet 12, and the lower sealing valve seals the water outlet under the action of gravity in the initial stage of sewage water inflow; the other end of the lever is provided with an upper sealing valve 3 for sealing an upper water outlet 6 at the bottom of the upper water tank; in the running process, the opening or closing of the water tank outlet 12 (quantitative intermittent drainage) is realized through the up-and-down swing of the lever seal 13;
in order to realize the quantitative intermittent drainage function of mechanical automation, the bottom of the water tank body close to the water outlet is provided with a lower floating groove 9, the bottom of the lower floating groove 9 is provided with a lower water outlet 10, and meanwhile, the lower floating groove body is internally provided with a lower floating valve 11 capable of sealing a lower water outlet, and the lower floating valve 11 is fixedly connected to a lever of the lever seal.
In order to better adjust the buoyancy of the lower float valve 11 in the intermittent drainage process, in the preferred design, the middle part of the upper water tank body is provided with an upper water tank float tank 2, the upper water tank float tank 2 divides a water inlet (not marked in the figure) into an upper water tank 1, the bottom of the upper water tank float tank 2 is provided with an upper water drain port 7, an upper float valve 8 capable of sealing the upper water drain port 7 is arranged in the upper water tank float tank 2, and the upper float valve 8 is fixedly connected to a lever.
When the device runs specifically, the device is matched with a power device (such as a water pump, the water inlet flow is required to be kept stable) which can keep the water inlet flow stable; before use, the lower sealing valve at one end of the lever seals the water outlet 12 under the action of gravity.
During sewage treatment, sewage continuously enters from the upper water tank 1 at one side, far away from the upper water outlet 6, in the upper water tank 4 and sequentially overflows through the upper water tank floating tank 2 (an upper floating valve 8 in the upper water tank floating tank 2 floats upwards under the buoyancy of a water body at the moment, on one hand, an upper water drain port 7 is opened, and meanwhile, a lower sealing valve at the other end of a lever can be used for better sealing a water drain port 12), and the upper water outlet 6 enters the water tank body 5;
as the amount of sewage entering the water tank body inside 5 increases and the liquid level rises, part of sewage overflows into the lower floating groove 9, the lower floating valve 11 floats upwards under the action of the buoyancy of the water body, so as to drive the change of lever moment and finally drive the lifting of the lower sealing valve and the opening of the water outlet 12; on the other hand, under the driving of the floating force of the lower floating valve 11, the upper sealing valve 3 will also seal the upper water outlet 6 immediately, and the upper floating valve 8 will sink to close the upper water drain 7 (the sewage entering the upper water tank 1 can still flow continuously at this time due to the short draining time during the subsequent intermittent draining), so that the sewage after being treated in the water tank 5 can be discharged through the water drain 12 quickly.
Due to the floating action of the lower floating valve 11, the lower drain port 10 at the bottom of the lower floating tank 9 is opened at the same time, water in the lower floating tank 9 is gradually discharged, after the floating action is lost, the lower floating valve 11 is reset, the lower sealing valve reseals the drain port 12, the upper floating valve 8 and the upper sealing valve 3 simultaneously open the corresponding upper drain port 7 and the upper water outlet 6, sewage in the upper water tank 1 reenters the water tank body 5, and a new sewage inflow cycle is started.
In the running process, the water outlet 12 is intermittently opened, so that intermittent water discharge is realized, and meanwhile, under the condition that the sewage inflow speed is fixed, the opening time of the water outlet 12 is relatively fixed, so that quantitative water discharge is realized; in the related drainage process, sewage can continuously enter, so that the purpose of continuous water supply (uninterrupted water supply) can be achieved.
When the continuous water supply and intermittent drainage device for the sewage treatment biological bed is specifically applied, the continuous water supply and intermittent drainage device is mainly matched with the biological bed (ecological bed) in the existing sewage treatment process, namely: by the continuous water supply and quantitative intermittent drainage device, intermittent and quantitative input of sewage inflow to be treated of the biological bed can be realized, so that continuous and automatic operation of the biological bed is promoted. But in the practical application process, the device can also be independently used as a biological bed (ecological bed), so that the continuous treatment of sewage can be realized, and the sewage treatment time in the box body is prolonged due to the intermittent drainage design, so that the sewage treatment effect is further improved.
