Detailed Description

The utility model is described in further detail below with reference to the figures and the specific embodiments.

As shown in fig. 1, 2, 3, 4 and 5, the integrated water purifier for a river channel of the present invention comprises a steel-concrete water storage biochemical tank 1 connected to a river through a pump, and further comprises a water purifier main body 2 communicated with the steel-concrete water storage biochemical tank 1, wherein a static pipeline mixer 3 is further disposed at a water inlet of the water purifier main body 2, the water purifier main body 2 comprises a coagulation tank 4, a sedimentation tank 5 and a filtration tank 6 which are sequentially communicated, two hyperboloid mixers 7 are disposed in the coagulation tank 4, two layers of inclined plates 8 are disposed in the sedimentation tank 5, an inclined direction of the inclined plates 8 is upward along a water flow direction, a middle portion of the filtration tank 6 is quartz sand 9, a bottom portion thereof is a water distribution pipe 10, and the water distribution pipe 10 is communicated with a water outlet of the water purifier main body 2.

In addition, as shown in fig. 1, a clear water tank 11 is connected to a water outlet of the water purifier main body 2, a sludge discharge hopper is arranged at the bottom of the sedimentation tank 5 in the water purifier main body 2, a sludge storage tank 12 is connected to an opening at the bottom of the sludge discharge hopper, a sludge dewatering device 13 is connected to the sludge storage tank 12, a collecting tank 14 is connected to the sludge dewatering device 13, the collecting tank 14 is communicated with a water inlet of the water purifier main body 2, a backflushing device is arranged in the filtering tank 6, and a water outlet of the backflushing device is communicated with the collecting tank 14.

When this embodiment uses, river water gets into steel-concrete retaining biochemical pond 1 through the pump promotion, reuses the water pump promotion and gets into water purifier main part 2. In addition, the water treatment agent polyaluminium chloride is prepared in the dosing device in the dosing room respectively and is sent to the static pipeline mixer 3 by the metering pump, and the static pipeline mixer 3 is uniformly mixed by the shearing and stirring functions of the structure of the static pipeline mixer 3 and then enters the water purifier main body 2.

Raw water firstly enters the bottom of the water purifier main body 2 after entering the water purifier main body 2 to be distributed uniformly, the water flow speed is reduced, the raw water slowly enters the coagulation tank 4 to be coagulated, sewage flows upwards along the inclination direction of the inclined plate 8 under the flow guiding action of the inclined plate 8 and enters the sedimentation tank 5, deposited sludge slides downwards along the inclination direction of the inclined plate 8 under the action of gravity, meanwhile, the sliding alum flocs are pushed into the sludge discharge hopper under the hydraulic action of the inclined plate 8, water clarified by the inclined plate 8 enters the filtering tank 6 from the upper part of the water purifier main body 2 and is filtered by the quartz sand 9 from top to bottom, and the alum flocs in the water are intercepted and filtered by the quartz sand 9. The filtered clean water is collected to the clean water area at the bottom of the water purifier main body 2 through the filter head and returns to the clean water layer at the top of the water purifier main body 2 through the water distribution pipe 10. The raw water is purified in the water purifier main body 2 and then flows into the clean water tank 11 or is discharged to a river.

Wherein, the coagulation tank 4: raw water added with coagulant enters the coagulation tank through a water inlet pipe and is stirred by a hyperboloid stirrer 7, so that suspended matters in the water and the coagulant are fully contacted and reacted to form alum floc. In general, a water purifier mixes water and a coagulant by using a vortex reaction, but the effect is unstable due to a change in the amount of water, and the water purifier body 2 is mixed by a hyperboloid mixer 7 so that the effect is not affected by the change in the amount of water.

And (5) a sedimentation tank: the water is coagulated by adding coagulant to form alum floc, the alum floc flows into a sedimentation tank 5 of the equipment for sedimentation, the sedimentation tank 5 adopts an inclined tube sedimentation method, solid-liquid separation is completed by sedimentation in a sedimentation tank 5 with a trapezoidal inclined plate 8, and the settled sludge is discharged into a sludge discharge hopper.

And (6) a filtering tank: the water after precipitation flows into a filter tank 6 for filtration, the structure of the filter tank 6 is that the bottom is a water distribution pipe 10, the middle is quartz sand 9, the filtration speed is 10m/h, and finally the clean water flows into a clean water tank 11 for disinfection treatment. The backflushing period of the filter tank 6 is about 6-12 hours, and the backflushing time is 5-10 minutes.

Finally, the sludge in the sludge storage tank 12 is treated by a sludge dewatering device 13, the sludge cake is transported outwards, and the filtrate returns to the collecting tank 14.

When the embodiment is designed, an effective treatment process is formulated according to the characteristics of river water, so that the aim of purifying the water quality is fulfilled; due to the limitation of economic conditions in underdeveloped areas, the economic bearing capacity is weak, and a process with lower construction and operation cost is selected; due to the fact that maintenance management technicians and operation management experience are seriously poor, a process which is easy to manage needs to be selected.
