The recycled domestic wastewater can be discharged to a urinal or can be taken out by itself, such as flower watering, mop washing and the like; preferably, the recycled water taking pool 202 can be the mop pool 103, the wastewater in the water taking pool can be recycled for a plurality of times, and a striking mark is made nearby, so that a user is prompted that the water taken by the faucet is recycled water.
If the domestic wastewater is simply filtered, only some impurities such as vegetable leaves and the like can be screened, but organic pollutants in the wastewater are not removed. The domestic waste water mainly comprises soap, grease, synthetic detergent, cleaning agent and a small amount of harmful substances such as bacteria, coliform bacteria, viruses and the like. Thus, the bad smell is deteriorated when the wastewater is stored for a long time, and the domestic wastewater is slightly bad when stored for a long time especially in hot summer.
Therefore, the invention adopts a biomembrane method to treat the wastewater, and the technology is to make the wastewater pass through a biomembrane formed by growth and propagation of aerobic microorganisms, protozoa, metazoan and the like on carrier fillers, adsorb and degrade organic matters, and purify the wastewater. Early biomembrane sewage treatment processes developed slowly, mainly because the biomembrane structures adopted in the earliest in production are trickling filters with broken stone as filler, but with the continuous development of the plastic industry, the process is also more and more important. The main process of treatment is that the wastewater is precipitated by a precipitation tank 21, filtered by a filter layer 22 and enters a biological membrane reactor 23, and organic matters are removed by aerobic biological oxidation in the biological membrane reactor 23. The biomembrane method can be mainly used for treating denitrification, removing heavy metals, microorganisms, macromolecular particles and other impurities. In the invention, the sewage inflow water is designed at the bottom of the tank, and the water flow is flushed, so that the effect of stirring suspended filler can be achieved, the installation of a stirrer is omitted, and an aeration tank is also avoided. The domestic wastewater is filtered and purified step by step, and can be stored for seven days in summer without stinking.
The waste water can be discharged after being purified and lifted to a certain height, and people feel annoyance if the water is pumped continuously every day. Therefore, the water level control module 51 is designed, and the water replenishing of the water storage tank 5 can be realized fully automatically. When the water level sensor detects that the water level is reduced to a preset low water level line, the water pump 3 is automatically controlled to start pumping water; when the water level sensor detects that the water level rises to a preset high water level line, the water pump 3 is automatically controlled to stop working.
Preferably, the recovery tank 2 is built in a pit reserved in the bathroom, and the water storage tank 5 is built in an interlayer of the wall of the bathroom so as to avoid occupying living space. It will be appreciated that the pit is reserved in the bathroom before the house is handed over, the invention uses the position to construct the recovery pool 2, the space of the house is not occupied, and the water pump and various pipelines can be arranged in the interlayer of the underground or the wall. In addition, the top ends of the recovery tank 2 and the water storage tank 5 and the floors and walls at corresponding positions can be provided with door structures capable of being opened and closed, so that users can clean the inside of the water storage tank, and if faults occur, the water storage tank is convenient for staff to process.
Preferably, a water outlet communicated with the sewer pipe is further formed in the top end of the sedimentation tank 21 so as to discharge excessive domestic wastewater in the sedimentation tank 21.
With further reference to fig. 2, a water inlet controller is provided in the tank 10 of the urinal 201; the water inlet controller comprises a first control pipe and a second control pipe which are arranged along the vertical direction, wherein a first pontoon 11 is arranged in the first control pipe, a second pontoon 12 is arranged in the second control pipe, and the cross section sizes of the first pontoon 11 and the second pontoon 12 are respectively matched with the inner cross section sizes of the first control pipe and the second control pipe and are tightly matched with each other, so that the first pontoon 11 and the second pontoon 12 can respectively slide in the first control pipe and the second control pipe under the action of buoyancy; a fixed pulley 18 is fixedly arranged at the boundary of the bottom ends of the first control tube and the second control tube, the bottom ends of the first pontoon 11 and the second pontoon 12 are connected through a traction rope 17, and the traction rope 17 is wound in a pulley groove of the fixed pulley 18; the side of the first control pipe is provided with a reclaimed water inlet 13 communicated with the water conveying pipeline 6, the side of the second control pipe is provided with a tap water inlet 14 communicated with a tap water pipeline, the reclaimed water inlet 13 is higher than the tap water inlet 14, the volume of the first pontoon 11 is larger than that of the second pontoon 12, so that when water in the water tank 10 is enough, the reclaimed water inlet 13 can be blocked by the first pontoon 11, and meanwhile, the tap water inlet 14 can be blocked by the second pontoon 12. Preferably, the first control pipe has an inner diameter twice that of the second control pipe, while the first pontoon 11 has a diameter twice that of the second pontoon 12, and the reclaimed water inlet 13 has a diameter twice that of the tap water inlet 14, so as to achieve the purpose of preferential entry of reclaimed water into the water tank 10. The water tank 10 further includes a flush valve 15 and a flush port 16, and the structures of the flush valve 15 and the flush port 16 are not limited thereto, as long as they are conventional.
It will be appreciated that when there is sufficient water in the tank 10, the first pontoon 11 is subjected to a greater buoyancy and the position of the second pontoon 12 is restricted by the traction rope 17 to block the two inlets respectively; when the user operates the flushing switch 15 to start flushing, the water level in the water tank 10 drops, the first pontoon 11 drops first to open the recovery water inlet 13, so that the recovery water can be used for flushing, and the second pontoon 12 rises by a distance corresponding to the first pontoon; if the recovered water is insufficient, the water level in the water tank 10 further drops, and the second pontoon 12 further rises to open the tap water inlet 14; after the flushing is finished, the first pontoon 11 pulls the second pontoon 12 to block the corresponding water inlet along with the rising of the water level, and the cycle is repeated. In addition, the upper end and the lower end of the first control tube and the second control tube can be provided with limiting structures so as to limit the movement range of the first pontoon 11 and the second pontoon 12.
In conclusion, the automatic recycling system for biological purification of the residential domestic wastewater can fully recycle the domestic wastewater, save water resources, reduce water cost, lighten the economic burden of residents and does not occupy space; in addition, the recovery tank is provided with a related structure for purifying the wastewater, so that the wastewater is prevented from being smelly, the quality of the recovered water is improved, the purification effect is good, and the cost is low; related structures are designed in the water storage tank to realize automatic water supplementing; related structures are designed in the water tank of the urinal so as to realize automatic switching of the reclaimed water and tap water.
