Abstract
The invention discloses a district sanitary sewage treatment system including a hydraulic sieve, a regulation pool, an aeration biological filter tank, a quartz sand filter tank and a clean water tank, the district sanitary sewage treatment system can effectively remove organic matters, ammonia nitrogen and suspended solids in wastewater, and the treated effluent is disinfected for reuse for greening and flushing toilets. Equipment used in the district sanitary sewage treatment system is corrosion resistant in materials, long in service life, and basically free of maintenance in the latter use.
Description
Technical field
The invention belongs to sewage treatment area, particularly a kind of community domestic wastewater treatment system.
Background technology
Water resources in china occupancy volume per person is only world occupancy volume per person's 1/4, in state-owned more than 400 lack of water cities, wherein there is serious water shortage problem in more than 100 city.Shortage of water resources and water pollutions aggravation currently affect one of principal element of China's Sustainable development.In recent years, whole world environment specialist actively advocates the dispersion treatment mode of sewage treatment in situ, community life sewage treatment in situ, and effluent reuse is afforested, flushed the toilet, and not only can reduce total amount of sewage discharge, can realize water cycle, saving water resource simultaneously.
Current community domestic wastewater treatment adopts biological contact oxidation process and membrane bioreactor mostly.Although these two kinds of methods are applied, equal Shortcomings in actual moving process.Such as: biological contact oxidation process in During Process of Long-term Operation, due to filler block gradually, aging, support corrodes, and replacing filler shut down by every 1 ~ 3 year needss, and support does anticorrosion again, and later maintenance cost is high; Membrane bioreactor membrane module used is expensive, needs within every 1 ~ 3 year, change once, early investment and later maintenance cost high, most of user cannot accept.
Summary of the invention
The problems such as the object of this invention is to provide a kind of community domestic wastewater treatment system, can solve the equipment and materials corrosion and ageing existed in existing community domestic wastewater treatment process, work-ing life is short, and later maintenance working cost is high.
In order to solve the problem, technical scheme of the present invention is as follows:
Embodiment of the present invention provides a kind of community domestic wastewater treatment system, comprises hydraulic screen, equalizing tank, aerating biological filtering pot, quartz sand filtration tank and clean water basin.
Above-mentioned hydraulic screen all adopts corrosion resistant stainless material to make.
Above-mentioned equalizing tank and clean water basin adopt Reinforced Concrete Structure pond or glass reinforced plastic assembled water tank or stainless steel assembled water tank, more than 30 years work-ing life.
Glass reinforced plastic winding tank all selected by above-mentioned aerating biological filtering pot and quartz sand filtration tank, more than 30 years work-ing life.
Further, filling volcanic rock biological filter material in above-mentioned aerating biological filtering pot, utilizes organism, ammonia nitrogen and the suspended substance in the microbial film of apposition growth on volcanics filtrate and the active sludge removal sewage of suspension.
Further, above-mentioned volcanic rock biological filter material intensity is high, once drops into, and need not change throughout one's life.
Further, above-mentioned quartz sand filtration tank is in-built fills out quartz sand filter media, carries out depth type filtration, remove Organic substance in water, ammonia nitrogen and suspended substance further to aerating biological filtering pot water outlet.
As can be seen from the above-mentioned technical scheme provided, the Sewage treatment systems that the invention process provides, effectively can remove organism, ammonia nitrogen and the suspended substance in sewage, and water outlet reuse can be afforested and flush the toilet after sterilization.Meanwhile, the equipment and materials that the method treatment system adopts is corrosion-resistant, and long service life is substantially non-maintaining in later stage use procedure.
Accompanying drawing explanation
Accompanying drawing is the schematic flow sheet for the treatment of process of the present invention.
Wherein: 1, hydraulic screen 2, equalizing tank 3, inlet water lifting pumps 4, oxygen supply air pump 5, aerating biological filtering pot 6, vent valve 7, biofilter material 8, quartz sand filtration tank 9, backwash pump 10, clean water basin 11, back flushing water outlet
Embodiment
The present invention is described in detail to tie figure the drawings and specific embodiments below.
As shown in the figure, a kind of schema of community domestic wastewater treatment method, the method is that community life sewage is first carried out solid-liquid separation by hydraulic screen 1, sewage after separation flows into equalizing tank 2, then by inlet water lifting pumps 3, sewage in equalizing tank is sent in water aerating biological filtering pot 5, air is sent in aerating biological filtering pot 5 by logical oxygen supply air pump 4 simultaneously, air and sewage together upwards flow through the biological filter bed of material 7, tail gas is by the outer row of the vent valve 6 at aerating biological filtering pot top, water outlet enters quartz sand filtration tank 8, quartz sand filtration tank 8 water outlet enters clean water basin 10, reuse after sterilization, every 1,2 day backwash pump 9 pairs of aerating biological filtering pots 5 and quartz sand filtration tank 8 carry out a back flushing, and back flushing water outlet 11 enters neighbouring septic tank.
Above-described embodiment, just in order to technical conceive of the present invention and feature are described, its objective is and is one of ordinary skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.The change of every equivalence done by the essence of content of the present invention or modification, all should be encompassed in protection scope of the present invention.
