Description
Technical Field
The invention belongs to the related field of sewage treatment equipment, and particularly relates to a rural domestic sewage integrated treatment system.
Background
Along with the development and frequent communication of rural economy, the living standard of rural residents is improved, so that the rural domestic sewage is increased invisibly. Rural domestic sewage mainly comprises washing, bathing and kitchen drainage, rural public facilities, domestic agricultural and sideline product processing and other drainage, generally contains higher-concentration organic matters, nitrogen and phosphorus, in rural areas, sewage treatment scale is small, rural residences are dispersed, the problems of dispersed discharge, difficulty in large-scale centralized treatment, low treatment efficiency, high energy consumption and the like exist, at present, a plurality of rural sewage collecting pipe networks and sewage treatment infrastructures are seriously lagged in construction, sewage directly flows to a lower place along the terrain or is discharged into peripheral water bodies without being treated, and the health of the masses is seriously affected and damaged, so that the rural sewage treatment is suitable for adopting unattended sewage treatment integrated devices and systems for treating small-scale domestic sewage.
The existing rural distributed sewage treatment devices are various in types, and the utilized treatment processes and methods are various in principle, and mainly comprise an artificial wetland method, an aerobic activated sludge method, a biological membrane technical method and the like. In the process of practical application, the sewage treatment device and the sewage treatment system formed based on the method and the process have a plurality of defects. For example: although the artificial wetland is a natural ecosystem treatment method, the artificial wetland has large floor area, high investment and unsatisfactory water outlet effect; in the aerobic activated sludge method, the activated sludge is easy to have abnormity, such as expansion or disintegration, and needs to be attended manually to deal with the abnormal condition of the sludge, so the maintenance is complex and the operation cost is high; some sewage treatment equipment is transformed from traditional process equipment, but the integration level is not high, the treatment effect is not good, the power consumption is high, and the economic and environmental benefits are low; some sewage treatment devices adopt a biomembrane technology method, the effluent quality is more stable, but the maintenance is troublesome and the energy consumption is high.
Therefore, aiming at the characteristics of rural sewage and the defects of large occupied area, poor treatment effect, high energy consumption and high operating cost in the prior art, the integrated efficient treatment device and system for rural domestic sewage, which can be unattended, efficient, energy-saving and stable in water outlet effect, needs to be developed urgently.
Disclosure of Invention
The invention aims to provide a rural domestic sewage integrated treatment system aiming at the defects in the prior art.
In order to realize the invention, the following technical scheme is adopted: the rural domestic sewage integrated treatment system comprises an oil separation grit chamber and a purification tank, wherein the oil separation grit chamber is connected with the purification tank; an anaerobic zone, an anoxic zone, an aerobic zone, a sedimentation zone and a disinfection zone are arranged in the purification tank, and the anaerobic zone, the anoxic zone, the aerobic zone, the sedimentation zone and the disinfection zone are communicated in sequence; anaerobic fillers are arranged in the anaerobic zone, anoxic fillers are arranged in the anoxic zone, and biological fillers are arranged in the aerobic zone; an aeration device is arranged at the bottom of the anaerobic zone, a fan is arranged outside the anoxic zone and is connected into the anoxic zone through an air pipe, and an oxygen conveyor is arranged outside the aerobic zone and is connected into the aerobic zone through an oxygen pipe.
Preferably, the anaerobic filler in the anaerobic zone is specifically phosphorus accumulating bacteria.
Preferably, the anoxic filler in the anoxic zone is a porous gel carrier filler or a spherical carrier filler or a honeycomb PE carrier filler.
Preferably, the biological filler in the aerobic zone is aerobic bacteria.
Preferably, the outer side of the cleaning and disinfecting area is provided with a soda ash feeding device and a sodium hypochlorite feeding device, and the soda ash feeding device and the sodium hypochlorite feeding device are respectively connected with the disinfecting area.
Preferably, the purification tank is further provided with a plc controller outside, which controls the start of the fan, the aeration interval time of the aeration device, the delivery capacity of the oxygen conveyer, the feeding capacity of the soda ash feeding device and the sodium hypochlorite feeding device.
When the oil separation grit chamber works, suspended matters in the sewage are separated from the water by utilizing the gravity action principle, and the suspended matters are removed to purify the sewage. The suspended matter is settled when the specific gravity is larger than that of the sewage and floats up when the specific gravity is smaller than that of the sewage.
When the anaerobic zone works, macromolecular substances are degraded in an anaerobic environment to reduce the concentration of organic matters, the activated sludge enters the sedimentation tank synchronously, phosphorus-accumulating bacteria release phosphorus in the anaerobic environment, COD (chemical oxygen demand) and VFA (vacuum fast oxygen demand) which are easy to degrade are converted into PHB, and part of nitrogenous organic matters are oxidized.
When the anoxic zone works, the reactor has the primary functions of denitrification, nitrate nitrogen is transmitted from the aerobic reaction zone through the internal circulation of mixed liquor, partial organic matters are degraded and removed by using nitrate as an electron acceptor under the action of denitrifying bacteria, and spherical fillers are filled in the anoxic tank.
When the aerobic zone works, the effluent of the anoxic tank automatically flows to the aerobic tank for biochemical treatment, most organic matters in the sewage are degraded and purified, the aerobic bacteria take the filler as a carrier, and the organic matters in the sewage are used as foodstuff to decompose the organic matters in the sewage into inorganic salts, and meanwhile, the nitrification of ammonia nitrogen and the absorption of phosphorus are realized, thereby achieving the purification purpose. The nitrate nitrogen in the mixed liquid flows back to the facultative tank, and the phosphorus excessively absorbed in the sludge is discharged through the residual sludge. The aerobic bacteria must have enough oxygen, namely enough dissolved oxygen in the sewage, so as to achieve the purpose of biochemical treatment.
When the sedimentation works, sewage flows into the sedimentation tank through the aerobic tank, suspended matters are further settled and removed, and when the sewage containing the suspended matters flows from bottom to top, the suspended matters are settled under the action of gravity. The lower part is provided with a conical settling zone, and the sludge is conveyed to the anaerobic tank in a backflow mode.
Has the advantages that: (1) compared with a large-scale traditional sewage treatment system, the device has the advantages of small occupied area, low investment, low energy consumption, convenient maintenance and good sewage treatment effect, is suitable for single-family or multi-family rural families, and promotes the popularization and use of the rural domestic sewage integrated treatment method and technology in rural areas.
