Description

One way of life wastewater efficient treatment system
Technical field
The present invention relates to the one way of life Sewage treatment systems, specifically a kind ofly utilize the microbiological treatment sanitary sewage and make efficient, the harmless treatment system for the treatment of processes.
Background technology
Present stage, China's domestic sewage processing method almost was single product entirely, namely just was processed into middle water and mud discharging, do not touch comprehensive utilization, generally, comprised that the sewage disposal overall efficiency of energy expenditure is very low.And wherein mud is the mixture of a large amount of harmful organic substances, poisonous substance, inorganic body refuse etc., not only needs the space to stack, transport and process, but also can cause secondary pollution.In addition, the gas generation process of existing treatment process also can cause atmospheric pollution simultaneously.The random discharging of Urban Residential District, rural area village, village sanitary sewage has caused contaminate environment on the one hand, also is a kind of wasting of resources on the other hand.And current domestic sewage processing method can not be realized both non-secondary pollutions, nontoxic, has again very high process efficiency.In fact, except available middle water, also have mud, sand, the dregs form materials such as rich nutritive material, mineral substance such as a large amount of organism in the sewage that discharges.If through processing such as biochemical reaction, separation, precipitations, can reclaim with biogas, Zhong Shui, fertilizer form fully, form the recycle process of resource.Therefore, be necessary to research and develop a kind of sanitary sewage total system that turns bane into boon, turns waste into wealth, fundamentally improve overall efficiency and the cyclic utilization rate of sewage disposal.
Summary of the invention
For reducing secondary pollution and the wasting of resources of sewage disposal, form recycle and the efficient process of water resources, the invention provides one way of life wastewater efficient treatment system, it is the anaerobic pond in the sanitary sewage flow process efficiently to be moved with versatility design.Anaerobic pond is reprinted sink pond, return line, water inlet pipe of conveyer, warmer water inlet pipe, mud pump drainage mouth, mud by reaction chamber, biogas pipe, seal closure, rising pipe, pond temperature sensor, temperature signal line, warmer return water pipe, warmer pipe row array plate, chain-belt type by product and is formed.In top, space between the partition wall bottom of the bottom surface, pond of anaerobic pond and seal closure and the pond left side wall and the space between the seal closure left side wall of anaerobic pond, be equiped with the chain-belt type by product and reprint conveyer, body is by reprinting follow-up pulley, conveyer chain band, conveyer chain holder guide wheel, transmit BOGEY WHEEL, turning to holder guide wheel, reprinting motion-work wheel and reprinting to turn to BOGEY WHEEL to consist of.
The technical solution adopted for the present invention to solve the technical problems is:
Design efficiently moving in the sanitary sewage technical process with versatility:
The main technique system that adopts by settling bowl, anaerobic pond, concentration basin, aerobic pond and by aeration, turn press pump, concentration basin, solid-liquid separator, lift pump high tower sterilization pool, user, solar water heater, gas fired-boiler, control station, gas-holder and consist of.Wherein anaerobic pond is reprinted sink pond, return line, water inlet pipe of conveyer, warmer water inlet pipe, mud pump drainage mouth, mud by reaction chamber, biogas pipe, seal closure, rising pipe, pond temperature sensor, temperature signal line, warmer return water pipe, warmer pipe row array plate, chain-belt type by product and is formed.
In top, space between the partition wall bottom of the bottom surface, pond of anaerobic pond and seal closure and the pond left side wall and the space between the seal closure left side wall of anaerobic pond, be equiped with the chain-belt type by product and reprint conveyer, body is by reprinting follow-up pulley, conveyer chain band, conveyer chain holder guide wheel, transmit BOGEY WHEEL, turning to holder guide wheel, reprinting motion-work wheel and reprinting to turn to BOGEY WHEEL to consist of.
The temperature controlling system at temperature control station is gentle by comparing element, control, amplification, driving link, hydraulic servo is carried out link and consisted of.
The temperature of anaerobic pond bottom space detects by the pond temperature sensor, with the comparing element of pond temperature signal feedback to temperature-control device.In the comparing element of temperature-control device, the pond temperature signal of feedback compares with the given signal of pond temperature that (such as corresponding 35 ℃) are set on demand, produces pond temperature deviation signal.Pond temperature deviation signal enters control, amplification, drives link, participates in control and amplification, drives and process.
