Abstract

The utility model discloses a municipal wastewater recycling system which comprises a wastewater and excrement filtering and sorting pool and a wastewater purifying pool, wherein a liquid dung inlet and a water overflow hole are respectively formed in the left side and the right side of the wastewater and excrement filtering and sorting pool, a flotage isolating device and an impurity filtering screen are vertically arranged at the left side in the wastewater and excrement filtering and sorting pool from top to bottom, an excrement filtering screen is aslant arranged at the right side of the wastewater and excrement filtering and sorting pool, and an excrement extracting pipe inlet is formed in the bottom of the middle part of the wastewater and excrement filtering and sorting pool. According to the municipal wastewater recycling system, liquid dung is classified so that flotage and impurities are firstly filtered out and then excrement is conveyed to a biogas digester; and meanwhile, wastewater and excrement are separated by adopting the filtering screen, and the wastewater is conveyed to a user or a farmland storage pool after being effectively treated. The excrement is conveyed to a biogas harmless treatment plant under the pressure to generate gas and fertilizer; and biogas residue and biogas slurry are deeply processed; for example, the biogas residue and biogas slurry are used for preparing organic compound fertilizers.

Description

City domestic sewage cyclic utilization system
Technical field
The utility model relates to a kind of Sewage treatment systems.
Background technology
Current city domestic sewage major part is to process through sewage work, and the municipal effluent that has small part is to be directly discharged in sewage river, causes serious environmental pollution.In the sewage that sewage work processes, some is from resident toilet ight soil water, and this water comprises the easy materials that produce biogas such as ight soil, directly carries out sewage disposal, not only greatly increase the difficulty of sewage disposal, can not make full use of this part material and remove to produce biogas.
Utility model content
The purpose of this utility model is to provide a kind of city domestic sewage cyclic utilization system, makes full use of resource, reduces the pressure that existing city domestic sewage is processed.
The technical solution of the utility model is:
City domestic sewage cyclic utilization system, comprise sewage ight soil filtering classification pond and the dirty water decontamination handles pond, the left and right sides, described sewage ight soil filtering classification pond is respectively equipped with liquid dung entrance and spillway, in described sewage ight soil filtering classification pond, left side is vertically provided with floating matter disrupter and foreign material filter screen from top to bottom successively, the right side in sewage ight soil filtering classification pond tilts to be provided with sieve for feces net, and the bottom in mid-way, sewage ight soil filtering classification pond is provided with ight soil and extracts entrance; Described spillway is communicated with the dirty water decontamination handles pond, right side, described sewage ight soil filtering classification pond is also provided with variable valve, described variable valve is connected with waste water transhipment pump by pipeline, and described waste water transhipment pump is connected with the dirty water decontamination handles pond, and the lower end of sieve for feces net is lower than variable valve position.
Also comprise methane-generating pit, feces cleaning and transporting vehicle or ight soil sludge pump, ight soil extracts entrance and is connected with feces cleaning and transporting vehicle or ight soil sludge pump by pipeline, described feces cleaning and transporting vehicle or ight soil sludge pump are connected with ight soil transport pipe, and described ight soil transport pipe is communicated with methane-generating pit.
Described floating matter disrupter is divider wall.
Described variable valve is for regulating cone valve.
The bottom in sewage ight soil filtering classification pond is downward-sloping doline.
The gradient of the bottom in described sewage ight soil filtering classification pond is 20%-40%.
The gradient of the bottom in described sewage ight soil filtering classification pond is 30%.
The utility model, by liquid dung is classified, first filters away floating matter, foreign material, then ight soil is delivered to methane-generating pit, adopts filter screen that sewage and ight soil are separated simultaneously, after sewage is effectively processed, delivers to resident or farmland storage pool.The ight soil biogas harmless treatment factory that delivers into pressure, ight soil goes out fertilizer with aerogenesis, and to biogas residue and biogas liquid deep processing, such as manufacturing compoiste fertilizer.
This system can effectively be processed existing municipal effluent, has both alleviated the pressure of existing urban sewage treatment system, can make full use of ight soil and sewage simultaneously, and the second stage employ to sewage, has saved water resources greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is called for short classification pond by sewage ight soil filtering classification pond 1(), the dirty water decontamination handles pond 2 and ight soil biogas harmless treatment factory three parts form.
The left and right sides in classification pond 1 is respectively equipped with liquid dung entrance 3 and spillway 4, in the interior position near liquid dung entrance 3, classification pond 1, be vertically provided with from top to bottom floating matter divider wall 5 and foreign material filter screen 6, floating matter divider wall 5 and foreign material filter screen 6 and sewage ight soil filtering classification pond 1 left side between the walls have formed isolation, floating matter and foreign material are blocked in the left side of floating matter divider wall 5 and foreign material filter screen 6, and right side is sewage and ight soil.For the ease of extracting ight soil, classification 1 bottom, pond is made into doline, and its gradient is 20%-40%, is generally 30%.Use ight soil sludge pump 7 or feces cleaning and transporting vehicle 8, ight soil is taken away, and sent into ight soil transfer line 9, ight soil transfer line 9 is sent into methane-generating pit 10, is further processed, and can directly export biogas or for generating etc.
Right side in classification pond 1 tilts to be provided with sieve for feces net 11, and it can stop ight soil to enter rightward space.Right side in classification pond 1 is also provided with an adjusting cone valve 12, regulates cone valve 12 to be connected with waste water transhipment pump 13, and waste water transhipment pump 13 connects the dirty water decontamination handles pond 2 by pipeline.Sewage is separated from ight soil, part sewage flows in the dirty water decontamination handles pond 2 from spillway 4, most sewage is by waste water, to transport pump 13 to enter in the dirty water decontamination handles pond 2, in the dirty water decontamination handles pond 2, be provided with compartment and filtering material, after processing, sewage up to standard is pressed into seconary water use pipeline by pipeline and seconary water use pump 14 and delivers to resident or farmland storage pool.
The ight soil biogas harmless treatment factory that delivers into pressure, ight soil goes out fertilizer with aerogenesis, and to biogas residue and biogas liquid deep processing, such as manufacturing compoiste fertilizer.
