Waste pollution ecological comprehensive treatment system

Abstract

The invention discloses an ecological comprehensive treatment system of waste. The ecological comprehensive treatment system comprises a waste treatment device, a power device, a reaction device, a slag-slurry treatment device and a biogas-pressure balancing and biogas conveying device. The facility built by applying the technology of the invention is in totally-enclosed type operation, has no secondary pollution to the environment and has no fault of pipeline blocking operation; solid waste and liquid waste can be treated simultaneously; for the farming waste, pretreatment of dry-wet separation of feces is not needed, conveying and reaction conversion of materials are realized by utilizing self circulation of the whole slurry, an independent mechanical stirring device is not needed, so that the garbage such as farming waste is fully utilized so as to obtain energy and fertilizers; compared with the existing treatment mode, the ecological comprehensive treatment system has the characteristics that the concentration is strong, more thorough utilization of waste utilization is realized, the treatment cost is reduced and the benefit is generated, so that the slag-slurry treating device is commonly applicable to harmless treatment of urban domestic garbage, domestic sewage, excrement from rural farming, waste from agricultural planting and waste from forest growth.

Description

technical field [0001] The invention relates to a waste sewage treatment system, in particular to a waste sewage comprehensive treatment system Background technique [0002] The effective treatment of urban domestic garbage, domestic sewage, rural breeding excrement, and agricultural planting waste has become a major scientific and technological project of concern to countries all over the world. The current treatment methods of urban waste landfill and waste power generation have caused serious environmental secondary pollution, and the fecal waste produced by animal breeding has no better disposal method for animal breeding excretion. In the prior art, there have been Some reaction equipment used for slurry treatment after solid-liquid separation of aquaculture excrement, but due to the complex composition of aquaculture waste, problems such as system pipeline blockage often occur, and the structure is complex and the failure rate is high, resulting in the existing aquacul...

Problems solved by technology

The current treatment methods of urban waste landfill and waste power generation have caused serious environmental secondary pollution, and the fecal waste produced by animal breeding has no better disposal method for animal breeding excretion. In the prior art, there have been Some reaction equipment used for slurry treatment after solid-liquid separation of aquaculture excrement, but due to the complex composition of aquaculture waste, problems such as system pipeline blockage often occur, and the structure is complex and the failure rate is high, resulting in the existing aquaculture waste Most of the sewage treatment devices are out of service, and the aquaculture waste will cause serious pollution to the environment

Due to the above reasons, most of the breeding waste is directly separated from wet and dry, and then solid stacking and fermenting, and the remaining urine slurry is directly discharged into the open-air biogas digester. The open-air biogas digester also receives biogas slurry Receiving a large amount of rainwater, discharge and transportation are extremely inconvenient; the volatilization of gas in the retting solids exposed to the cow dung shed, the evaporation of the open-air digester, and the more serious rainstorms will expose the immersion and leakage of the retting solids in the cow dung shed, which will have a negative impact on the surrounding environment. Cause extremely bad influence, and the scope of influence is large
