Community septic tank sludge and kitchen garbage co-treating system

Abstract

The invention relates to a community septic tank sludge and kitchen garbage co-treating system which comprises a residential building drainage system, a vacuum pollution discharge system and a fermentation fertilizer making system, the residential building drainage system at least comprises a kitchen drainage vertical pipe and a urinal drainage vertical pipe, and the kitchen drainage vertical pipeis used for discharging kitchen wastewater and kitchen garbage; the urinal drainage vertical pipe is at least used for discharging excrement, and the vacuum pollution discharge system comprises a septic tank, a vacuum tank and a vacuum tank sludge discharge pump; the septic tank is communicated with the kitchen drainage vertical pipe and the urinal drainage vertical pipe so as to contain kitchenwaste water, kitchen garbage and excrement and precipitate the kitchen garbage and the excrement to form sludge, a conveying pipe is arranged between the septic tank and the vacuum tank, an automaticvalve is arranged on the conveying pipe, and the automatic valve is communicated with the vacuum tank, the automatic valve can be opened at regular time so as to discharge sludge in the septic tank into the vacuum tank, and the sludge discharge pump of the vacuum tank sucks the sludge from the vacuum tank and conveys the sludge to the fermentation fertilizer preparation system for fertilizer preparation.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a system for co-processing community septic tank sludge and kitchen waste. Background technique [0002] Sludge from community septic tanks is formed after residents’ excrement drains into the septic tanks and settles at the bottom of the septic tanks. After a long period of anaerobic digestion, the septic tanks need to be cleaned by a suction truck every six months. , The cleaned up septic tank sludge is transported to the septic tank sludge treatment plant for landfill or incineration after anaerobic digestion and dehydration treatment. Kitchen waste is food processing waste and leftovers in the daily life of residents. The current treatment methods are mixed with domestic waste, or collected separately and transported to the kitchen waste treatment terminal. The current treatment methods for septic tank sludge and kitchen waste have the following deficiencies...

AI Technical Summary

Problems solved by technology

[0003] 1. In the process of suction and cleaning of septic tanks, a large amount of unpleasant odor will be emitted, which will affect the living environment of the community, and the cleaning and transportation costs will be high; the sludge taken out will be incinerated or landfilled to waste organic resources

[0004] 2. During the collection process of kitchen waste, it is easy to produce leachate drips, leaks, corruption and odor, and the transportation cost is high
