Biochemical recover and regeneration water-saving system for urban building and community

Abstract

The invention relates to a biochemical recovery and regeneration water-saving system for urban buildings and communities. Feces is sealed in transportation by a plastic barrel and a trailer, and the transportation is convenient; a lower feces delivery pipe, a stink prevention gas pipe, a wind-energy fan and an in-pipe fan driven by the wind-energy fan carry out air draft and water removal to prolong the feces storage time, so that human waste is harmless to become high-quality fertilizer, the price is increased, and the frequency of fertilizer delivery is reduced. The storage and passage for the plastic barrel and the trailer is preferably solved by utilizing a building ground floor which is used as a garage or a public fitness filed and an underground garage foundation or adopting the scheme that a unit shares a basement and a passage which are also used as a civil air defense facility. Toilet-flushing water of a novel flush toilet passes through a flexible rubber pipe and a connecting rod to flush a small ball in a ball, flows out of a round outlet to flush a plastic stink preventer and then flows through the inner wall of the toilet to form water seal at a channel port, water can be saved by 95 percent, and bath water and rain water enter a sedimentation tank, is purified by an ultrfiltration membrane and then flows into a water pool to be used for flushing toilet, washing cars and greening, thereby more water is saved. Supersonic air drier can be used to carrying out fast air drying treatment for human waste to realize industrialized production.

Description

technical field [0001] The invention relates to a biochemical recovery and regeneration water-saving system for urban buildings and communities. It belongs to the category of resource reuse and environmental protection. Background technique [0002] At present, the human waste (piss and urine) of urban residents is either picked up in a septic tank and then sent away, or poured into a car with a toilet and transported away, or treated by an urban sewage treatment plant and then discharged, but most of them are directly discharged through the sewer. In the rivers, rivers, lakes, and seas, excrement accounts for 80% to 90% of the total amount of pollution. During the "Ninth Five-Year Plan" period, the state needs to invest 450 billion yuan to control pollution. Compared with the 37.579 billion yuan during the "Eighth Five-Year Plan", 600 more urban sewage treatment plants will be built on the basis of more than 300 urban sewage treatment plants, but this can only solve 40% to...

Problems solved by technology

Some key problems are difficult to solve, such as: 1. Raw manure has not been stored for a certain period (usually one month), and germs are easy to spread randomly when using it, which will damage the health of users

Raw manure fertilization pollutes crops

2. When it is fished or extracted through the septic tank, the odor will be spread for a long time, and the residents do not accept it.

Due to uncontrolled flushing water, the manure is over-diluted and the fertility is insufficient. Farmers do not welcome it

At the same time, the human waste water in salvage and transportation accounts for a large proportion, and the transportation cost and ineffective labor are increased, so that the selling price of human waste is reduced.

3. Cities with a lot of toilets, such as Shanghai, give away waste once a day (toilets have limited volume and are inconvenient to store for a long time), which is not only easy to infect germs, but also conflicts with the seasonal seasons of fertilization in rural areas, which can easily cause excessive manure. situation
