System for biochemically recovering and regenerated saving water in urban residence

Abstract

The present invention relates to a biochemical recovery and regeneration water saving system of town building and district. Seal the feces by plastic barrel and trailer for conveniently carrying. The air drafting and the water removing of the lower feeding pipe, the smell-proof air feeding pipe, the wind power fan and its canal fan prolong the period of storing feces to make them harmless to be fertilizer with good quality, improve the price and reduce the times of delivering fertilizer. It is the best to use the ground floor of the building, parkland for body-building or the basic of underground garage to resolve the problems of ladle car saving and channels. Otherwise, the scheme that one unit shares one basement and one channel has to be adopted as civil air defence facilities. The lavatory rushes the small pellet inside the pallet through soft hose and link rod all the way. It washes the plastic smell-proof device via round export and forms water seal by the pellet at the channel port through the urinal inner wall, which can save 95% water. The bathwater and the rainwater are purified by the sedimentation tank and the ultrafiltration membrane and flow into the pool for washing lavatory, cars and greening to save more water. The biochemical recovery and regeneration water saving system of town building and district provided by the present invention is a good technique to change the problem of high cost without economic benefit of urban wastewater treatment factory.

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 from the septic tank, the odor will be transmitted for a long time, and the residents will 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
