Domestic sewage zero discharge system

Abstract

The invention discloses a domestic sewage zero discharge system. The domestic sewage zero discharge system comprises a sewage regulating system, an integrated domestic sewage treatment system and a recycling pressurization system, wherein a fermenting tank water outlet shaft and a sewage integrated grid hoisting shaft are included in the sewage regulating system; a precipitation / hydrolysis / acidification tank, a biological contact oxidation tank, a precipitation tank, a sludge digestion tank, a multimedia activated charcoal haydite filtering tank, a disinfection / recycling tank and a blower are included in the integrated domestic sewage treatment system; an evaporator is included in the recycling pressurization system; the precipitation / hydrolysis / acidification tank, the biological contact oxidation tank, the precipitation tank and the multimedia activated charcoal haydite filtering tank are sequentially communicated; the precipitation / hydrolysis / acidification tank, the biological contact oxidation tank, the precipitation tank and the multimedia activated charcoal haydite filtering tank are respectively communicated with the sludge digestion tank; and sewage enters the disinfection / recycling tank through the multimedia activated charcoal haydite filtering tank. According to the invention, domestic sewage can be recycled after being treated, thus realizing zero water discharge in a living zone and bringing huge social benefits and economic benefits.

Description

Technical field [0001] The invention relates to a water treatment system, in particular to a zero discharge system for domestic sewage. Background technique [0002] With the development of society and the continuous advancement of science and technology, people’s living standards continue to improve, resulting in more and more domestic garbage and sewage. If the domestic sewage cannot be treated in time, it will not only bring great pollution to the living environment , And wastes too much resources. The existing domestic sewage treatment system has low purification efficiency. The purified sewage is still polluted and caused great waste. Most of the purification systems are affected by seasonality and are not stable enough. , Resulting in unsatisfactory purification treatment effect. Therefore, in response to the above problems, we propose a zero discharge system for domestic sewage. Summary of the invention [0003] The invention provides a domestic sewage zero discharge syste...
