The invention relates to the field of
environmental engineering, in particular to a method for treatment and recycling of residential district domestic
sewage. According to a scheme adopted by the invention, the domestic
sewage treatment and reuse method is characterized in that: the domestic
sewage is classified and then discharged, according to different natures and sources of the sewage, the sewage is divided into
high concentration black water and low concentration grey water, the black water is drained and separated, and then passes through an
anaerobic treatment tank, an
aeration contact oxidation tank, an
aeration high
stain resistant ecological tank, an
aeration low
stain resistant ecological tank and an ecological
sedimentation treatment tank in order, the treated black water is combined with the grey water, then the mixture enters a regulation tank for regulation and is then sent into an underground infiltration device for treatment, the water treated by the underground infiltration device is disinfected and then used for
toilet flushing or up-to-standard
discharge. By means of the scheme, the invention, directed at the problems in existing
sewage treatment systems, puts forward the technological method for effective on-site treatment and reuse of domestic sewage.
