Embodiment Construction

[0025] Such as figure 1As shown, a domestic sewage treatment and reuse method, the domestic sewage is classified and collected, and divided into high-concentration black water and low-concentration gray water according to the nature and source of sewage. After the black water is discharged, it passes through the Anaerobic treatment pool 1, aeration contact oxidation pool 2, aeration high pollution resistance ecological pool 3, aeration low pollution resistance ecological pool 4 and ecological sedimentation treatment pool 5, the treated black water and gray water are combined and then enter the adjustment pool 6. After being regulated by the regulating tank 6, it is sent to the underground infiltration device 7 for treatment, and the water treated by the underground infiltration device 7 is disinfected and reused for flushing the toilet or discharging up to the standard.

[0026] In the embodiment of the present invention, the treatment time of the anaerobic treatment pond 1 is...

Abstract

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.

Description

technical field [0001] The invention relates to the field of environmental engineering, in particular to a method for treating and recycling domestic sewage in residential quarters. Background technique [0002] At present, most of the domestic sewage in my country adopts the traditional treatment method, that is, the sewage is collected through the sewage collection pipe network and then transported to the sewage treatment plant for treatment. This treatment method has the following defects: 1. The construction cost of sewage treatment process facilities and sewage pipe network 2. Sewage often consumes power during transportation, which increases operating costs; 3. Sewage is prone to leakage during transportation in the pipe network, causing pollution; 4. The centralized treatment method makes it necessary to rebuild the pipe network or transport it for water reuse. , increasing the cost of reuse. Therefore, with the prominence of the shortage of water resources, and based ...
