Embodiment Construction

[0012] As shown in the figure: the zero-discharge facility for domestic sewage treatment in urban residential quarters includes an anaerobic-aerobic integrated device 1 , seepage channels 2 , green land 5 , and a storage pool 6 . The collected domestic sewage is pumped into the bottom of the anaerobic pool 8 of the anaerobic-aerobic integrated device 1 with the water pump 11, and the anaerobic pool generates biogas. The biogas is exported from the biogas output pipe 14 . The overflow pipe 12 of the anaerobic tank 8 , the water tank 13 , and each of the multiple double-chamber filter tanks 9 and the storage tank 6 communicate with each other. Wherein, the bottoms of chamber A and chamber B of the double-chamber filter are connected. Water overflows from the overflow pipe 12 of the anaerobic tank 8 to the water tank 13, overflows from the edge of the water tank 13 to the A cavity of the uppermost double-chamber filter tank 9-1, flows back from the A cavity to the B cavity, and ...

Abstract

A zero discharge facility for domestic sewage treatment in urban residential areas includes an anaerobic aerobic integrated device (1), a water infiltration channel (2), a green belt (5) and a storage tank (6), and is characterized in that collected domestic sewage is pumped into the anaerobic aerobic integrated device (1) by a water pump (11), overflowed water respectively flows into a water infiltration layer (3) by the water infiltration channel (2), overflows into the green belt (5), and then overflows into the storage tank (6); overflows into a wetland (the green belt is changed into the wetland, and aquatic landscape plants are cultured in the wetland ), and then overflows into the storage tank (6); and water in the storage tank (6) is sent back to users by a sewage pump (7) for washing toilets or spraying road surface to realize zero discharge.

Description

technical field [0001] The invention relates to a sewage treatment facility, in particular to a zero-discharge facility for domestic sewage treatment in urban residential quarters. Background technique [0002] Common problems in current domestic sewage treatment: first, pollutants cannot be completely removed, leading to economic development giving way to pollution control; second, there are only environmental benefits and no economic benefits, causing sewage enterprises to passively treat sewage; The resources are removed as pollutants, such as nitrogen, phosphorus and other nutrients, nutrients and other organic matter, and it is a waste of resources to spend money on. Therefore, designing a facility that can fully utilize the resources in the domestic sewage is a technical problem that needs to be solved urgently at present. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a facility that can make full use of...
