Embodiment Construction

[0029] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] Such as figure 1 and figure 2 As shown, the small domestic sewage integrated processor system includes a grid well 1, a regulating reservoir 2, and a small domestic sewage integrated processor 3. A water inlet 11 is provided on the side wall of the grid well 1, and domestic sewage passes through the inlet. The water inlet 11 flows into the grid well 1, and the water inlet 11 of the grid well 1 is covered with a grid sheet 12, and the sundries and coarse suspended matter in the domestic sewage are filtered out through the grid holes of the grid sheet 12, and the grid The grid well 1 is provided with a first lift pump 13, the outlet of the first lift pump 13 is connected to the regulating reservoir 2, and the first lift pump 13 pumps the domestic sewage in the grid well 1 into the regulating reservoir 2 for Preliminary d...

Abstract

The invention discloses a domestic sewage treatment process. The domestic sewage treatment process comprises the following steps that 1, domestic sewage is discharged into a grating well through a discharge pipeline embedded underground; 2, the domestic sewage in the grating well is pumped into a regulating reservoir through a first lift pump, and the quality and quantity of the domestic sewage are balanced in the regulating reservoir; 3, the degraded domestic sewage in the regulating reservoir is pumped into the inner cavity of a machine body through a second lift pump, then a fan operates and performs exhausting towards an aeration head, the aeration head performs aeration for 4-6 hours, then the fan is stopped, and the domestic sewage in the inner cavity of the machine body is subjected to standing and sedimentation for 2 hours; 4, high-phosphorus sewage execution time and low-phosphorus sewage execution time are determined according to the actual domestic sewage discharge situation; 5, at the high-phosphorus sewage execution time, a first electric water discharging valve is turned on, a second electric water discharging valve is turned off, a discharge pump is started to input supernate of the domestic sewage into a phosphorous removal filtration device, and finally the treated domestic sewage is discharged into a sampling well and finally flows into a pollutant-holding water body.

Description

technical field [0001] The invention relates to a domestic sewage treatment process, which belongs to the technical field of sewage treatment. Background technique [0002] In recent years, various water treatment technologies have achieved continuous development in practical applications, especially the activated sludge process as a secondary treatment has become the mainstream process for urban sewage treatment due to its relatively mature process, stable operation, and good treatment effect. However, the traditional activated sludge not only has a large capital investment and high operating costs, but also mainly aims to remove carbon source pollutants, and removes little nutrients such as nitrogen and phosphorus. After the treated effluent is discharged into the water body, it will still cause pollution. For environmental problems such as eutrophication, although tertiary treatment can solve the above problems, it is difficult to promote in a large area due to high inves...
