Problems solved by technology

However, the activated sludge has a certain application time for the electric field, which prolongs the process time and increases energy consumption. At the same time, the reproductive ability of microorganisms is reduced, which reduces the reuse rate of activated sludge.

Abstract

The invention provides a domestic sewage treatment method, and belongs to the field of sewage treatment. The method comprises the steps of mesh filtration; precipitating adjustment, wherein a phosphorus removing agent is adopted; biochemical treatment, wherein sewage treatment is conducted through active sludge, an intermittent electrostatic field is set, and after the active sludge is pretreated by ultrasonic waves, tourmaline powder is added into the active sludge; precipitating adsorption, wherein porous adsorption filler is adopted as an adsorption material; wet land treatment. According to the method, the activity of microorganisms can be greatly activated, the adaptive capacity of the microorganisms to the electric field is improved, the sewage treatment time is shortened, reproduction of the microorganisms can be accelerated, the utilization rate of the active sludge is increased, and water body purification is promoted.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a domestic sewage treatment method. Background technique [0002] my country's water resources are scarce, and the per capita share is small. The content of substances in domestic water is complex. If it is discharged directly into the environment without treatment, it will pollute groundwater and seriously affect human health and the ecological environment. [0003] At present, sewage treatment is also vigorously promoted and developed at home and abroad. Domestic sewage has a relatively fixed composition, contains more organic matter, has strong biochemical properties, and is more suitable for the growth of bacteria. Therefore, most domestic sewage treatment methods are biochemical treatment. Electrostatic treatment technology is an important technology in water treatment. It uses electric field to act on microorganisms in water to cause biological effects and improve the activ...
