Embodiment Construction

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] A sewage treatment method, comprising the steps of:

[0027] 1) Sewage pretreatment: First, the sewage is input into the coarse grid filter device to remove large particles of impurities in the sewage, and then the filtered sewage is transported from the coarse grid filter device to the fine grid device through the water pump, and the fine grid filter is used The device filters small particles of impurities in the sewage, and the filtered sewage enters the oil-water sep...

Abstract

The invention relates to the technical field of sewage treatment, and discloses a sewage treatment method which comprises the following steps: 1) sewage pretreatment, 2) softening treatment, 3) flocculation treatment, 4) heavy metal removal treatment, 5) heavy metal content detection, 6) biochemical treatment, 7) organic matter content detection, 8) secondary precipitation treatment and 9) disinfection treatment. According to the sewage treatment method, insoluble substances in sewage are sequentially removed through step 1) sewage pretreatment, step 2) softening treatment and step 3) flocculation treatment, then heavy metal ions in the sewage are removed through step 4) heavy metal removal treatment, and BOD and COD contents in the sewage are reduced through step 3) flocculation treatment. Organic matters in the sewage are degraded through biochemical treatment in the step (6), so that the problems that the existing industrial sewage mainly adopts a biological treatment method matchedwith a physical treatment method and a chemical treatment method, but the treatment method is still complex and the cost is relatively high are solved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment method. Background technique [0002] Sewage treatment: the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. In various fields, more and more people have entered the daily life of ordinary people. The biochemical treatment method is referred to as the biological treatment method or biochemical method. The treatment process of this method is to make wastewater or solid waste mixed with microorganisms, and use the biological Chemical action decomposes organic matter and certain inorganic poisons (such as cyanide, sulfide, etc.) in wastewater, and converts unstable organic matter and inorganic poisons into ...
