Integrated sewage treatment equipment and sewage treatment method

Abstract

The invention discloses integrated sewage treatment equipment and a sewage treatment method, wherein the integrated sewage treatment equipment comprises a water-medicine mixing tank, a first-stage dosing machine, a dissolved air flotation machine, a defoaming machine, a first-stage precipitation tank, a drainage dosing CBAM mixing pipe, a filter bed, a second-stage dosing machine, a biochemical tank, a second-stage precipitation tank, a purification tank, a disinfection tank and a discharge pipe. The dissolved air flotation machine is provided with a water medicine dissolving box, an air flotation box, a settling box, a clear water flow guide pipe, an air-water separation pump, an air dissolving machine, a releaser, a slag scraper, a slag outlet, a clear water discharge pipe and a supernatant box. According to the invention, multi-unit sewage treatment equipment in the prior art is modified into the all-in-one structure, and the discharge index of sewage treated by the sewage treatment equipment meets the national A-level sewage discharge standard requirement.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated sewage treatment equipment and a method for using the same. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, Various fields such as catering are also increasingly entering the daily life of ordinary people. [0003] However, in the prior art, there are at least the following technical defects in the current treatment technology about sewage: [0004] 1. There are many and scattered processing equipment, lack of integrated equipment, and difficult management; [0005] 2. Cannot meet the national A sewage discharge standard requirements; [0006] 3. The efficiency of se...

AI Technical Summary

Problems solved by technology

[0004] 1. There are many and scattered processing equipment, lack of integrated equipment, and difficult management;

[0005] 2. Cannot meet the national A sewage discharge standard requirements;

[0006] 3. The efficiency of sewage treatment is low. The existing integrated equipment can only be used for small and medium-sized water plants, not for large water plants, for example, not suitable for water plants with more than 1,000 tons;

[0007] 4. The processing process is cumbersome, a lot of manpower and material resources are wasted, and it is difficult to carry out automatic, streamlined and industrialized operations;

[0008] 5. The sewage treatment process cannot be completed at one time, and the workplace needs to be changed frequently;

[0009] 6. Recycled materials cannot be reused, and cannot create economic value, etc.
