Embodiment 1

[0022] A sewage treatment process, comprising the steps of:

[0023] (1) Filtration: Collect the sewage in the sewage treatment tank and stir for 20 minutes while stirring

[0024] While adding components by weight: 30 parts of polyaluminum iron silicate, 16 parts of slime fungicide, 20 parts of hydrogen peroxide, 6 parts of non-phosphorus environment-friendly scale inhibitor, 8 parts of inorganic corrosion inhibitor, and 20 parts of acetic acid Treatment agent, and then carry out precipitation, after precipitation, filter the sewage, the filter screen used for filtration is 400 mesh;

[0025] (2) Collection: collect the sewage obtained after filtering in step (1), and put it into the sewage pool

[0026] In the sewage tank, the components added in parts by weight are: 94 parts of potassium aluminum sulfate dodecahydrate, 4 parts of hydroxypropyl methylcellulose, and 2 parts of polyacrylic acid slow-release dephosphorization agent. Phosphorus agent, react, and the reaction t...

Embodiment 2

[0029] The rest are the same as in Example 1, except that in the step (1), the sewage is collected in the sewage treatment tank and stirred for 30 minutes, and the components in parts by weight are added while stirring: polymerized iron aluminum silicate 30 16 parts, slime fungicide 16, hydrogen peroxide 20, phosphorus-free environment-friendly scale inhibitor 6, inorganic corrosion inhibitor 8, acetic acid 20, and then carry out precipitation. After the precipitation, the sewage is filtered. The net is 600 mesh.

Embodiment 3

[0031] The rest are the same as in Example 1, except that in the step (1), the sewage is collected in the sewage treatment tank and stirred for 30 minutes, and the components in parts by weight are added while stirring: polymerized iron aluminum silicate 30 16 parts, slime fungicide 16, hydrogen peroxide 20, phosphorus-free environment-friendly scale inhibitor 6, inorganic corrosion inhibitor 8, acetic acid 20, and then carry out precipitation. After the precipitation, the sewage is filtered. The net is 800 mesh; in the step (2), the sewage obtained after filtering in the step (1) is collected, put into the sewage tank, and then the components by weight are added in the sewage tank: dodecahydrate 94 parts of aluminum potassium sulfate, 4 parts of hydroxypropyl methylcellulose, and 2 parts of polyacrylic acid slow-release dephosphorization agent are used for the reaction, and the reaction time is 30 minutes.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a sewage treatment process. Background technique [0002] Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., while domestic sewage is sewage produced in daily life, which refers to a complex mixture of various forms of inorganic and organic substances, including: floating and suspended solid particles of large and small sizes; colloidal and Gel-like diffuser; pure solution. [0004] According ...
