Example Embodiment
[0055] Example 1
[0056] A sewage treatment agent, including the following components in parts by weight:
[0057] 20 parts of polyacrylamide;
[0058] 10 parts of organic amine;
[0059] 10 parts of sodium hypochlorite;
[0060] 2 parts of compound scale inhibitor;
[0061] 1 part of inorganic corrosion inhibitor;
[0062] 1 part of acetic acid.
[0063] The composite scale inhibitor is a composite of organic phosphonic acid and polycarboxylic acid. When in use, put the above components into the sewage to ensure even distribution.

Abstract
The invention discloses a sewage treatment agent which comprises the following components in parts by weight: 20-60 parts of polyacrylamide, 10-30 parts of organic amine, 10-20 parts of sodium hypochlorite, 2-10 parts of a composite antisludging agent, 1-8 parts of an inorganic corrosion inhibitor and 1-10 parts of acetic acid. Compared with the prior art, the sewage treatment agent has the benefits that the formula comprises a flocculant, an adsorbent, a sterilizing agent, the antisludging agent, the corrosion inhibitor and a disincrustant, so that the water is comprehensively treated. The sewage treatment agent has the advantages that (1) the treatment scope is wide and the removal rate is remarkably increased; (2) the treatment effect is excellent, and the removal rate of suspended solids is up to be more than 90%; (3) the dewatering of the sludge is easy, a flocculating constituent is dense and is settled rapidly because of the used unique material, and the produced sludge is dewatered easily; (4) the cost of the materials is low, the sources of the materials are wide, the amount of the material used is low, and the advantage of low cost is achieved; (5) the sewage treatment agent is non-toxic, harmless, and easy to store.
Description
technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a sewage treatment agent. Background technique [0002] Sewage treatment is the process of making sewage meet the water quality requirements of a certain water body for drainage or reuse, and purifying it. 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, in...
