Abstract

The invention discloses a sewage treating agent and a preparation method thereof. The sewage treating agent is prepared from the following materials in parts by mass: 20 to 40 parts of polyferric chloride, 20 to 50 parts of isopropanol, 20 to 40 parts of sodium polyacrylate, 20 to 50 parts of disodium ethylenediamine tetraacetate, 10 to 30 parts of citric acid, 40 to 60 parts of bentonite, 20 to 40 parts of diallyl dimethyl, 20 to 40 parts of potassium dihydrogen phosphates, 20 to 40 parts of sodium gluconate, 20 to 40 parts of tert-butyl hydroperoxide, 20 to 40 parts of sodium dodecyl benzene sulfonate, 20 to 40 parts of dichloroether, 20 to 40 parts of tetramethylethylenediamine and 50 to 100 parts of deionized water. According to the sewage treating agent which is provided by the invention, the preparation method is simple and is easily operated; the prepared sewage treating agent is quick in reaction speed; no poisonous and harmful gases are generated in a process; no corrosion is generated to equipment and a pipeline; no pollution is generated to an environment; the sewage treating agent is good in stability and high in safety.

Description

technical field [0001] The invention relates to a sewage treatment agent, which belongs to the technical field of sewage treatment. Background technique [0002] The lack of water has become a concern of the world. The country has strict requirements on the discharge of domestic sewage. The country has adopted corresponding compulsory measures to seek an effective sewage treatment agent that can meet the sewage discharge requirements after sewage treatment. This is an urgent need for many enterprises to solve. problem. Sewage treatment technology plays a very important role in water saving, energy saving and other issues, and there is an urgent need for a treatment agent with good treatment effect and no pollution. At the same time, the preparation methods of the existing sewage treatment agents are complicated, difficult to operate, and the labor cost for making them is relatively high. Contents of the invention [0003] The purpose of the present invention is to provid...
