Problems solved by technology

[0004] In the process of sewage oxidation treatment, it is necessary to put a certain amount of oxidant into the sewage to oxidize the sewage, but the existing oxidant has poor oxidation effect, large dosage, and poor reaction effect, which makes the time of sewage oxidation treatment longer and the oxidation The total amount of sewage after treatment increases, thus increasing the workload of sewage treatment, which is not conducive to the actual treatment of sewage

Embodiment Construction

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but 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 creative efforts fall within the protection scope of the present invention.

[0017] The present invention is a high-grade oxidant for sewage treatment, its raw materials are by weight percentage: 5%-15% of ferrous sulfate, 5%-15% of potassium perchlorate, 2%-5% of potassium permanganate, 10%-10% of sodium bicarbonate 20%, compound acid 25%-40%, polyacrylamide 20%-30%, ferrous sulfate, potassium perchlorate and potassium permanganate work together to effectively oxidize the sewage, so that harmful substances in the sewage can be oxidized and precipitated At the same time, the use of potassium permanganate can effe...

Abstract

The invention discloses a preparation method of an advanced oxidant for sewage treatment, and relates to the technical field of sewage treatment. The method comprises the following steps: SS01 weighing quantitative ferrous sulfate, potassium perchlorate, potassium permanganate, sodium bicarbonate, glacial acetic acid, citric acid and polyacrylamide according to weight percentage, and then respectively putting the weighed ferrous sulfate, potassium perchlorate, potassium permanganate, sodium bicarbonate, glacial acetic acid, citric acid and polyacrylamide into a grinder for grinding treatment.According to the invention, the sewage is subjected to oxidation treatment through the combined action of the ferrous sulfate, potassium perchlorate and potassium permanganate, so that harmful substances in the sewage are oxidized and separated out; meanwhile, the potassium permanganate can effectively prevent the ferrous sulfate and potassium perchlorate from being oxidized by air, so that the advanced oxidant is easier to store; the use of composite acid accelerates the efficiency of sewage oxidation treatment; the sodium bicarbonate reacts with the sewage to generate carbon dioxide, so thatthe sewage is stirred, and the efficiency of sewage oxidation treatment is further accelerated.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a method for preparing an advanced oxidant for sewage treatment. Background technique [0002] With the continuous advancement of science and technology and the continuous development of the chemical industry, people's lives have become more convenient and diversified, but while enjoying the convenience, the pollution caused by chemical production has become more and more serious, which has to arouse people's attention and attention . In the process of chemical production, in addition to air pollution, water pollution is even more serious, especially now that water resources are very precious, chemical pollution directly threatens water sources, affecting people's health and normal life. [0003] Now the water that people in the city drink is treated tap water. With the continuous pollution of water sources, sewage treatment is imperative. Sewage treatment is widely use...
