Abstract

The invention relates to the field of water treatment agents, and particularly discloses a sterilization algicide for coking sewage treatment and a preparation method thereof. The sterilization algicide for coking sewage treatment comprises a porous load matrix and a coating layer arranged on the porous load matrix in a filling mode, wherein the coating layer comprises, in parts by weight, 10-15 parts of chitosan, and 6-8 parts of a composite beneficial bacterium agent; and the compound beneficial bacterium agent comprises one or more of a bacillus pumilus agent, an actinomycete agent, a lactobacillus fermentum agent and a lactobacillus casei agent. The preparation method comprises the preparation steps of S1, performing preliminary compounding; S2, performing secondary mixing; and S3, grinding and compounding. According to the invention, a composite system formed by the porous loading matrix and the coating layer of the beneficial bacterium agent is adopted, so that the service life of the sterilization algicide is prolonged, and good sterilization and algicide effects are achieved.

Description

technical field [0001] The application relates to the field of water treatment agents, more specifically, it relates to a bactericide and algicide for coking sewage treatment and a preparation method thereof. Background technique [0002] Coking sewage is produced in the process of high-temperature dry distillation of coal, gas purification and refining of chemical products, and its main sources are: (1) residual ammonia water. (2) Process drainage of chemical products. (3) The final cooling water of crude benzene and the sewage of gas desulfurization and gas final cooling cycle. (4) Wastewater from the tar workshop: According to the different boiling points of organic matter, the tar workshop initially separates various products by distillation, and then separates crude benzene, pyridine and other products through acid-base washing. (5) Coomalon wastewater. [0003] Since the coking sewage is in the actual treatment process, its own environment is particularly suitable f...
