Problems solved by technology

[0003] According to its chemical composition, flocculants can be generally divided into two types: inorganic flocculants and organic flocculants. The existing flocculants can play a role in sewage treatment, but their purification effect on water quality is not good enough, and their bactericidal ability is relatively weak. Some sewage with high bacterial content is difficult to meet the discharge standard after treatment

Abstract

The invention discloses a flocculating agent with a bactericidal function. The flocculating agent comprises the following raw materials by weight: 20-30 parts of aluminum sulfate, 8-12 parts of sodiumsilicate, 15-20 parts of polyferric sulfate, 6-8 parts of chitosan, 5-7 parts of sepiolite, 1-3 parts of zeolite, 5-8 parts of glacial acetic acid, 3-5 parts of chloropropylene oxide, 8-10 parts of an alcohol compound and 80-100 parts of water. The invention also discloses a preparation method for the flocculating agent with the bactericidal function. The flocculating agent prepared in the invention has strong water purification ability under the joint action of various raw materials and does not fuse with new pollutants in the process of water purifying; and the flocculating agent has strongbactericidal effect, can inhibit bacterial growth, is applicable to purification of sewage with high bacterium content and ensures purification effect.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a flocculant with sterilization function. Background technique [0002] Flocculant is currently the most widely used agent in sewage treatment. The flocculation process is an indispensable key link in the sewage treatment process. The flocculant is added to the sewage to make the suspended particles in the sewage lose stability, and the colloidal particles will coagulate each other. The particles increase to form flocs and alum. When the flocs grow to a certain volume, they will separate from the water phase and settle under the action of gravity, thereby removing a large amount of suspended solids in the wastewater, thereby achieving the effect of water treatment. Flocculant is currently the most widely used agent in sewage treatment, and the flocculation process is an indispensable key link in the sewage treatment process. [0003] Flocculants can be divided into inorganic f...
