Problems solved by technology

Coagulants can be divided into inorganic low-molecular coagulants, inorganic polymer coagulants and organic polymer coagulants. These types of coagulants have certain defects during use, such as aluminum-based and iron-based coagulants. The dosage of coagulant is large, the amount of sludge produced is large, there are health and safety hazards, the cost of polyacrylamide is high, and the production raw materials have "three effects" effects, etc.

Abstract

The invention provides a non-toxic flocculating agent for sewage treatment. The non-toxic flocculating agent for sewage treatment, which is provided by the invention, is characterized by comprising the following components in parts by weight: 20 to 30 parts of whole wheat flour, 5 to 12 parts of sodium silicate, 6 to 15 parts of chitosan, 30 to 50 parts of porous pearlite micropowder of 200 to 300meshes and 35 to 50 parts of zeolite powder of 200 to 300 meshes. The non-toxic flocculating agent for sewage treatment is low in cost and non-toxic, avoids secondary pollution, has good flocculatingeffect, and is stable in structure and low in cost.

Description

Technical field: [0001] The invention relates to a non-toxic flocculant for sewage treatment, which belongs to the technical field of sewage treatment chemicals. Background technique: [0002] Coagulation sedimentation is currently the most commonly used physical and chemical treatment method in the water treatment process. It is a key link in the treatment process, and its treatment effect is closely related to the type and performance of the coagulant. Coagulants can be divided into inorganic low-molecular coagulants, inorganic polymer coagulants and organic polymer coagulants. These types of coagulants have certain defects during use, such as aluminum-based and iron-based coagulants. The dosage of coagulant is large, the amount of mud produced is large, there are health and safety hazards, the cost of polyacrylamide is high, and the production raw materials have "three-to-one" effects, etc. With the continuous improvement of water quality standards, it is very important ...
