Polyacrylamide (PAM) is a high molecular polymer that is often used to treat wastewater from ceramic factories. It has strong adsorption, precipitation and flocculation effects, and can effectively remove suspended matter, particulate matter, grease and other pollutants in wastewater.

The process of treating wastewater from ceramic factories usually includes the following steps:

Purification pretreatment: The wastewater is filtered through primary filtration to remove large particles and suspended solids, such as pretreatment through equipment such as screens and grit chambers.

Polyacrylamide addition: Add an appropriate amount of polyacrylamide to the wastewater. PAM exists in the form of particles or powders, which can be directly dissolved in water to form a solution, or prepared into an emulsion and then added. The adsorption effect of PAM can cause fine particles to aggregate into larger clumps, which is convenient for subsequent treatment.

Coagulation and flocculation: Polyacrylamide and pollutants in wastewater have charge attraction to form floccules. These floccules can quickly settle or float to the surface of the water, thereby achieving the purpose of separation and removal. Flocculants can be used to precipitate or float the floccules together with other impurities in the solution.

Clarification and filtration: The wastewater after coagulation and flocculation is sent to the filtration device for further clarification and filtration through the filter screen or filter membrane. This step can remove fine particles and residual flocculants, making the wastewater clearer and more transparent.

Post-treatment disinfection: The wastewater after the above treatment may contain microorganisms or organic residues. In order to ensure that the wastewater meets the discharge standards, certain disinfection measures can be taken, such as ultraviolet irradiation, chlorination, etc., to kill bacteria and pathogens.

It should be noted that the use of polyacrylamide should be adjusted and optimized according to the specific situation, including dosage, dissolution method, coagulation time, etc. At the same time, relevant laws and regulations and environmental protection requirements should be strictly observed during the treatment process to ensure that the wastewater treatment meets the safety and environmental protection standards.
