According to the flocculation test, the inorganic flocculant has a good flocculation effect, but the addition amount is large and the treatment cost is high: the organic flocculant has a slightly poor flocculation effect, but the treatment cost is low. The flocculation mechanism of inorganic flocculant is double electric layer compression and electric neutralization, while the flocculation mechanism of organic flocculant is net capture and bridging. For cationic polyacrylamide, it also has the function of charge neutralization.
The polyaluminum chloride with good flocculation effect and low cost in the inorganic flocculant and the ultra-high dosage cationic polyacrylamide with good flocculation effect and low cost in the organic flocculant are selected for the composite test to make the advantages of the inorganic flocculant and the organic flocculant complement each other and give play to their synergy, so as to further improve the flocculation effect and reduce the cost of sewage treatment.
