Sewage treatment agent polyaluminium chloride

All the purified water plants that use surface water as the source of urban drinking or industrial water, as well as various industrial wastewater, urban sewage purification treatment, oilfield groundwater reinjection and sludge disposal, often use flocculation as an indispensable part of many treatment processes. Pre-key process technology. The effect of flocculation treatment determines the operation status of the subsequent treatment process to a large extent, and ultimately the quality and cost of the effluent. Water purifying agent Polyaluminium chloride is currently the most widely used and most widely used water treatment chemical. Polyaluminium chloride has the advantage of wide water area, so what kind of sewage treatment is better?

First, the treatment of domestic water after being used, that is, the treatment of washing wastewater. Because there are a lot of surfactants in water, if the agent reacts with the interaction of oil and dust particles, it will form colloidal particles with negative charges, which is easy to remain in water stably. If a proper amount of polyaluminium chloride is added to wastewater, a large number of cations with positive charges and multi-nucleus high charge complex ions formed by base bridging will be produced, which can make the charges suspended on the surface of colloidal particles have a strong ability to absorb and neutralize electricity and compress the double layer, thus destabilizing colloidal particles, and then adsorbing and precipitating pollutants to separate water bodies.

Second. Paper-making wastewater treatment has a large amount of wastewater discharged from paper industry, a large proportion of which comes from section water treatment. Moreover, black liquor from many papermaking enterprises is mixed with middle water after pretreatment (anaerobic, strong acid treatment, cellulose separation, neutralization, etc.). It makes the harmful substances in paper-making wastewater increase. With the increase of salinity, the removal rates of COD and SS increased in the treatment of paper-making mid-stage water by coagulation and precipitation with polyaluminium chloride. It should be noted here that after 75% salinity, the removal rate decreases. The effluent can meet the national discharge standard by adding 0.6gL of polyaluminium chloride with 75% salinity at 250 C. Polyaluminium chloride (PAC) has a very powerful function. In addition to the reduction of residual turbidity chroma, the coagulation effect is characterized by floc formation, high adsorption performance and good filtration and dewatering performance of sludge. Especially in the treatment of high turbidity water, low temperature and low turbidity water, the treatment effect is better than that of alum, polyferric sulfate and ferric oxide. It is soluble in water and can be used for drinking water, industrial water, industrial wastewater and domestic sewage treatment. Among them, the purification effect of low temperature and low turbidity water is particularly obvious, which can not be compared without alkaline additives and other coagulants.
