Sewage treatment agent according to the type of different, can be divided into organic and inorganic, inorganic commonly used poly aluminum chloride, ferrous sulfate, poly aluminum chloride, etc., and organic can be divided into cationic polyacrylamide, Anionic polyacrylamide, nonionic polyacrylamide, etc., can be used as a sewage treatment agent in different water treatment applications.
First, the main purpose:
1, sewage treatment
In the use of inorganic coagulants, flocculants in the sewage treatment system, such as the need to deal with the large amount of water over the clarification pool of the processing capacity or due to other factors caused by water floc too near the settlement and drift, just add 0.1-2ppm Polyacrylamide PAM coagulation, you can significantly improve the settlement effect. Moreover, the COD and chromaticity indicators of the treated water will also be significantly improved.
2, sludge concentration
The use of 0.3-2ppm can reduce the proportion of sludge and water in the biochemical and sludge concentrates, and improve the utilization rate of the biochemical and sludge enrichment tanks. The sludge concentration can be increased from 3 --- 10g / L to 30-100g / L, which greatly reduces the sludge weight of the next sludge dewatering process and improves the efficiency of sludge dewatering equipment and personnel.
3, sludge dewatering
Type and dosage and dehydration after the dry cake and as the kind of sludge and different, so the need for different types of products to test the choice. Cationic polyacrylamide CPAM Features:
1, polyacrylamide molecules with a positive gene, flocculation ability, with less, the treatment effect is obvious.
2, good solubility, high activity, in the water in the formation of alum large, settling faster than other water-soluble polymer polymer purification capacity of 2-3 times.
3, the adaptability of water PH value and temperature of small impact, raw water purification to the national reference water standards, after treatment of suspended particles in water to achieve the purpose of flocculation clarification, is conducive to ion exchange treatment and preparation of high purity water. The same time as
4, corrosive, easy to operate, can improve the labor intensity of labor and labor conditions.
Second, packaging, reserves
1, double-layer kraft paper bag with moisture-proof film, specifications 25kg / bag. Products are moisture-absorbing, should not be exposed, should avoid sun and rain.
2, product retention period of two years.
