Beijing Shuibiqing Environmental Protection Technology Co., Ltd. Silicone defoamer Zhuozhou quality merchantsPacking specification: Polyferric sulfate must be dissolved before it can be used. The dissolving equipment and processing facilities should be made of corrosion-resistant materials.
Industrial wastewater treatment: for suspended particles, coarser, high-concentration, positively charged particles, and the pH of the water is neutral or alkaline, iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, etc. Sewage treatment, effect. Drinking water treatment: Many water plants in our country source water from rivers. The content of sediment and minerals is high and relatively turbid. Although it is filtered through sedimentation, it still cannot meet the requirements, and flocculants need to be added. In the past, inorganic flocculants were used in water plants, but the dosage was large, resulting in a bad effect of increasing the amount of sludge. Using anionic polyacrylamide as flocculant, the dosage is 1/50 of inorganic flocculation, but the effect is several times, even dozens of times, that of inorganic flocculant. It is better to use cationic polyacrylamide in combination with river water with serious organic pollution. Papermaking aids: In the papermaking industry, it can be used as a clarification, retention aid, filter aid, and paper dry and wet strength enhancer for caustic soda. Used as a clarifying agent for sugar juice in the sugar industry. Used as an additive and binding agent in aquatic feed.
As the cost of producing oxygen continues to drop, pure oxygen aeration method is widely used. (2) Deep water aeration method. Increasing the depth of the aeration tank can increase the pressure of the pool water, thereby increasing the solubility of oxygen in the water, and the dissolution rate of oxygen is also correspondingly increased. Therefore, the dissolved oxygen in the water of the deep water aeration tank is higher than that of the ordinary aeration tank, generally Increase the pool depth from the original 4m to about 10m. (3) Jet aeration method. The mixed liquid composed of sewage and sludge passes through the ejector, and the negative pressure is generated due to the high-speed jet, so that a large amount of air is inhaled, and the air and the mixed liquid are fully contacted, which improves the oxygen absorption rate of the sewage, so that the efficiency of the treated sewage is obtained. improve. 4) Adding chemical coagulant and activated carbon method. Adding chemical coagulant and activated carbon in the aeration tank of the activated sludge method is equivalent to the physical and chemical treatment at the same time as the biochemical treatment. Activated carbon can also be used as a carrier of microorganisms and has the effect of assisting the sedimentation of solids. The removal rate of BOD and COD is improved, and the water quality is improved.
The polyacrylamide molecule has positive genes, has strong flocculation ability, less dosage, and obvious treatment effect. It has good solubility and high activity. The alum flower formed by agglomeration in the water body is large, and the sedimentation is fast. The purification capacity is 2-3 times greater than that of other water-soluble high-molecular polymers. It has strong adaptability and is less affected by the pH value and temperature of the water body. After purification of the raw water, it reaches the cited water standard. After the treatment, the suspended particles in the water achieve the purpose of flocculation and clarification, which is conducive to ion exchange treatment and the preparation of high-purity water. The corrosiveness is small, the operation is simple, and the labor intensity and working conditions of the process can be used.
