This refers to the sewage treatment agent polyacrylamide especially in the choice of this part of the sewage treatment sludge dewatering agent most critical, there is a lot of uncertainty, things often happen mutation, often matching good medicine, but because the field of water some Chengfa points or sludge to produce qualitative changes occur, leading to selection of good agents fail or weaken the effect of such a result, they have to go back and re-extracted samples of effluent to do with type test, which requires not just pharmaceutical suppliers is to provide products, but also have good after-sales service, under normal circumstances, with a type of good medicine is still relatively stable. Currently on industrial solid-liquid separation process is generally done to polyacrylamide flocculant used, including sedimentation, clarification, concentration and sludge dewatering process industry applications is also more widely, depending on the source water is mainly divided into two types: urban sewage and industrial wastewater. 1. Municipal Wastewater: refers collectively urban sewage discharged into the sewage system, but also include municipal wastewater sewage and industrial wastewater, urban sewage in the selection of polyacrylamide used as a flocculant, generally using cationic polyacrylamide, ion degree is generally about 40% ~ 60%, of course, depending on, have a concrete analysis of specific issues of water quality. 2. Industrial waste: According to the industrial waste contained in the main pollutants to the classification of the chemical nature of the case, mainly divided into: organic pollutants containing mainly organic wastewater containing inorganic contaminants inorganic wastewater, and containing organic and Hybrid inorganic waste, waste water and contaminated cooling water is only heated containing radioactive substances as well as heavy metal waste. For example: food or waste oil processing process is organic waste, and wastewater and electroplating wastewater is an inorganic mineral processing waste. According to industrial processing object classification, it can be divided into: metallurgical waste, textile waste, wastewater, wastewater, wastewater, refinery wastewater, mineral industry, dyeing industry and the sugar industry. Urban sewage and industrial wastewater treatment method commonly used activated sludge, biological sludge is often highly hydrophilic colloids, organic content, is extremely difficult to dehydration. Treatment with cationic polyacrylamide, with less dehydration, high efficiency, easy separation. Alcohol plant wastewater, brewery waste water, monosodium glutamate factory wastewater, wastewater sugar mills, meat plant wastewater, beverage plant wastewater, textile printing and dyeing wastewater. Cationic polyacrylamide than using anionic polyacrylamide, nonionic polyacrylamide or inorganic effect several times or several times higher. Because this type of waste generally has a negative charge. Polyacrylamide selection is mainly based on the charge of wastewater quality of different types to be, according to the water quality characteristics to choose cationic polyacrylamide, anionic polyacrylamide, or zwitterionic polyacrylamide, the process is generally from experiments small test chamber, large manufacturers try to finalize the product selection, to analyze specific issues. Whatever the quality of what the industry, the election of the model is the most critical, when mutated incidents have occurred, once changed, we need to calmly, do not just look at the problem itself, to find solutions, itself polyacrylamide Selection is a highly experimental procedure.
