How polymer flocculant was developed into the mainstream of the domestic pharmaceutical? How polymer flocculant was developed into the mainstream of the domestic pharmaceutical? Polymer flocculant is undoubtedly the focus of the current research of various departments, which is why? Due to its advantages of adaptability, non-toxicity, and double efficiency and relatively low cost compared to the traditional flocculants, it has gained wide attention in recent years and is gradually being developed into a mainstream pharmaceutical agent in the coagulation process. At present, the most popular flocculants on the market are: polyaluminum chloride, high-efficiency composite coagulant, polysilicic acid series coagulant, polyacrylamide series flocculant, flocculation decolorant, degreasing flocculant (oil-water separating agent) Sterilization algicide, solid active bromine sterilization algaecide, high effective cationic organic flocculant, cationic flocculant, polyferric sulfate ... Among them, polyaluminum chloride is the most mature industrial production technology, the highest efficiency, the most widely used Inorganic polymer flocculant variety. At the same time, with PAC products as the basic raw material, but also derived a variety of series can be prepared for different water treatment complex inorganic polymer flocculant. Such as PAC, ferrosilicon and organic composite flocculants. Although a large number of coagulation practices proved that the PAC flocculant coagulant performance than conventional aluminum coagulant increased by 2 to 3 times. However, there is a lack of comprehensive and in-depth scientific verification and theoretical diagnosis of why these new types of pharmaceuticals are outstandingly efficient. The general understanding and handling methods are still stuck with the concept of traditional coagulants or subjective inference, and there is no direct experimental verification. In fact, in the application of polyaluminum chloride, from the morphological distribution and transformation rules, polymerization control parameters and preparation conditions, morphological transformation and stability after dosing, flocculation mechanism and efficiency of efficient coagulation, and application process technology And many other aspects, are different from the traditional coagulant, these issues can only be a thorough and systematic study in order to get a more accurate answer, while promoting the further improvement of these new agents and expand its scope of application. Efficient composite flocculant is a new type of innovative development based on the original inorganic polymer flocculant. It has the characteristics of high efficiency, high quality and low price, fast reaction, compact flocculation and fast settling. Than the traditional products with significant turbidity, nitrogen and phosphorus removal and oil, COD and BOD and other functions.
