Abstract

The invention relates to a titanium tetrachloride-poly dimethyl diallyl ammonium chloride inorganic-organic compound flocculant and a preparation method thereof. According to the compound flocculant, the content of Ti(titanium) is 6.80-6.98wt%, and the content of polydimethyl diallyl ammonium chloride is 1.74-4.25wt%. The preparation method of the compound flocculant comprises the following steps of: using titanium tetrachloride solution and polydimethyl diallyl ammonium chloride as raw materials; mixing the PDMDAAC (poly dimethyl diallyl ammonium chloride) according to the weight ratio of Ti(titanium) to the PDMDAAC equal to 4-10:1; and, at the normal temperature, blending and reacting to obtain the product. The flocculant combines the advantages of the PDMDAAC and the titanium tetrachloride, has good comprehensive property, and is widely applied to the fields such as the water supply industry, the wastewater treatment industry, the paper-making industry, the textile dyeing industry, and the daily chemical industry. When the adding amount of the flocculant is 10-30mg/L, the water treatment effect of flocculant is good.

Description

technical field [0001] The invention relates to titanium tetrachloride and polydimethyldiallylammonium chloride inorganic-organic composite flocculant (TiCl 4 -PDMDAAC) and its preparation process, which belong to the field of environmental and chemical technology. Background technique [0002] Coagulation sedimentation is the most widely used and low-cost key technical link. The effect of coagulation treatment depends to a large extent on the quality of coagulant. The pillar industry that deals with the key development in the field of environmental protection technology is also the basic industry for the innovation and development of water industry and water pollution control engineering technology and equipment. The research and development of inorganic-organic composite water treatment agents will bring profound changes to the water supply industry, water pollution control and water-saving purification, and create a high-efficiency, low-consumption, and low-investment wa...
