Problems solved by technology

However, due to the strong acidity of titanium sulfate itself, and when used as a flocculant, Ti 4+ Hydrolysis releases a large amount of H + , these factors lead to the low pH of the coagulation effluent, which has a certain impact on the subsequent utilization or further treatment of the effluent

Abstract

The invention relates to a polymeric titanium sulfate (PTS) inorganic polymeric flocculant, and a preparation method and an application of the flocculant. The PTS inorganic polymeric flocculant is prepared by taking a titanium sulfate solution and sodium hydroxide as raw materials and dropping sodium hydroxide into the titanium sulfate solution; a preset alkalization degree is 0.1-5.0; after the dropping is finished, the titanium sulfate solution and sodium hydroxide are stirred for 1.5-5h. The flocculant has the advantages of good product stability, strong adsorption bridging ability for colloidal substances, good flocculation effect, wide application range, small generated sludge quantity and the like, can be widely applied to the fields of water supply, waste water treatment, papermaking, textile printing and dyeing, daily-use chemical industry and the like, and has a good water treatment effect. The method has the characteristic that a production technique is simple, economical and rapid.

Description

(1) Technical field [0001] The invention relates to a polymeric titanium sulfate inorganic polymer flocculant (PTS) and a preparation process thereof, belonging to the technical field of environment and chemistry. (2) Background technology [0002] Coagulation and sedimentation are the most widely used and low-cost key technical links. The effect of coagulation treatment depends to a large extent on the quality of flocculants. Therefore, new and efficient water treatment chemicals have become the The pillar industry that focuses on 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...
