Abstract

The invention discloses a composite flocculating agent and a preparation method thereof. With titanium white waste acid and ferrous sulfate, waste nylon and starch as raw materials, an efficient composite flocculating agent with less charging quantity, high coagulation speed, strong decontamination capability and wide application range is obtained by using a simple one-pot process. According to the invention, wastes are controlled by wastes, wastes are turned into wealth, the environment is improved, a new way is built for recycling and hazard-free treatment of industrial wastes and the composite flocculating agent and the preparation method thereof are beneficial for environmental protection. Through the adoption of the composite flocculating agent and the preparation method thereof, the titanium white waste acid and side product ferrous sulfate can be sufficiently utilized, an environment pollution problem is solved, the added value of the titanium white powder industry can be also effectively increased, the production cost of the flocculating agent and sewage treatment cost are reduced, and very strong economic benefits, environment friendly benefits and social benefits are obtained.

Description

technical field

[0001] The invention belongs to the technical field of waste acid treatment and water treatment agent preparation, and relates to a composite flocculant and a preparation method thereof, in particular to a high-efficiency composite flocculant prepared by using sulfuric acid titanium dioxide waste acid and its by-product ferrous sulfate. Background technique

[0002] With the enhancement of people's awareness of environmental protection, the standard treatment of industrial wastewater and urban sewage has become a top priority. According to the survey, the amount of industrial wastewater treated is less than 20% of the total amount, and urban sewage is only treated experimentally in a few cities for the time being, mainly because of the high cost of treatment. Therefore, it is urgent to develop efficient and cheap wastewater treatment agents. Flocculant is the most important water treatment agent, and its consumption is huge, increasing by a high percentage e...
