Embodiment 1

[0029] Embodiment 1 Prepare coagulant 1 with the method of the present invention

[0030] Prepare coagulant with the method of the present invention, step is as follows:

[0031] a. Add baking soda and soda ash to the water and stir for 5 minutes to adjust the pH of the solution to 8;

[0032] b. Add modified starch to the solution in step a, stir for 10 minutes, and adjust the pH of the solution to 5;

[0033] c, add modified chitosan towards step b solution, stir for 15min, until forming a stable suspension;

[0034] d. Add organically modified bentonite to the suspension in step d, stir for 6 hours, adjust the pH of the solution to 7, and prepare a new clean and environmentally friendly coagulant finished product 1 after bagging.

[0035] The composition of adding each raw material is: organically modified bentonite 15%, modified chitosan 20%, modified starch 12%, soda ash 5%, baking soda 2%, water 46%.

Abstract

The invention belongs to the field of sewage treatment and particularly relates to a novel clean environment-friendly coagulant and a production method thereof. Given the problems of slow coagulation, bad viscous dissipation effect, water pollution and the like of existing coagulant, the invention provides a novel clean environment-friendly coagulant and a production method thereof. The novel clean environment-friendly coagulant consists of the following components in percentage by weight: 10-15% of organic modified bentonite, 15-20% of modified chitosan, 10-12% of modified starch, 3-5% of sodium carbonate, 1-2% of baking soda and the balance of water. The production method comprises the following steps: sequentially adding the baking soda, sodium carbonate, modified starch, modified chitosan and organic modified bentonite into the water; and adjusting the pH to obtain the novel clean environment-friendly coagulant. In the invention, the coagulation speed of the coagulant is high, the viscous dissipation effect is good, and water pollution is avoided; and moreover, the production raw materials are easily available, the operation is easy, and the production cost is saved.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a novel clean and environment-friendly coagulant and a production method thereof. Background technique [0002] At present, in the spraying process of various car body shells such as automobiles and motorcycles, engines, and various electrical appliance shells, only about 50-70% of the paint sprayed by manual or robotic spray guns will fall on the required spraying surface. In other words, about 30-50% of the paint cannot be sprayed on the shell or is wasted. This part of the wasted paint is generally called overspray paint. Effective and timely treatment of overspray paint is an important link to ensure the smooth progress of the painting process. This is because: for oil-based paints, oversprayed paint adheres in the circulating water tank, pipes and pump body of the spray booth, causing blockage in severe cases; for water-based paints, oversprayed paint causes a la...
