Multifunctional wastewater treating agent and application thereof in wastewater treatment process

Abstract

The invention discloses a multifunctional wastewater treating agent and application thereof in wastewater treatment process. The process comprises the steps of 1), first, collecting wastewater in a stainless steel barrel; 2), second, adding the multifunctional wastewater treating agent into wastewater in the stainless steel barrel, and stirring for 5-10 min; 3), then, stopping stirring, standing, flocculating, and precipitating; 4), then, discharging and recycling supernate; 5), finally, press-filtering precipitate, packing filter residue, and charging wastewater into the stainless steel barrel for cyclic treatment. The multifunctional wastewater treating agent comprises cationic polyacrylamide, anionic polyacrylamide, nonionic polyacrylamide, polyaluminum chloride, polyferric sulfate, basic aluminum chloride, hydroxypropyl methyl cellulose, sodium hyposulfite, glucose, corn starch and sodium benzoate. By optimizing the formulation ratio of the multifunctional wastewater treating agent, it is possible to subject the wastewater to treatments at a time such as decoloring, flocculating, precipitating, COD and ammonia nitrogen reducing, and the multifunctional wastewater treating agent is very worthy of marketing.

Description

technical field [0001] The invention relates to the technology in the field of sewage treatment, and in particular provides a multifunctional sewage treatment agent and its application in sewage treatment process. Background technique [0002] In order to remove the color of industrial sewage, the traditional process uses a variety of chemicals to treat them in stages. The process is complicated, the operation is difficult, the dosage is controllable, the decolorization effect is unstable, and the speed is slow; the raw materials of the chemicals should be industrial raw materials. , It will cause secondary pollution to the environment after treatment; the treatment process occupies a large area and increases the cost of sewage treatment. Traditional liquid sewage treatment agents have high requirements on the water body of sewage, and at the same time need to be combined with other chemical treatment agents to achieve the decolorization effect, but the effect is not obvious...

[0002] In order to remove the color of industrial sewage, the traditional process uses a variety of chemicals to treat them in stages. The process is complicated, the operation is difficult, the dosage is controllable, the decolorization effect is unstable, and the speed is slow; the raw materials of the chemicals should be industrial raw materials. , will cause secondary pollution to the environment after treatment; the treatment process uses a large area and increases the cost of sewage treatment

Traditional liquid sewage treatment agents have high requirements on the water body of sewage, and at the same time need to be combined with other chemical treatment agents to achieve the decolorization effect, but the effect is not obvious, the speed is slow, the decolorization is not complete, the treatment function is single, and the controllability of the dosage is poor; the workload is large , Complicated operation; In addition to the high packaging cost and inconvenient transportation of liquid products, the quality and fluidity of the product itself is unstable and the shelf life is short
