Problems solved by technology

[0005] Inorganic flocculants are cheap, but they will have adverse effects on human health and the ecological environment; although organic polymer flocculants are used in a small amount, the scum output is small, the flocculation ability is strong, the flocs are easy to separate, and the effect of removing oil and suspended matter is good , but the residual monomers of this type of polymer have "three-caused" effects (causal, carcinogenic, and mutagenic), thus limiting its application range

Abstract

The invention relates to a composite flocculant used in a spinning sewage treatment process. The composite flocculant consists of the following raw materials in parts by weight: 10-20 parts of thalluses of composite type flocculus producing bacteria F2 and F6, 15-20 parts of aluminium hydroxide gel and 3-10 parts of chitosan, wherein a weight ratio of F2 to F6 in the thalluses of composite type flocculus producing bacteria is (1-3) to 1. The composite flocculant is high in activity, safe and non-toxic and free of secondary pollution.

Description

technical field [0001] The invention relates to a composite flocculant used in textile sewage treatment process and belongs to the field of textile technology. Background technique [0002] Textile sewage comes from the washing process of textile factories, which contains high BOD, COD, total dissolved solids, and organic substances that are difficult to biodegrade, such as: some softeners, surfactants, etc. Textile sewage has the characteristics of large water volume, complex composition, and serious environmental pollution. Flocculation technology is an important means of treating sewage and wastewater. [0003] According to its chemical composition, flocculants can be generally divided into two types: inorganic flocculants and organic flocculants. Inorganic flocculants include inorganic coagulants and inorganic polymer flocculants; organic flocculants include synthetic organic polymer flocculants, natural organic polymer flocculants and microbial flocculants. There are...
