Problems solved by technology

The composition of this formula is complex, and strong oxidants and adsorbents are mainly used to eliminate pollution sources in water bodies. However, calcium hypochlorite is extremely corrosive, has great danger and instability, and has high operating process conditions and costs. Moreover, the treatment efficiency of the sewage treatment agent is limited, and the treated water has relatively high hardness, which is not suitable for direct recycling

Abstract

The invention relates to a sewage treatment composite medicament and a preparation method thereof, and belongs to the technical field of sewage treatment. The technical scheme adopted is: a sewage treatment composite medicament comprises, by mass, 85-94% of bentonite, 0.5-2.5% of sodium tartrate, 0.5-2.5% of carboxyethyl thiosuccinic acid, 0.4-1.6% of chitosan and 4-9% of stearate, wherein the bentonite is inorganic modified bentonite. The formulation of the medicament has the advantages of simple structure and low cost. The product used or sewage treatment is environmental and safe, has goodadsorption effect and has effects of corrosion inhibition, scale inhibition and bacteriostasis.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a compound agent for sewage treatment and a preparation method thereof. Background technique [0002] With the rapid development of modern industry, the problem of water pollution has become a global problem. Effectively treating waste water and repairing polluted water bodies, and making them reusable water resources, in the rapid economic development and the per capita fresh water resources are very low. The moment of shortage is very urgent and important. Water treatment agent is a necessary chemical agent in the process of industrial water, domestic water, and wastewater treatment. It is mainly used to remove suspended solids in water, deodorize and decolorize, inhibit bacteria or sterilize, soften water quality, and inhibit scale formation. It is even a key factor in determining the effectiveness of water governance. According to the functional characteristics of ...
