Abstract

The invention discloses a preparation method of a water treatment composite. The water treatment composite is prepared from, by weight, 33-37 parts of a nanotube-nano-silver-polyaluminium chloride material, 15-20 parts of polymeric flocculant, 5-12 parts of tripotassium phosphate and 6-11 parts of magnesium sulfate. The preparation method has the technical advantages that the removal effect on organic pollutants is good, the preparation method is simple, and the preparation process is easy to control; the water treatment composite is free of toxin and pollution and can be naturally decomposed in water, and secondary biochemical pollution is greatly lowered; TDS, the electrical conductivity and COD of wastewater can be obviously lowered, and the times of recycling of papermaking wastewater are greatly increased.

Description

technical field [0001] The invention relates to a preparation method of a water treatment composite material. Background technique [0002] With the rapid improvement of my country's industrialization of production and living standards, the annual discharge of production wastewater and domestic sewage is also increasing rapidly in series. Efficient and safe treatment of these wastewater and sewage is a challenge for the coordinated development of environmental protection and resource utilization. It is also one of the difficulties that many chemical companies urgently need to get rid of. [0003] High-concentration organic wastewater generally refers to wastewater with COD above 2000mg / L discharged from papermaking, leather and food industries. These wastewaters contain a large amount of organic matter such as carbohydrates, fats, proteins, cellulose, etc. If they are discharged directly, they will cause serious pollution. [0004] Since it is difficult to meet the economic...
