Composite material for absorbing and treating printing and dyeing industry wastewater

Abstract

The invention discloses a composite material for absorbing and treating printing and dyeing industry wastewater, which comprises the following components in parts by weight: 10-20 parts of emulsion, 5-9 parts of titanium white, 10-20 parts of humectant, 10-20 parts of quartz sand, 10-13 parts of wood fiber, 5-8 parts of hollow glass microsphere, 5-8 parts of graphite powder, 10-15 parts of kaolin, 0.3-0.5 part of thickener, 0.1-0.3 part of wetting agent, 0.3-0.5 part of dispersant, 50-60 parts of oyster shell powder, 3-9 parts of phosphate, 5-14 parts of concentrated hydrochloric acid, 14-26 parts of ethanol, 5-16 parts of ammonia water, 3-6 parts of gallic acid, 2-6 parts of citric acid, 1-6 parts of kieselguhr and 3-8 parts of open-pore expanded perlite. By using a natural calcium material as the substrate, the material has the advantages of cheap raw materials, no pollution, low preparation cost, high economy and high efficiency, reduces the environmental load, can efficiently treat dyeing wastewater and is simple to operate.

Description

technical field [0001] The invention relates to a composite material for absorbing and treating printing and dyeing industrial waste water. Background technique [0002] The textile printing and dyeing industry is a large discharge of industrial wastewater. According to incomplete statistics, the national discharge of printing and dyeing wastewater is 36 million tons per day. Wastewater contains a variety of dyes. The wastewater is characterized by high concentration of organic matter, complex components, poor biodegradability, high and changeable chroma, and large changes in water quality and quantity. It is a difficult industrial wastewater to treat. Therefore, it is of great significance to study the treatment of printing and dyeing wastewater to protect the ecological environment and human health. Because printing and dyeing wastewater generally has high biological toxicity and carcinogenicity, physical or chemical methods are commonly used in engineering to treat it, s...

Problems solved by technology

The decolorization effect of these methods is not very good, and has the disadvantages of high cost and short time limit.

Studies in recent years have found that adsorption is an effective method for removing such pollutants, because it is low in cost, easy to operate, insensitive to toxic substances, and can completely remove pollutants in dilute solutions. At the same time, it is necessary to solve the problem of pollutant transfer after adsorption
