printing and dyeing waste water treatment The equipment is specially used to treat the wastewater generated by the printing and dyeing industry, which is an industry with large water consumption in the textile industry. The wastewater has the characteristics of large water volume, high chroma, complex composition, high pH value and difficult biodegradation. These characteristics make printing and dyeing wastewater recognized as difficult to treat industrial wastewater.
The pollutants contained in the printing and dyeing wastewater mainly come from the fabric fiber itself and the dyes and chemicals used in the processing process, including dyes, sizes, auxiliaries, oils, acids and alkalis, fiber impurities and inorganic salts. Among these pollutants, the nitro and amino compounds in the dye structure and heavy metal elements such as copper, chromium, zinc and arsenic have greater biological toxicity and seriously pollute the environment.
Printing and dyeing wastewater treatment equipment The process features of the product mainly include:
1. Biological contact oxidation process: this process has the characteristics of small size, strong adaptability to water quality, good impact load resistance, stable effluent quality, and no sludge bulking.
2. Large specific surface area of filler: microorganisms are easy to form and remove membranes. Under the same organic load conditions, the removal rate of organics is high, stable and reliable, without the need to add chemicals, saving subsequent costs and reducing operating costs.
3. Hydrolysis acidification: it can effectively reduce the chromaticity of sewage, improve the biodegradability of sewage, reduce the load of subsequent treatment, and greatly reduce the dosage of decolorizing agent for later dosing, saving investment.
The selection of printing and dyeing wastewater treatment equipment needs to consider many factors, such as production process, dyes and chemicals used, textile types and management level. Because the products of each factory are constantly changing, and the concentration of pollutants in wastewater changes and fluctuates frequently, it is very important to select appropriate treatment equipment and technology.
