Analysis of the Process Characteristics of Printing and Dyeing Wastewater Treatment Equipment

The printing and dyeing wastewater treatment equipment adopts a biological contact oxidation treatment process, which has a smaller volume than the active sludge tank, and the equipment has a stronger ability to treat water quality. The effluent water quality is relatively stable, and the load performance of the pulse machine is good, without the problem of sludge expansion.

The process fillers used in printing and dyeing wastewater treatment equipment have a relatively large specific surface area, making it easier for microorganisms to demold the membrane. Under the same organic matter conditions, their removal efficiency of organic pollutants is higher and more stable. At the same time, there is no need to add other chemicals to the wastewater during the use of printing and dyeing wastewater treatment equipment, which can save some subsequent costs and reduce the operating expenses of the equipment. The dyeing and printing wastewater treatment equipment can effectively reduce the color treatment of wastewater through hydrolysis acidification, improve the biodegradability of wastewater, and also reduce the amount of chemicals used in the later stage, saving costs. The effect of using printing and dyeing wastewater treatment equipment is relatively ideal. After obtaining good water quality for decolorization treatment, the decolorization rate can reach over 99.4%, thus meeting the discharge standards. The printing and dyeing wastewater treatment equipment can effectively treat the remaining sludge, ensuring reliable and stable operation of the equipment. It is more convenient to discharge sludge and reduces human interference. This equipment adopts some unique structures, which can effectively limit the further diffusion of odor. The operation and management process is relatively simple, and operators can adjust the status according to the actual situation to achieve better operating results.

The printing and dyeing wastewater treatment equipment comes into contact with some printing and dyeing wastewater, which has a relatively small amount of water but a high concentration of pollutants, including various pulp decomposition products, pulp, fibers, additives, starch alkali, etc. The overall sewage is alkaline, with a pH value of up to 12, and the upper paddle is mainly composed of starch, which has high COD and BOD values and high biodegradability. The pulp is mainly made of PVA, although the COD is high, the BOD is relatively low, and the biodegradability of the wastewater is relatively poor. This type of printing and dyeing wastewater treatment equipment can be applied to the treatment of various low concentration, medium concentration, and high concentration printing and dyeing wastewater, such as wool dyeing wastewater, knitting dyeing wastewater, silk dyeing wastewater, cotton textile wastewater, chemical fiber wastewater, etc. The treated wastewater can meet the discharge standards and is widely used in various printing and dyeing factories, and is very popular.
