Because of the high concentration of printing and dyeing wastewater, the color of the large color, the use of chemical and biochemical methods are often difficult to meet the requirements of the effluent quality, and the biochemical method is needed.. The main body is the biological contact oxidation process for wastewater treatment process.
The process flow is: grid conditioning pool - hydrolysis acidification pool - biological contact oxidation pond - two sedimentation tank (vertical flow sedimentation tank) - sludge thickening pool - disinfection pool - cleaning tank

First, the printing and dyeing wastewater through the grille, remove some of the more likely to plug the water pump and pipe valve of the thicker suspended solids. With and into the adjustment pool, with the temporary storage of sewage, and set aeration equipment, so that the water quality of the uniform. Subsequently, the pump is the wastewater into the hydrolysis acidification pool, the pool used to degrade polymer organics, improve the biodegradability of wastewater. Biological contact oxidation pool is the main part of the whole process, the biological contact oxidation process is between activity between sludge and biological aerated filter two biological sewage treatment technology, both activated sludge process and biofilm process characteristics. Finally, the sludge concentration of Sinotrans, water disinfection discharge after treatment or further processing.
This process has the advantages of compact structure, convenient operation, low impact load, small amount of sludge, high degree of automation and low labor intensity..
Sewage plant layout is reasonable, the focus is outstanding, the area is small, the environment is beautiful, closely around the concept of environmental protection.
