[0002] Wastewater treatment: the process of purifying wastewater to ensure that it meets the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people. In particular, in the printing and dyeing industry, in order to protect the water resources environment, it is particularly important to strictly purify the wastewater generated by printing and dyeing.

This scheme has a simple structure, convenient operation, good treatment effect, and is environmentally friendly and practical. However, the structure of this utility model is relatively complex, and the area required for its use is large, and the sewage treatment efficiency is low, which is not convenient for ensuring the economic benefits and operating efficiency of sewage treatment operations. For this reason, we proposed a multi-stage sewage treatment device for a printing and dyeing workshop, which saves land and improves sewage treatment efficiency, thereby improving the economic benefits and practicality of the device.
