This case study introduces how Environmental Protection Technology City Industrial Wastewater Treatment Plant Project uses our factory's high-efficiency dissolved air flotation to treat oily wastewater, such as machining and cutting fluids. After treatment, the effluent quality was significantly improved, the effluent indexes of animal and vegetable oils and petroleum reached about 1 mg/L, and the total phosphorus removal rate was over 98%.
Yancheng Dongtai Bizhiyuan Water Purification Co., Ltd. Industrial Wastewater Treatment Plant. After being treated by flotation equipment, the effluent indicators meet the following requirements: SS≤ 10 mg/L, TP≤ 1.8 mg/L. The SS removal rate is ≥90%, and the TP removal rate is ≥70%.
Although automobile painting wastewater has high water quality complexity and is difficult to treat, it is necessary to classify, collect, and pre-treat wastewater according to quality as long as the characteristics of the wastewater are understood and appropriate treatment processes are adopted.
The wastewater generated during the coating production process of the enterprise has the characteristics of many types of pollutants, high concentration, complex composition, intermittent discharge of wastewater and irregular discharge time, poor biodegradability, etc. Reasonable selection of wastewater treatment methods and design of treatment processes that meet the requirements of the enterprise according to different process characteristics in accordance with local conditions can improve the treatment efficiency of wastewater, reduce treatment costs and shorten the treatment cycle.
