Municipal Wastewater Treatment
Characteristics of
Municipal Wastewater
Municipal Wastewater
The quality of municipal wastewater is relatively stable, but the water volume fluctuates greatly. Due to the residential water peak period, it is often in the low load operation mode, and some water quality will have low influent COD and insufficient carbon source. In addition, for projects where rainwater and sewage are not diverted, the water volume affected by weather conditions will increase sharply, and the lack of nutrients in the water will lead to sludge loss.
Most of the park's wastewater is directly discharged by enterprises or reaches the discharge standard after treatment by enterprises. Its quality changes greatly, and the inffluent water volume is greatly affected by the production and drainage cycle of enterprises. In general, there are many refractory substances in the water, the composition is complex, the biodegradability is poor, and the requirements for the impact load resistance of the system are high.

An Industrial Park Project in Jiangsu Province
Outline of the Facility：
An industrial park project in Taizhou with a 4800 ³/ D treatment capacity, which was equipped with a total of 20 groups of PE150II-160-3S membrane modules ,had been working since 2021.
Performance：
The influent COD concentration of the biochemical tank is 100-150mg/l, and the ammonia nitrogen is 15-25mg/l. The sludge concentration of the MBR tank is stable at about 6000-8000mg/l. The effluent COD is less than 50mg/l, and the ammonia nitrogen is less than 5mg/l. Cleaning and maintenance are carried out every 3 months with a stable membrane operation.
