Treatment process: MBR integrated sewage treatmentequipment characteristics:

1.high removal rate of nitrogen；

2.the shock resistance capacity；

3.The sludge age is long and theamount of excess sludge is little;

4.the system is automatic control,easy operation and management;

5.high removal rate of pollutants,water quality is good, can be used directly;

6.hydraulic retention time (HRT)and sludge retention time (SRT) complete separation;

7.biological concentration is upto 8-12g/l, Volumetric loading,Small footprint
