System and process that uses a Biological reactor with membrane with granular activated carbon suspension includes a structural feature to protect the membrane of abrasion due to Coal

摘要

1. An industrial wastewater treatment system, which uses a biofilm reactor to reduce the concentration of biorefractory compounds and / or biological inhibitors in the treated wastewater. Its characteristics are as follows: an air tank for reinjection of industrial wastewater flow; Including a wastewater discharge port, a population of one or more active microorganisms digesting waste in a discharge tank; 1. One or more particle activated carbon input points are associated with the reluctant gas tank to input the particle activated carbon into the reluctant gas tank;1. The granular activated carbon needs to be suspended in the reluctant oil tank to absorb the biologically resistant compounds and / or biologically inhibit the residual water flow on its surface, and there are active bacteria and microorganisms to absorb the residues in its pores; 1. Membrane operating system, which contains one or more diluents at the bottom of one or more diluent tanks. The membrane operating system receives a mixed gas cylinder and discharges the treated wastewater from the diluent tank;And a fine filter grid or ion separation system, placed in the reluctant air tank, so as to keep the granular activated carbon in the reluctant air tank, mix alcohol, and prevent at least most of the granular activated carbon from entering the air tank of the membrane operating system,
