Background

The sewage is lifted from the regulating tank through the water inlet pump of the membrane biochemical reactor, and a bag filter with the filtering level of 600-800um is arranged in front of the water distribution system to prevent particulate solids from entering the subsequent treatment unit for protecting the subsequent membrane treatment unit. The external membrane biochemical reactor is provided with biological denitrification function, namely, consists of denitrification, nitrification and external ultrafiltration units. The BOD, heavy metals, suspended matters and the like of the ultrafiltration effluent treated by the external MBR reach the discharge standard. However, COD formed by the organic matters difficult to be biochemically degraded still can exceed the standard, and the effluent does not contain suspended matters, so that the ultrafiltration effluent is deeply treated by Nanofiltration (NF) to remove the organic matters difficult to be biochemically degraded. In actual operation, the ultrafiltration clear liquid treatment capacity of the nanofiltration system can be determined according to the water quality condition of the effluent. If the ultrafiltration effluent water quality is good, the reduction of the ultrafiltration clear liquid treatment capacity of the nanofiltration system can be considered, and meanwhile, the yield of nanofiltration concentrated solution is reduced, so that the running cost can be further reduced. Thus, the nanofiltration concentrate is handled by external transport.

In sewage treatment, the production sewage from in the garden sewage collection tank is lifted to the equalizing basin through the elevator pump, because the solid particles that rubbish compression liquid contains are more, in order to avoid solid particles to get into the equalizing basin, consequently set up the slagging-off preliminary treatment before the equalizing basin, the solid particles that the particle diameter is greater than 1mm is got into through pretreatment systems before the sewage gets into the equalizing basin, granule returns to the filter screen and causes the jam when handling the solid particles in the sewage in prior art, thereby lead to subsequent filtration efficiency to reduce, lead to the unable normal operating of complete processing system, greatly reduced the maintenance cost and the life of equipment.
