Abstract

The invention relates to an integrated advanced wastewater treatment device and process. A sludge reflowing pipe is arranged at the bottom of a settling region, wherein one end of the sludge reflowing pipe is connected with a flocculation region, a sludge discharging pipe is arranged at the other end of the sludge reflowing pipe, and a filter cloth filtering region and a disinfecting region are arranged up and down and are adjacent to the settling region. Wastewater enters a mixing region through a wastewater inlet pipe, enters the flocculation region through a first water passing hole after being mixed, and enters the settling region through a second water passing hole after being flocculated; supernate overflows through an effluent weir after sludge and wastewater are separated through settling in the settling region, and enters the filter cloth filtering region after passing through a grating plate, effluent enters the disinfecting region from meshes in the bottom through a wastewater collecting tank after being filtered, and discharged through a wastewater outlet pipe through a third water passing hole after being disinfected, and a sludge part reflows to the flocculating region through a sludge reflowing pipe, and is partially discharged through the sludge discharging pipe. The process provided by the invention is reasonable in procedures; the device is compact in integrated design, saving in occupation area, less in head loss and less in chemical adding amount.

Description

technical field [0001] The invention belongs to the field of sewage treatment and relates to a sewage treatment device, in particular to an integrated sewage advanced treatment device and a process thereof. Background technique [0002] With the continuous development of sewage treatment technology, the sewage after secondary biochemical treatment has basically met the discharge requirements, and only needs to carry out advanced treatment on some water quality indicators to meet the standard discharge or reuse. The selection of sewage advanced treatment process is very different due to the difference in treatment objectives and effluent water quality. In a broad sense, the scope includes denitrification and phosphorus removal, removal of suspended solids, removal of organic matter, and disinfection. In the selection of many advanced treatment processes, the "coagulation-sedimentation-filtration-disinfection" process combination is favored because of its stable operation and...
