Abstract

The invention relates to the technical field of environmental pollution control and municipal-engineering wastewater treatment. The invention provides a deep treatment device for municipal wastewatertreatment upgrading. The device includes a denitrifying biological filtering tank, a nitrifying biological filter tank or an aerated biological filter tank, a magnetic coagulation sedimentation device, a filter-cloth filter tank or a turntable filter tank device and a disinfection tank. The denitrifying biological filtering tank is provided with a matched carbon source feeding device, and the magnetic coagulation sedimentation device is provided with a matched separator (namely a high shearing machine). The device has the multi-level deep filtering functions owing to the denitrifying biological filtering tank, the nitrifying biological filtering tank (or aerated biological filter tank), the magnetic coagulation sedimentation device and the filter-cloth filter tank (or the turntable filtertank), and thus can effectively remove various pollutants such as CODCr, BOD5, ammonia nitrogen, total nitrogen, total phosphorus, suspended solids and other pollutants in wastewater.

Description

technical field [0001] The invention relates to the technical field of environmental pollution control and municipal engineering sewage treatment, in particular to an advanced treatment process and device for urban sewage treatment. Background technique [0002] In recent years, my country's sewage treatment plants have continued to upgrade their standards. Some sewage plants still have certain problems after upgrading and upgrading, and some sewage treatment plants that have been upgraded and transformed have problems with effluent exceeding the standard. For example, a sewage treatment plant has added high-efficiency sedimentation and filter cloth between the secondary sedimentation tank and the disinfection tank. Filter (or rotary disc filter) technology, effluent suspended particulate matter (SS), ammonia nitrogen, total phosphorus, etc. can all meet the first-class A standard, but sometimes CODCr and total nitrogen slightly exceed the standard, and the reclaimed water c...
