Oxidation ditch and MBBR integrated sewage treatment equipment

Abstract

The invention discloses oxidation ditch and MBBR(Moving Bed Biofilm Reactor)integrated sewage treatment equipment. The oxidation ditch and MBBR integrated sewage treatment equipment comprises a horizontal shell, a water inlet and a water outlet, the water inlet and the water outlet are formed in the horizontal shell respectively, the horizontal shell is provided with a main partition plate and divided into at least three cabins in the length direction, and an A/O area is communicated with a settling area through a pipeline; an overflow opening/water passing opening is arranged on the main partition plate between the settling area and a water outlet area. The oxidation ditch and MBBR integrated sewage treatment equipment is characterized in that the oxidation ditch and MBBR integrated sewage treatment equipment is from left to right sequentially provided with at least one cabin as the A/O area, at least one cabin as the settling area, and at least one cabin as the water outlet area, a partition plate is arranged in the A/O area and divides the A/O area into an anoxic tank and an aerobic tank in the length direction of the horizontal shell, an overflow opening/water passing opening is formed in the partition plate, an aeration device is arranged in the aerobic tank, and a branch partition plate is arranged in the anoxic tank in the length direction of the horizontal shell and divides the anoxic tank into two cavities communicating end to end, the two cavities are respectively an anaerobic section and an anoxic section, an oxidation ditch circulation channel is formed, and thewater inlet is positioned at the anaerobic section of the anoxic tank.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to the field of rural sewage treatment. Background technique [0002] Most of the integrated rural sewage treatment equipment in the prior art is made of plastic material, with low strength, difficult transportation and installation, and high manpower and material costs. Moreover, the current integrated rural sewage treatment equipment has poor denitrification effect, and the quality of effluent water is poor. Often the total nitrogen content is too high, which can easily cause secondary pollution to the river. Contents of the invention [0003] The purpose of the present invention is to provide a small footprint, low equipment cost, convenient transportation, combined oxidation ditch process, secondary sedimentation tank process, and fiber membrane filtration process, strong resistance to water flow impact, good denitrification effect, and convenient later maintenance. An integra...
