Abstract

The invention discloses a compound aeration device for controlling gradient dissolved oxygen distribution, and belongs to the technical field of sewage treatment. The compound aeration device comprises a sewage treatment device body, wherein access holes are formed in the top of the sewage treatment device body; a water inlet pipe is arranged at one end of the sewage treatment device body; a wateroutlet pipe is arranged at the other end of the sewage treatment device body; through the arrangement of a first separation plate, a second separation plate and a third separation plate inside the sewage treatment device body, the inside of the sewage treatment device body is separated into an anoxic region, an anaerobic region and an aeration region; the aeration region is filled with nanometermodified flexible fillers; and a micropore aeration air inlet pipe and a perforated air inlet pipe are arranged on the side edge of the aeration region. By using a compound aeration method of combining a perforated pipe and a micropore aeration pipe, sufficient mass transfer, high oxygen charging efficiency and good denitrification effects can be ensured; the nanometer modified flexible fillers have developed pore structures, so that the dissolved oxygen gradient is gradually formed from the surface to the inside; short-cut simultaneous nitration and denitrification is realized; the denitrifying efficiency of a system is improved; and outlet water is enabled to stably reach standards.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a compound aeration device for controlling gradient dissolved oxygen distribution. Background technique [0002] Because the biological process has the advantages of low cost, good effect, no need to add additional chemicals, small footprint, simple operation and maintenance, and convenient operation, such as A 2 / O, A / O, A 2 o 2 , inverted A 2 / O and other processes are widely used in urban or rural domestic sewage treatment processes. However, due to the difficulty in maintaining stable water quality, low organic matter content in sewage, and low carbon-to-nitrogen ratio sewage are very common. In some southern regions, the carbon-to-nitrogen ratio of domestic sewage is only 2 to 3. At the same time, under the condition of controlling certain parameters, it is difficult to improve the denitrification effect, and the total nitrogen in the effluent often exceeds the ...
