Description

Tail water treatment device for aerobic denitrification Technical Field The utility model relates to the technical field of tail water treatment, in particular to a tail water treatment device for aerobic denitrification and denitrification. Background The traditional biological denitrification process needs to be independently provided with an anoxic tank and an aerobic tank to finish denitrification and nitrification processes respectively, and the aerobic denitrification is used as an emerging denitrification technology, most of aerobic denitrification bacteria have heterotrophic nitrification capacity at the same time, so that the removal of organic matters and nitrogen in wastewater can be realized at the same time, an additional anaerobic reactor is not needed, the operation and maintenance cost is low, and the accumulation of nitrate and nitrite is basically avoided in the treatment process. Usually, in the tail water treatment process, some impurities in the tail water are filtered firstly, and the tail water is treated by aerobic bacteria, but after long-term use, more and more impurities are filtered, the tail water can pass through the filtering device quickly and smoothly, a water flow channel is narrowed due to blockage, and the water flow speed is reduced. This means that the amount of tail water that can pass through the filter equipment in unit time reduces, and throughput reduces, and simultaneously, the jam still can make filter equipment to the interception effect of impurity worsen, and some impurity that should filter originally can get into subsequent processing link along with the rivers, has increased the burden of subsequent treatment technology, probably influences the steady operation of whole tail water processing system even.
