Problems solved by technology

Secondary biological treatment has been launched one after another. Although it has played a good role in curbing organic pollution, the high nitrogen content in the effluent is still a serious source of environmental pollution.
Separating the activated sludge with the secondary settling tank and sending it back to the anaerobic reactor through the reflux pump not only increases the equipment and consumes power, but also destroys the structure of the activated sludge, which is not conducive to the formation of granular sludge with excellent sedimentation performance and the separation of sludge and water

Abstract

The present invention discloses one kind of efficient anaerobic ammoxidation reactor comprising a reactor body and support legs. The reactor body has a sludge settling chamber with triphase separator, overflow weir, liquid sealing groove, liquid seal water level controller and liquid seal groove slag exhaust pipe; a flaring chamber with conic baffle; an upward flow reactor with stuffng; a cyclonic water distributor; said a four-way pipe comprising a water inlet pipe, a sludge exhaust pipe and an outer circulating pipe. The present invention has capacity of efficiently remaining anaerobic ammoxidation bacteria, great anaerobic ammoxidation capacity, high impact resistance and other advantages.

Description

technical field [0001] The invention relates to a high-efficiency anaerobic ammonia oxidation reactor. Background technique [0002] With the development of industrial and agricultural production and the improvement of people's living standards, the discharge of nitrogenous organic matter has increased dramatically. Secondary biological treatment has been launched one after another. Although it has played a good role in curbing organic pollution, the high nitrogen content in the effluent is still a serious source of environmental pollution. Nitrogen pollution is extremely harmful. Ammonia entering the water body can not only induce "eutrophication" and cause the disorder of the aquatic ecosystem, but also consume dissolved oxygen, resulting in hypoxia in the water body, affecting the oxygen transfer of strontium in fish, making fish Lethal; react with chlorine gas to form chloramine, which affects chlorination disinfection treatment. Therefore, it is imperative to control ...
