Problems solved by technology

Secondary biological treatment projects have been launched one after another, effectively controlling organic pollution, but the ammonia nitrogen in the effluent is high, which is still a serious source of environmental pollution
[0004] The existing nitrification reactor is mainly evolved from the activated sludge tank. During the oxygenation process of the aeration tank, the residence time of the bubbles in the liquid phase is relatively short, and the volumetric oxygen supply efficiency and oxygen utilization rate need to be improved; The air tank and the secondary sedimentation tank are set separately, and the sludge backflow consumes power and destroys the sludge floc structure, which is not conducive to the separation of sludge and water

Abstract

The present invention discloses one kind of efficient double unit biological nitration reactor comprising one external unit and one inner unit. The external unit as the reactor body is provided with an upward reaction chamber, an aerating pipe, an aerating head, a cyclonic water distributor, a sludge pipe, a slag pipe and a sampling port; and the inner unit is one sludge deposition system including a settling chamber, a circulating pipe, a guide tube and a gas baffle. The settling chamber is divided with baffles into a slow flow area, an upward flow area, a downward flow area and an overflow area. The present invention has the advantages of homogeneous water distribution to ensure high reaction efficiency, separation between the reaction chamber and settling chamber to eliminate the influence of the flow state in the reaction chamber on the operation in the settling chamber, reinforced matrix transfer and high volume conversion efficiency.

Description

technical field [0001] The invention relates to a high-efficiency binary biological nitrification 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 projects have been launched one after another, effectively controlling organic pollution, but the ammonia nitrogen in the effluent is high, which 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. [0003] The methods of denitrifi...
