Environment-friendly wastewater denitrification treatment device and use method thereof

Abstract

The invention discloses an environment-friendly wastewater denitrification treatment device, which comprises a denitrification reaction pipe, an aeration pipe and a microwave reaction box, wherein a stirring motor is arranged above the denitrification reaction pipe; a stirring paddle is coaxially arranged inside the stirring motor; the stirring paddle penetrates through the denitrification reaction pipe; reaction gas recovery openings are symmetrically formed in the two sides of the stirring motor; the denitrification reaction pipe is internally filled with reaction filling materials; an L-shaped aeration pipe penetrates through one side of the denitrification reaction pipe; a water inlet is formed in the other side of the denitrification reaction pipe; a water outlet is formed under the denitrification reaction pipe; the denitrification reaction pipe penetrates through the microwave reaction box; a plurality of microwave generators are arranged inside the microwave reaction box; a microwave energy output device is arranged above the microwave generators; a magnet is connected under the microwave energy output device. The environment-friendly wastewater denitrification treatment device has the advantages that the investment is low; the operation cost is low; the occupied area of the equipment is small; the treatment efficiency is high; the management is convenient, and the like. The equipment has good market application and industrial prospects.

Description

technical field [0001] The invention relates to a waste water denitrification technology, in particular to an environment-friendly waste water denitrification treatment device and a use method thereof. Background technique [0002] Nitrogen pollution will cause eutrophication of water bodies, and with the rapid development of urbanization and industrialization in my country, this problem has become increasingly serious and has caused many public environmental safety incidents. For this reason, in recent years, the state has successively promulgated and implemented new sewage discharge standards, among which the discharge requirements for ammonia nitrogen have been particularly improved, and the total nitrogen in the effluent has been limited for the first time. Physical and chemical denitrification technologies mainly include breakpoint chlorination, chemical precipitation, adsorption, ion exchange, stripping and gas stripping, liquid membrane, electrodialysis, catalytic wet...

AI Technical Summary

Problems solved by technology

[0005] Preferably, the reaction filler includes nitrification sludge, anammox sludge and hydroxylamine, and hydroxylamine is put into the denitrification reaction tube at a frequency of 3 to 5 days / time, which overcomes the long-term problems existing in the current integrated denitrification reactor. Under operation, nitrifying bacteria gradually take advantage of the competition with anammox bacteria, resulting in nitrate accumulation, poor impact resistance, poor stability, and weak recovery ability. Its denitrification load is high and long-term operation stability is strong. Strong recovery ability after being strongly inhibited, enabling cost-effective removal of total nitrogen
