Arc reactor

Abstract

The invention discloses an arc reactor. A reactor main body comprises a water distribution region, a main reaction region, an auxiliary reaction region, a three-phase separation region and a precipitation region from bottom to top. The main reaction region is divided into a first reaction chamber and a second reaction chamber by a three-tube separator; the two reaction chambers control automatic gas stirring through respective gas-stirring control tubes; and the auxiliary reaction region is located above the main reaction region for further degrading the matrix carried by the gas on the main reaction region. The invention has the advantages as follows: (1) sewage can be effectively intercepted and the microbe in the reactor is maintained through the three-tube separator and the precipitation region; (2) the main reaction region is connected with the auxiliary reaction region in series to prevent the matrix from backmixing and improve the processing efficiency; (3) the mass transferring effect can be strengthened and the dead spaces of the reactor are reduced through respective gas stirring in two reaction chambers in the main reaction region; and (4) the matrix carried by short stream in the main reaction region can be complementally processed and the negative effect caused by the short stream is prevented by matching the heights of the main reaction region and the auxiliary reaction region.

Description

technical field [0001] The invention relates to a reactor, in particular to an Anqi reactor. Background technique [0002] After the implementation of "One Control and Two Standards" in 2000, my country's organic pollution has been effectively curbed, and nitrogen and phosphorus pollution has become a major environmental problem (according to the Bulletin on the State of the Environment in China, ammonia nitrogen emissions in 2009 reached 1.226 million tons). The frequent occurrence of "water blooms" in lakes and "red tides" in coastal waters caused by nitrogen and phosphorus pollution has endangered many industries such as agriculture, fishery, tourism, and poses a serious threat to drinking water sanitation and food safety. The prevention and control of nitrogen pollution is imminent and urgent. [0003] Conventional denitrification technologies are incompatible with the development direction of a sustainable and low-carbon economy due to their low efficiency and high cos...

AI Technical Summary

Problems solved by technology

This type of anaerobic ammonium oxidation reactor has the following problems: ①sludge loss is serious, and the retention capacity of bacteria is not good; ②material backmixing is serious, and the reaction efficiency is limited; ③the dead zone area is large, and channel flow and short flow occur frequently ; ④ Use pumps to return sludge, which not only increases equipment costs and power consumption, but also destroys the sludge structure; ⑤ Sludge frequently exchanges up and down in the reactor, withstands large static pressure changes, and biological cells are easy to rupture
