Abstract

The invention provides an AO combined enhanced nitrogen and carbon removal device with a built-in MBR. The AO combined enhanced nitrogen and carbon removal device comprises a box body, a pretreatmentunit arranged in the box body and used for carrying out earlier-stage treatment on wastewater, and a deep treatment unit arranged in the box body and used for carrying out retreatment on the wastewater treated by the pretreatment unit, wherein the deep treatment unit comprises an AO treatment unit and an MBR treatment unit. According to the invention, the AO combined enhanced nitrogen and carbon removal device is reasonable in overall structural design, the MBR membrane assembly is selectively placed in the AO process for use through the lifting unit, the sludge reflux quantity and the sludgeconcentration in the AO process can be effectively increased, and the SS concentration of effluent can be reduced, so that the denitrification and decarbonization effects can be effectively enhanced;and the AO combined enhanced nitrogen and carbon removal device has the advantages of high efficiency, small occupied area, low investment cost and the like, and has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment equipment, in particular to an AO combination enhanced nitrogen and carbon removal device with a built-in MBR. Background technique [0002] In recent years, with the rapid development of my country's national economy and the improvement of people's living standards, the problem of water pollution has become increasingly severe. Among them, organic matter and nitrogen-containing pollutants are more prominent. These pollutants are not discharged up to the standard, leading to eutrophication of water bodies in large areas, causing serious water ecological disasters and secondary disasters, and bringing huge environmental pollution to the country. and economic loss. To this end, the country has successively issued more stringent laws and regulations to limit the discharge of such wastewater. Therefore, the development of efficient organic matter removal and denitrification treatment pr...
