Abstract

The present invention discloses an integral multistage simultaneous nitrification and denitrification biological membrane system denitrification method and device, and belongs to the technical field of biological treatment of sewage, and the device is integrally constructed sequentially by a regulatory region, a multistage simultaneous nitrification and denitrification region, a flow diversion region and a precipitation region. The multistage simultaneous nitrification and denitrification region is in a multiple-groove pushing flow form, each reaction groove is provided with an aeration system and a multi-section water inlet device; the precipitation region is provided with an overflow port and an inclined plate sedimentation tank; a multi-section water inlet pipe connects each reaction groove of the regulatory region and the multistage simultaneous nitrification and denitrification region, by full use of the advantages of the simultaneous nitrification and denitrification and control of the operation conditions, the nitrification and denitrification are integrated in a reaction zone without adding of additional alkalinity and need of stirring, nitrification liquid reflux and sludge return systems, energy is saved, and cost is reduced, load of shock resistance of the system is enhanced by the multistage pushing flow structure, by multi-section water inlet design, the role of system denitrification is enhanced, the denitrification and carbon removal effects are stable, and maintenance and management are convenient.

Description

technical field [0001] The invention belongs to the technical field of sewage biological treatment, in particular to an integrated multi-stage simultaneous nitrification and denitrification biofilm system denitrification method and device. Background technique [0002] my country has a large rural population and a large amount of domestic sewage discharge, most of which are directly discharged into water bodies without effective treatment, resulting in serious water environmental pollution problems. Rural villages and market towns are scattered, and it is difficult to centrally transport sewage to sewage treatment plants for treatment; however, sewage treatment systems such as land treatment technology and bio-ecological combination technology that have received widespread attention in China currently occupy a large area and are affected by seasons, regions and other environments. The impact is large, and the treatment effect is unstable. Therefore, the sewage treatment tec...
