Abstract： |
The invention discloses a denitrify oxidizing lift waste biological reactor stuff field and filter liquid reflux technique, wherein the stuff field comprises a stabilize area, a stable methane area, a positive stuff area, while each area is connected with two filter liquid collecting pool, and each collecting pool is connected with one one-way valve connected with a filter liquid adjusting pool and connected to an on-site treatment sewage processing industry via valves. The invention utilizes the ability of biological reactor stuff field that absorbs nitrate and resists nitrated, and collects, pretreats and refluxes the filter liquid to obtain circular biological treatment conditions as aerobic, facultative, anaerobic, aerobic or the like. The invention can hold the COD density of outlet filter liquid under 1000mg/L, the NH3-N density under 15mg, and the total nitrogen remove rate higher than 90%. |
