Abstract

The invention discloses an aerobic-anoxic-anaerobic integrated module type fast denitrogenation reactor for sewage and a treatment method thereof and relates to an integrated sewage treatment device, which is particularly suitable for fast integrated treatment for sewage by denitrogenation technology. The device is designed for solving the problems of complex process, high treatment expense, additional carbon source and regulation of outflow pH, difficult zero discharge and the like existing in aerobic-anoxic-anaerobic denitrogenation sewage treatment. Aerobic-anoxic-anaerobic processes are technically integrated to enable sewage to be always in an alternate aerobic-anoxic-anaerobic environment; an organic carbon source, organic nitrogen and total phosphorus are distributed reasonably to avoid shortage of carbon source during denitrogenation, so that total nitrogen and total phosphorus are converted effectively, the effect of denitrogenation and dephosphorization are improved, and discharged water reaches first discharge standard of Integrated Wstewater Discharge Standard (GB8978-1996). The device is used for treating municipal domestic sewage, especially sewage of middle and small stations along railway lines.

Description

technical field [0001] The invention relates to an integrated sewage treatment device, which is especially suitable for the integrated treatment of sewage with fast denitrification technology. Background technique [0002] In the field of sewage treatment, there are not many high-efficiency and fast denitrification treatment equipment suitable for small and medium-sized sewage treatment stations. For example, the reuse of sewage from office buildings, the recycling of sewage from living quarters, automobiles, and train stations, and the discharge of wastewater from food factories, meat joint factories, brewing wastewater, starch wastewater, etc., all of which require efficient treatment equipment to achieve their goals. Discharge. [0003] In recent years, some small sewage treatment equipment have emerged, including membrane-bioreactor, biological aerated filter, upflow sludge anaerobic bed, etc. Although the treatment efficiency is high, the equipment management is compli...
