導流曝氣生物濾池在污水處理中的應用

   

7  結論

綜上所述，導流曝氣生物過濾技術在國內外20多年的應用和發展中日趨成熟，實踐證明在污水的二級或三級處理中采用是較為適宜的。問題是在該技術的應用中如何提高容積負荷（kgBOD₅／m³·d），降低水力停留時間（h），縮小反應器體積，減少占地面積，節省項目投資，降低運行費用，而又要保證出水達到標準要求。使該技術在污水處理中的應用更為合理并具有強勁的生命力。貴州長城環保科技有限公司新研制成功的“導流曝氣生物濾池”是一種高負荷、淹沒式、固定化生物膜三相導流反應器清污分流技術，其主要技術關鍵是提供一種導流曝氣生物過濾池，將生物氧化、生物過濾和沉降回流結合在一起，通過反沖洗雨生實現濾池的周期性運行，在污水的二級或三級處理中，充分地顯示出其處理負荷高、占地面積少、基建投資低、運行費用低等優越性，且出水水質達到或優于國家標準，實現中水回用。充分體現出其污水處理工程具有創新性、技術水平具有前瞻性、工程應用具有可靠性、地域應用具有代表性、實際操作具有穩定性、工程建設與運行具有經濟性，這對污水處理部門而言，無疑是一種尚佳的選擇。

Abstract: The conduction current biofilter is filters the principle according to the conduction current  biology, uses one kind of sewage treatment filter tank which the certain craft and the flow manufacture becomes, this filter tank technology has attained the national monopoly (the patent number: ZL200420033672.4). The filtertank structure is the   two conduction current type, for the biological contact, and filters the area for the biology. The filter tank technical key is the biological oxidation, the biology filters with the subsidence backflow unifies in together, through counter- flushing regeneration realization filter tank periodicity movement. In the sewage two levels of or in three level of processing practical applications, fully demonstrated its processing effect good, shoulders, the area high few, the initial cost low, the operating costare few and so on the merit, its water leakage water quality achievedor surpasses the national standard, in the realization the water sales commission.
