摘要:隨著國(guó)家污水排放標(biāo)準(zhǔn)的提升,污水處理廠生化池需要投加碳源來提高總氮去除率,做好生物反硝化,實(shí)現(xiàn)出水達(dá)標(biāo)排放。研究生化系統(tǒng)使用單一碳源或者復(fù)合碳源進(jìn)行生物反硝化時(shí)總氮和硝態(tài)氮去除效率,可以為污水處理廠選擇碳源提供參考,提高生化系統(tǒng)總氮去除率,降低污水處理廠運(yùn)行成本。

Abstract: With the improvement of national sewage discharge standards, carbon sources need to be added to the biochemical tanks of sewage treatment plants to increase the total nitrogen removal rate, carry out biological denitrification, and achieve effluent discharge standards. Studying the removal efficiency of total nitrogen and nitrate nitrogen in biological denitrification using a single or composite carbon source in biochemical systems can provide reference for selecting carbon sources for sewage treatment plants, improve the total nitrogen removal rate of biochemical systems, and reduce the operating costs of sewage treatment plants.
Keywords: single carbon source; composite carbon source; biological denitrification; denitrification efficiency
污水處理廠反硝化碳源不足時(shí),一般采用投加碳源的方式來確保出水總氮排放達(dá)標(biāo)。(剩余3875字)
