污水自化粪池流出进入格栅,利用格栅拦截污水中的漂浮物和悬浮物,然后进入调节池,经过调节池调节水量均化水质,之后由污水提升泵将污水提入A级酸化池,污水在其内进行水解酸化,将难生物降解的大分子有机物分解为易于生物降解的小分子有机物。
Sewage flows out of septic tank and enters the grille. The grille is used to intercept the floating matter and suspended matter in the sewage, and then enters the regulating pool. After adjusting the water quantity and homogenizing the water quality in the regulating pool, the sewage is pumped into the A-level acidizing pool by the sewage lifting pump, in which the sewage is hydrolyzed and acidified, and the macromolecular organic matter which is difficult to biodegrade is decomposed into small molecular organic matter which is easy to biodegrade
同时,接受后续二沉池的的回流污泥,利用兼性微生物,在其内进行反硝化反应,将在O级氧化池中硝化反应产生的亚硝酸盐和硝酸盐还原为N2或N2O、NO。A级酸化池出水自流进入O级氧化池,由于污水经过前面的水解酸化,此时污水的可生化性大大提高,利用大量微生物来彻底去除污水中的有机物。
At the same time, the reflux sludge from the subsequent secondary clarifier was used for denitrification by facultative microorganisms, and nitrite and nitrate produced by nitrification in the O-grade oxidation www.yijingguan.cnwww.pingdifengtou.cnwww.xingtaibaojie.com.cn www.diandongmenn.com.cnwww.daishiganzaoj.cnwww.shidiaopenqua.cntank were reduced to N2 or N2O or NO. The effluent of A-level acidification tank flows into O-level oxidation tank. Because of the hydrolytic acidification of the sewage in front of it, the biodegradability of the sewage is greatly improved, and a large number of microorganisms are used to completely remove the organic matter in the sewage.
同时,利用好氧微生物在其内进行硝化反应,将污水中的氨氮(NH3-N)转化为亚硝酸盐(NO2-)和硝酸盐(NO3-),为A级酸化池的反硝化反应提供良好的条件。
At the same time, ammonia nitrogen (NH3-N) in sewage was converted into nitrite (NO2-) and nitrate (NO3-) by nitrification with aerobic microorganisms, which provided good conditions for denitrification in A-grade acidification tank.
