A submerged membrane sequencing batch bioreactor was used to treat coke wastewater.Long running performance showed that due to the membrane interception,the nitrobacter is enriched in reactor in the interest of improving the nitrification rate;the maximum ammonia nitrogen loading can be 0.19 kg/(m3·d) with effluent ammonia nitrogen<1 mg/L (removal rate 99%).Long sludge retention time may result in the accumulation of metabolic products and high molecular materials,and thus inhibiting activity of nitrate bacteria and causing a ccumulation of NO2-,which is beneficial to the running of short-cut denitrif ication.However,too long retention time will affect the activity of nitrite bacteria,detrimental to the treatment effect of ammonia nitrogen.

采用浸没式膜生物反应器处理焦化废水的试验结果表明:膜的截留作用可使硝化菌在反应器内富集而有利于提高系统的硝化能力,其去除氨氮的最高负荷为0.19kg/(m3·d),出水氨氮<1mg/L(去除率为99%);泥龄长可能使微生物的代谢产物或其他大分子物质积累,从而抑制硝酸盐细菌的活性,导致NO2-积累而有利于短程脱氮的进行,但泥龄过长也会影响亚硝酸盐细菌的活性,从而影响对氨氮的处理效果。

Under anaerobic conditions nitrates and nitrites are both reduced by a process called denitrification.

在厌氧条件下,硝酸盐和亚硝酸盐通过脱硝作用被还原。

The results show that, the nitrate-N concentration in groundwater in the reed area was 0.2~0.8mg/L and significantly lower than that in surrounding wells (more than 20mg/L), and the reed wetland can remove nitrate pollution in shallow groundwater. The distribution of denitrifying bacteria showed obvious rhizosphere effect, and the higher biodenitrification in natural reed wetland was related to the distribution of denitrifying bacteria. There was a negative relationship between the nitrate-N concentration and the number of denitrifying bacteria in groundwater.

结果表明:芦苇区浅层地下水中硝酸盐氮仅为0.2~0.8mg/L,远低于湿地周围井水中硝酸盐氮质量浓度(大于20mg/L),芦苇湿地能够去除浅层地下水中硝酸盐污染;反硝化细菌在土壤中的分布呈现明显的根际效应;野生芦苇湿地较强的生物脱氮作用与反硝化细菌分布有关,地下水中硝酸盐氮含量与反硝化细菌分布呈负相关。

alkalinity:硷度

●增加硷度(Alkalinity)与稳定pH值. ●活沙过滤系统比较其他过滤系统之最大优点,是藉由活沙中的脱氮作用(dinitrification)除去水中的硝酸盐. ●配合蛋白质过滤器(protein skimmer)的使用,溶解於水中的有机物质也相对的减少.

Denitrification:脱硝作用

可以透过微生物的脱硝作用(denitrification)来移除废水中的硝酸盐(Nitrate),通常会加入小量的甲醇来防止细菌以废水当作碳的来源而滋生. 臭氧废水处理(Ozone
