新型微生物菌剂在生活污水处理中的应用研究

Study on application of a new type of microbial agent in domestic sewage treatment

对利用新的微生物源抗菌除臭剂去除生活污水中的COD、NH4＋-N、TP及臭气的效果进行了评价。结果表明：（1）在好氧的条件下，当V菌液／V污水的比值为5／10000～1／1000时，COD的去除率提高幅度较大，为10％左右；当V菌液／V污水的比值为5／1000时，对污水中NH4＋-N的去除效果最好，增幅达37．62％；只有V菌液／V污水达到5／1000以上时，对除磷才有较显著的促进作用，增幅约7％。（2）对污水除臭有很好的效果，不同嗅阈值的污水应选择适宜浓度的菌液。

The effect of a new type of microbial antibacterial deodorant was evaluated through its processing of domestic sewage, COD, NH4＋-N, TP and odor. Results show that under the condition of aerobic, when the volume ratio of the deodorant and polluted water is 5/10 000 to 1/1 000, it can significantly increase the removal rate of COD to 10% ; the promotion effects of NH4＋ -N removal would be best when the ratio is 5/1 000 with an increase of 37.62%. And the promotion effects of P removal could be remarkable, approximately amplitude 7% when the ratio is beyond 5/1 000. It has a very good effect on odor-masking, and different polluted waters should be treated with a suitable concentration of it.
