生物促生剂、解毒剂在接触氧化池中的应用

Application of bio-energizer and micatrol in contact oxidation pond

为增强生物接触氧化池抗污染物冲击能力和改善出水水质,在生物接触氧化池中投加生物促生剂、生物解毒剂。经过20多天的试验,结果表明:正常运行的情况下,投加生物药剂的生物接触氧化池,对CODCr的去除率提高20%以上;在受硫化物冲击后,投加生物药剂不但可以改善出水水质,而且能缩短系统恢复时间48 h。生物促生剂、生物解毒剂能增强生物膜的活性和生物多样性、提高系统抗冲击能力和改善系统出水水质。

In order to enhance the anti-fouling effluent water quality, bio-energizer and micatrol was capability of bio-contact oxidation pond and improve the added into the pond. The results of a 20-day test showed that： under normal operating condition, the removal rate of CODcr in the bio-contact oxidation pond added with bio-energizer was increased by more than 20%; During the treatment of sulfide polluted wastewater, dosing bio- energizer could not only improve the effluent water quality but also shorten the recovery time of the system for 48 h. It could be seen that, bio-energizer and micatrol could heighten the activity and biodiversity of the biofilm, en- hance the anti-impact ability of the system and imnrove the effluent water quality as well.
