    The experiments showed that four pigments in different solutions of both waste water diluted are lower than those of the control.
    试验表明在不同稀释倍数的两种污水中,四种色素都低于对照。
    Chlorophyll a and b, and β-carotene contents in the waste water of Kunming Smeltery are much lower than those in the waste water of Hongwei Paper Mill, but the response of xanthophyll on both waste water is contrary.
    昆明冶炼厂废水比红卫造纸厂洗浆污水使叶绿素a和b,以及β-胡萝卜素含量降低更多,叶黄素对两种污水的反应却相反。
    The silklike green algae Cladophora sp., a dominant species in Hangu Sewage Lagoon, is able in our experiment to accumulate and remove mercury from brackish waste water, and can still grow well even under 1.0mg/L of mercury in water. But poisoning symptom appears when the concentrations are higher than 2.0 mg/L for 48 h.
    于1982年以刚毛藻为材料测定了其在汉沽污水库中对汞的累积量,现场测定和室内试验结果表明:(1)刚毛藻(Cladophora)对汞毒性的耐受力较强,在1.0mg/L以下汞培养液中经48h生长正常;
    The results show that the variation of microbial biomass in waste water has no relation to the concentrations of Cd or Pb.
    结果表明,污水中微生物量的变化与Cd、Pb浓度不相关。
    The dominant microorganisms in Cd and Pb waste water are Erwuba, Alacligenes, Arthrobacter, Candida, Aspergillus and Cladosporinm.
    含Cd、Pb污水中的优势菌有欧文氏菌、产碱杆菌、节细菌、假丝酵母、曲霉和枝孢霉。
    The results show that SRB propagates rapidly at pH=7 ̄9, and can not keep alive at pH=11. In the waste water of oil field, SRB has a little effect on anodic processes,but promotes markedly the cathodic depolarization and then accelerates the corrosion of steel.
    结果表明,SRB在pH=7~9时大量繁殖生长,在pH=11时不能存活。 在油田污水中,SRB对腐蚀的阳极过程影响不大,对阴极却有显著的去极化作用而加快了钢铁腐蚀。
