In this paper, the phospho-tungstic acid colorimetric method has been adopted to determine the micro hydroquinone and metol in the wastewater of black-white developer. It was tested to eliminate the inference of sodium sulfite by means of heating break-up of analyses and mercury chloride masking. The conditions were set and the accuracy was examined. This method is adoptable to control the quality of the waste water in the black-white developer drained after being purified with active carbon.

This paper reports acute toxicity of effluents in the process of exploiting the vanadium trtanornagnetite to carps, Cyprinus caprio and avoidance capacity of this species to these effluents. Characteristics of the three whole effluents and it’s biological assessment have been discussed. Bioassays using this freshwater fish as the test organisms in the laboratory show that the 24-hour LC_(50) value is 33.2% and 96-hour LC_(50) value is 26.6% for the cleared effluent of ore dressing plant Lit 23.5±0.5℃ of the water tested. However, both the cleared effluents of plants of smelting and coal cleaning do not cause acute lethal to this species during 168-hour. The data of avoidance test in the laboratory indicate that carps have avoided at least two concentrations of the three cleared effluents withm the concentrations tested, although the avoidance differs with different effluents. This species have avoided 100% and 100% oredressing effluent; 2.0%, 10% and 100% for smelting effluent; 10% and 100% for coal cleaning effluent, respectively. At different testing stations along the river, in the lower reaichs of the outlet for effluents, are laid up the“live box”to determine to toxicity of effluents. The results have been obtained from observations of the field bioassays.Accord ing to the LT_(50) and LT_(100) for this species, the toxicity of the three efluents is greater than that in the laboratory test. The various results obtained from present studies in the laboratory and field are closely related to the chemical characteristics of whole effluents. It is evident that poisonous effects of abnomally high concentrations of suspended matters and metals in effluents for aquatic organisms should be considered.

本文报导釠钛磁铁共生矿的开发过程中三种废水对鲤鱼的急性毒性,以及鲤鱼对这些废水的回避能力。试验水温为23.5±0.5℃,澄清的尾矿废水的96小时LC_(50)为26.6%;澄清的冶炼废水和洗煤废水在168小时内均不引起鲤鱼急性致死。鲤鱼的回避能力随澄清的废水种类不同而异,能分别回避10%和100%尾矿废水;2.0%、10%和100%冶炼废水;10%和100%洗煤废水,回避能力与废水浓度成正相关。在废水排出口下游的现场生物检测所得LT_(50)和LT_(100)值表明,这三种废水的毒性比实验室试验的毒性大得多。对三种全废水的水质特征进行了化学分析,并就其水质特征讨论这些废水的生物学评价。
