摘要
目前化学实验中产生的废液,不经处理便直接排入下水道的现象较为普遍,对水质和环境造成严重污染.首先将无机废液分成3类,一类含酸、碱废液;二类含有害重金属废液;三类含有害的阴离子废液.然后研究了这3类废液简单有效的处理方法,对废液和处理后的水质进行了分析.处理后的水质达到国家污水排放标准.
The waste liquid of chemical experiment is often directly discharged into sewers, This can causes serious pollution to the water and the environment. The inorganic waste liquid is classified into three kinds:acidic or basic waste liquid,harmful metal ionic waste liquid and anionic waste liquid. The simple and effective treatment is studied. The analysis of the waste liquid and treated water shows that the water quality reaches the stipulated discharge standard.
