    摘要:

    本文对三种供试工业废弃物,经土地处理后表明,发光细菌毒性明显降低,有的废渣处理物毒性已消除;Ames试验和发光细菌自发暗变种的遗传毒性减弱,由阳性下降为阴性,或阳性程度明显减弱。急性毒性和遗传毒性下降的根本原因在于土地处理物中有毒有机化学物阵解所至。木试验废渣经土地处理后,其可萃取有机物含量明显下降,总下降率为40-71%,主要的有机化学物降解率为50-90%.从而表明,土地处理是工业废渣很有前途的处理途径。

    Abstract:

    The acute toxicity from three types of industrial wastes in photobacteria test significantly decreased, even disappeared, after land treatment. The genetic toxicity of samples both in the Ames test and in the spontaneous dark variant of photobacteria test was weakened from positive to negative, or the degree of positive was obviously weakened. The basic reason why both the acute toxicity and the genetic toxicity were lowered could be attributed to the degradation of the toxic organic chemicals in land treatment substances. The contents of extractable organic chemicats from three types of industrial wastes fell clearly after land treatment. The total degradation rate of organic substances was 40-70%.The degradation rate of primary organic chemicals was 50-90%.It was indicated that land treatment of industrial wastes could get a satisfactory effect, and land treatment would be a prospective good way to the industrial wastes treatment.
