茂名是我国新建的一座石油城,以石油工业为主要工业,近年来有很大发展,其废水主要是干馏废水和原油废水,1958年开始使用石油废水灌溉农田,粮食等作物普遍增产,1962年扩大废水灌溉面积。但废水成份复杂,国内外经口毒性文献资料未见报导。因此使用石油废水灌溉农田,其粮食毒性如何,即成为急待解决的问题。本次实验以油母页岩干馏废水灌溉大米喂饲大白鼠,观察其毒性影响,以为我国人造石油废水灌溉粮能否使用问题作出初步评价。
Maoming is an oil city newly built in our country. The oil industry is the major industry. In recent years, its development has been greatly developed. Its waste water is primarily distilled water and crude oil wastewater. In 1958, it began to use oil waste water to irrigate farmlands. Grain production generally increased. In 1962 Expand waste irrigation area. However, the composition of wastewater is complex, and no literature on oral toxicity has been reported at home and abroad. Therefore, the use of oil wastewater irrigation of farmland, its food toxicity, which has become an urgent issue. In this experiment, rats were fed with rice oil shale distilling waste water to observe its toxicity, and to make a preliminary assessment of the use of artificial petroleum waste water irrigated grain in China.
