摘要
本文介绍了大庆30万吨乙烯工程的化工废水处理装置和腈纶废水处理装置中曝气池的不同微型动物生态特点.提出进水水质和环境因素决定了微型动物的固有种属;水质波动是引起微型动物种属和数量变化的主要原因;微型动物的种类和数量变化预示着曝气池进、出水水质发生了变化.
The ecological features of various microzoons in the aeration tanks of wastewater treatment plants to treat the chemical and acrylic fibers production wastewa-ters in Daqing ethylene facility of 300 thousand tons capacity per year in Heilongjiang province are described in this paper. The authors consider that the essential species of the microzoon are decided by the characters of influent and environmental factors, the variations on species and numbers of microzoon are caused mainly by fluctuation of wastewater quality and the variations on species and numbers of microzoon shall anticipate the quality changes of influent and effluent of aeration tank.
