张掖地区造纸厂废水灌溉区域微型生物调查研究

A study of microbiota in irrigated area aroud Zhangye paper mill

通过对造纸废水流经灌区不同点进行微型生物监测 ,从微型生物的指示性角度出发 ,来说明造纸废水水质污染状况。通过监测得知 ,废水灌区微型生物共有 3 8种。其中藻类 1 0种 ,原生动物 2 8种。 3 8种微型生物均属多污性、α-中污性或 β-中污性种类 ,说明造纸废水治理效果较差且对灌区农作物及生态污染较严重。如何解决废水污染及灌区对废水的依赖性 ,应引起有关部门的重视。

This paper attempts to analyze and demonstrate the poplluted water quality of pulp and paper wastewater from the indicatin of the microbiota by observing and monitoring the microbiota in the irrigated area around Zhangye Paper MillThe results show that there are 38 types of microbiota in the area (algae ,10;protozoa,18)Most of 38 microbiota are polysaprobic zone,α-mesosaprobic zone or β-oligosaprobic zone This shows that wastewater treatment here is not effective and pollution to the crops and biology of the area is still a big problem So great attention must be paid to how to get rid of the wastewater pollution and the dependence on the wastewater of this area
