流域水体生态修复技术探讨

针对河道等自然流域的水体污染物进行生态治理，作者提出运用三个独立步骤而形成一道自然水体修复功能：第一步，优选良性微生物株群并持续发展与供给；第二步，运用河道功能增加水中的溶解氧；第三步，建立流域水体生物链，从而达到流域水体消纳污染物的自净效果。

Probe into Water Body Eco-remediation Technology in River Basin

Aimed at the water body pollutants in natural river basin of the river-course, eco-treatment is carried out. The author puts forward three independent steps to form a remediation function of natural water body： first step： select the fine micro- population, sustainable development and supply; the secondary step： exercise river-course function to increase dissolved oxygen in water; the third step： set up biological chain of water body in river basin so as to obtain the self-clean result that eliminates the pollutants in water body of river basin.
