| 摘 要： | 河流水体受污染后，在自然环境因素的影响下由各种物理、化学及生物作用能得到一定的净化。哈尔滨市松花江段河流水质净化作用主要包括稀释、吸附、江底沉积物的机械过滤与吸附和絮凝沉淀作用。哈尔滨市松花江断面正处于河流侵蚀与堆积交替动态平衡中，可不断提供新的活性表面，使河底沉积物的净化作用持久不衰。该特殊的地质条件是本段河流保持较强净化作用的关键，妥善利用水环境净化能力是一种经济有效的水污染控制手段。

| Abstract: | When river water body is polluted, it can be purified by kinds of physical, chemical and biologic functions under natural environment factors. The river water quality functions of the Songhua River in Haerbin include dilution, adsorption, mechanical filtration, adsorption and condensation of deposit substance on the bed of river. The function of the deposit substance on the bed of river is invariable because the section of Songhua River can supply new active surface when it is in alternatively dynamic balance of river erosion and accumulation. The special geological conditions are key to purification function of this section. It is a kind of economical and effective means of controlling water-body pollution to avail of water environment purification capacity properly. |
