柴河水库流域主要重金属平衡估算及水环境容量研究

本文根据物质守恒原理，对柴河铅锌矿进行了物料平衡估算并确定了柴河流域主要重金属的平衡关系．同时．利用柴河水库水文资料和当地天然河流重金属背景值，推算出柴河水库几种重金属的最大环境容量．为今后铁岭地区经济发展与水资源保护提供依据．

STUDY ON HEAVY METAL BALANCE APPRAISE AND WATERENVIRONMENT CAPACITY IN CHAIHE RESERVOIR

Chaihe Reservoir is an important water resources for Tieling city in LiaoningProvince. To protect the water resources,Tieling governmant decided to build a nature protectionzone in Chaihe basin.Chaihe Lead -Zinc Mine was the main pollution source of heavy metals inChaihe basin.We studied the heavy metals pollution in Chihe reservoir basin and calculated thedistrubute of heavy metals from Chaihe Lead -Zinc Mine in the basin.The study indicats thatthere was about 256 tons heavy metals input to the Chaihe basin from the Chaihe Lead-ZincMine with its waste water since the mine built in 1996,most of them remains in the reservoirssediment(about 148 tons),and about 2 tons in river sediment,ahout 6 tons in soil,about 19 tonswashout wint the water.Finally,we compute the environmental capcity for heavy metals of Chaihe revervior by the data of Chaihe and its nature background of heavy metals.
