Description
Technical field
The invention belongs to water treatment field, particularly a kind of gac composite water disposal agent also relates to the preparation method of this water conditioner and the application of this water conditioner in the control body eutrophication.
Background technology
Body eutrophication refers to the nutritional substances such as the excessive nitrogen of water body admittance, phosphorus, Measures of Algae in Water Body and other hydrobionts are bred extremely, water transparency and dissolved oxygen change, and cause water body to worsen, thereby make water ecological setting and water function be hindered and destroy.The body eutrophication problem has become the water pollution control difficult problem of world today's property, is also one of global environmental problem.From world wide, 30%～40% lake and reservoir have suffered the impact of eutrophication in various degree in the world.And the eutrophication problem that China's water pollution causes is very outstanding, is one of main Environmental Problems of puzzlement Chinese Economy Development.
The control of body eutrophication is mainly by two kinds of means: the one, control the exogenous nutrition material inputs, and if reduce or block the nutritive substance of outside input, just make water body lose the possibility of nutritive substance enrichment; The 2nd, reduce the endogenous Nutrient loads, effectively controlling inside, lake is the enrichment of Sediments phosphorus.Research finds, in Dianchi Lake, Yunnan Province, 80% nitrogen and 90% phosphorus all are distributed in bed mud; Hangzhou West Lake endogenous pollution load has reached 41% of extraneous contamination load; Chaohu, Anhui Province, China endogenous pollution load is 21% of extraneous load.If polluted bed mud is not added any control, even external source is controlled fully, endogenous release still can make the overlying water Pollutant levels of surface water body be in higher level.In order to prevent and treat the eutrophication of water body, people have carried out a large amount of work, and have sought out a lot of effective methods.But these methods can only be controlled separately endogenous mostly or external source is polluted, and need to adopt simultaneously multiple diverse ways, cause that cost is higher, complicated operation, may cause secondary pollution simultaneously.Therefore, we seek a kind of release that both can control the water body internal contamination at expectation, can reduce again the method for the concentration of the nutritive substance such as overlying water nitrogen phosphorus and other pollution substances.
Summary of the invention
