By means of the analysis of pollution status of Yongnian County sewage treatment plant and general situation of the whole plant, the problems about pollution are summarized in this paper, and we make a number of programs about cleaner production in non / low-cost and medium / high fee proposals. Through the study of the program we reach the cleaner production as a way of environmental protection can...
Arsenic compounds are highly toxic and the toxicity of trivalent arsenic compounds is more powerful than others. There are many ways of its determination. This article describes the determination of trace Arsenic in Qin River by Paper Absorption Spectrophotometry. The result indicate that the limit of detection of this method is 0.001 mg/L, the standard deviation is 0.0007 mg/L and the mark-on recovery...

Taking these problems into consideration, the author puts forward some feasible strategies and suggestions which can direct the development of eco-environment in a right way...
Fuzzy mathematics method is used to establish the corresponding membership function in order to analyze the water quality during specific years and forecast its trend. The result shows that using fuzzy comprehensive evaluation can scientifically evaluate the water quality of Zhanghe River, obtaining the V, V, III, II levels for different years and producing the prevention measures.
In order to set up a water quality assessment system for Zhanghe river fittingly, a fuzzy comprehensive evaluation model based on fuzzy theory is studied. The application of this method to evaluate the water quality in Xida section is given as an example for demonstration. According to the environmental quality standard of surface water, the membership function is established. So as to ensure the...
