The experiment is began with the runoff quality on the diverse roofage and different grade roadway, the results are as follows:(1) The concentration of contamination is different with the diverse roofage, and SS value is also different with the style roof;(2) In the beginning , the concentration of COD value and SS value is higher ,but the runoff quality will be reduced to steady gradually along with the rainfall duration increase;(3) The city roadway runoff is worse than the roadway of university ,because the city roadway runoff involve vehicle n people and the sanitation and material of roadway;(4) Based on the analysis of rainwater quality , the paper provide the process of rainwater treatment for roof, roadway, and lawn.

对教学区内不同建筑物，及道路上的雨水径流水质进行监测，得出以下结论：(1)材料不同，径流雨水中污染物浓度不同，屋顶类型不同，径流雨水中SS浓度亦不同；(2)初期径流污染物浓度很高，随降雨历时的延长，COD和SS浓度逐渐下降并趋于稳定；(3)道路污染与路面材料、来往车辆、人员流动、路面卫生状况有关。市区道路相比校园内道路，水质较差；(4)对雨水水质分析基础上，分别对建筑屋顶、道路、绿地提出雨水利用的处理工艺。

The invention relates to a method for treating gaseous VOCs by a solid extraction-electro-catalytic oxidation method and a device thereof. The method has the steps that: firstly, an electromagnetic type air compressor is used for controlling the gas flowing velocity by a glass rotameter so as to ensure contaminations in the contamination solution in a gas washing bottle to be stripped into an electrochemical reactor; secondly, microporous aeration heads are distributed in the electrochemical reactor, after being stripped into the electrochemical reactor, the gas is distributed in the electrochemical reactor by the microporous aeration heads, takes parts in the electrochemical reaction and passes through the cathode of absorptive and conductive porous material and the anode of iron sheet in sequence; thirdly, the treated gas finally flows out from the top end of the electrochemical reactor and enters into the gas absorption solution.

本发明涉及一种固态萃取-电催化氧化法处理气态VOCs的方法及装置，方法步骤：第一步，电磁式空压机通过玻璃转子流量计控制气体流速，将气体洗瓶中的污染物溶液中的污染物吹脱进电化学反应器；第二步：电化学反应器中布有微孔曝气头，气体吹脱进入电化学反应器后，通过微孔曝气头分布于电化学反应器内，参加电化学反应，依次经过通过吸附性导电多孔材料阴极和Fe片阳极；第三步，经处理后的气体最后从电化学反应器顶端流出进入气体吸收溶液。

Therefore it's necessary to contol the concentration of TW80 to use it in the remediation of pyrene contaminated soil by AMF and corn integrated systerm.4. The AMF community and the single species derived from rock oil-contaminated soil all can be combined with corn and promote the remidation of pyrene contaminated soil , the original AMF community has obvious advantages and behave best.The residual pyrene concentration of soil in the treatments with the mixed AMF community M4 (Glomus intraradices, Glomus mosseae, Glomus etunicatum and Acaulospora tuberculata) and corn integrated systerm got 0.12mg/kg,0.54mg/kg and 3.92mg/kg respectively in 1mg/kg, 10mg/kg and 50 mg/kg pyrene treatments,decreased 32.6%,58.6% and 42.2% respectively than that of the treatment of M1,decreased 28.1%,59.9% and 36.6% than that of M2(G.intradices), decreased 2.7%,55% and 23.5% than that of M3 (G.intradices + G.mossea).5.Large scale reproduce overall of AMF community which coming from rud oil-contaminated soil in the absence of the original conditions will change the quantiy,composition and structure of the AMF population and may has negative impact on it's function in the remedition of soil pyrene contamination.

因此，在植物与AMF联合修复土壤芘污染中使用TW80应该注意控制TW80的浓度。4、从石油污染土壤中扩繁出的AMF混合菌群及其中的单一菌种与玉米联合均能促进土壤芘污染的修复，原始混合菌群具有明显的种群优势，其与玉米联合修复土壤芘污染的效果最佳。1mg/kg、10mg/kg和50mg/kg芘处理土壤中，玉米接种混合菌种M4(Glomus intraradices， Glomus mosseae， Glomus etunicatum和Arcaulospora tuberculata)处理土壤的芘残留浓度分别为0.12mg/kg，0.54mg/kg和3.92mg/kg，分别比接种单一菌种M1处理降低了32.6%，58.6%和42.2%，比接种单一菌种M2(G.intradices)处理降低了28.1%，59.9%和36.6%，比接种复合菌种M3(G.intradices+G.mossea)处理降低了2.7%，55%和23.5%。5、从石油污染土壤中扩繁出的混合AMF菌群在无原始条件下的整体扩繁会改变菌群的组成及其结构，并会对菌群与玉米联合修复土壤芘污染的功能产生不利影响。
