The interlayered-oxidation zone sandstone type uranium deposits correspond spatially to the subzones of the interlayered-oxidation zone.

层间氧化带砂岩型铀矿床在空间上与层间氧化带各亚带的分布具有严格的对应关系。

The study result of microwave irradiation enhanced coagulation process show that the process of irradiating with microwave firstly and then with coagulation is more efficiency to treat oil-containing wastewater than that with coagulation firstly and then with microwave, and when dying wastewater and landfill leachate are treated with microwave irradiation and coagulation process simultaneously, the treatment effects will become better. The study result of microwave irradiation enhanced Fenton oxidation process shows that, no matter what oil-containing wastewater, printing and dying wastewater and landfill leachate, better treatment effect will be achieved with microwave irradiation firstly and then with Fenton oxidation process, with which organic substance and chromaticity can be removed easily.

在微波强化混凝和Fenton氧化组合工艺研究方面，对微波辅助强化混凝工艺而言，处理含油废水时采用先微波预处理再混凝处理的效果较好，而处理染料废水或垃圾渗滤液时采用微波辐射与混凝同时处理的效果较好；对微波辅助强化氧化工艺而言，无论是含油废水、染料废水还是垃圾渗滤液，采用先微波辐射再Fenton氧化处理均可以获得较好的效果，特别适合于有机物的降解以及溶液色度的脱除。
