Effect of garbage-compact density on the stabilizing process of laboratory-simulating semi-aerobic landfill with leachate recirculation;

We draw a conclusion that landfill leachate recirculation is a effect.

According to the problems of the combined scheme and in site scheme, the idea of using leachate recirculation technology to implement the two schemes was proposed.

This paper mainly introduces the application status of geothermal power at home and abroad,the principle and main mode of geothermal electricity,the compilation of standard for geothermal electricity,and the technical problems such as reinjection,corrosion and scaling of geothermal field.

During geothermal reinjection,chemical monitoring can enable unfavorable changes in the reservoir to be seen in advance.
