Example Embodiment

[0020] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0021] According to the construction environment of the landfill, local climatic conditions and many other factors, different methods can be selected to set up gas production wells in the landfill. Usually, vertical gas production wells are used for the landfills that have been closed. The buried site adopts horizontal gas production wells. The following is an example of setting up multiple vertical gas production wells in a landfill. Please refer to figure 1 , figure 1 It is a schematic diagram of a biogas treatment system in a domestic waste landfill according to an embodiment of the present invention. A vertical gas production well 12 is set in the landfill 11, and a gas production pipe 13 is inserted into the gas production well 12, and the gas production pipe 13 is located in the soil of the landfill. In the inner part, the...

Abstract

The invention discloses a method and system for integrated treatment and recycling of domestic garbage landfills. The method includes recycling and recycling methane generated in garbage landfills; adopting circular self-purification treatment for leachate of garbage landfills methods for treatment; ecological restoration of the landfill surface. Through the above technical scheme, the present invention realizes the integrated treatment and recycling of the triple pollution of methane, leachate and solid waste in domestic waste landfills.

Description

technical field [0001] The invention relates to a method and system for integrated management and recycling of domestic waste landfills. Background technique [0002] With the rapid development of China's economy, a large number of people are pouring into cities, the scale and boundaries of cities are constantly expanding, and the process of urbanization is rapid. While we are enjoying prosperity, we are also experiencing the consequences of the deteriorating living environment. On the one hand, the urban population is increasing rapidly, and domestic garbage is also increasing sharply. The treatment method of urban garbage in my country is still relatively backward. The main method is landfill, about Accounting for more than 95% of the entire garbage disposal method; on the other hand, the landfill method adopted in our country is basically a random stacking method without harmless treatment, and the garbage landfill that was originally on the edge of the city is becoming a ...
