Method and special apparatus for refuse leachate disposal

Abstract

The invention discloses a method of treating garbage seeping liquid and a special device thereof. The device of treating the garbage seeping liquid provided by the invention comprises two garbage reactors 1 connected in series and a garbage reactor 2. The garbage reactors 1 and the garbage reactor 2 comprise a pool body, a water distribution device and a vent-pipe. The top part of the pool body is open and the bottom is provided with a through hole. The water distribution device is used for leading the garbage seeping liquid towards the pool body. The vent-pipe is arranged vertically in the tank body to be used for the ventilation. The application of the device of treating the garbage seeping liquid of the invention can realize the sustainable yield of a garbage land fill filed, and achieve the zero draining purpose of the seeping liquid.

Description

technical field [0001] The invention relates to a method and a special device for treating landfill leachate. Background technique [0002] Landfill leachate has the characteristics of complex water quality, large fluctuations in water volume, and high content of toxic and harmful substances. So far, almost all sewage treatment methods have been used to treat leachate, but most of them encounter problems such as difficulty in reaching water standards, high treatment costs, and poor system stability. Regardless of the treatment technology used, the leachate problem is affected by waste stabilization, and the longer the waste stabilization period, the longer the leachate treatment cycle. Leachate treatment has become a worldwide problem in the daily management of landfills. [0003] Traditional sanitary landfills focus on: (1) limit the moisture content of the garbage entering the landfill to minimize the leachate produced by the garbage; (2) to prevent the leachate from pol...

AI Technical Summary

Problems solved by technology

Although bioreactor landfills have many advantages, there are also the following problems: 1) operations such as temperature rise, pH adjustment, and inoculation increase operating costs; Failure to adjust the pH value will easily lead to the prolongation of the acidification period and affect the stabilization process of the entire landfill unit; 3) Under the anaerobic landfill process, there is a problem of ammonia nitrogen accumulation in the long-term leachate recharge, especially in the late leachate The concentration of ammoniacal nitrogen is particularly high; 4) After the recharge process, there is still a high concentration of leachate that needs to be treated, and zero discharge cannot be achieved

[0005] However, the nature of landfill waste in Japan is different from that in my country. Its waste is mainly waste incineration ash with a very low content of organic matter, while the content of organic matter such as kitchen waste in waste in my country is very high. Moreover, despite the reduction in quasi-aerobic landfill Increased leachate discharge, but still unable to achieve zero discharge
