Modified trash storing pit landfill leachate collecting system

Abstract

The invention discloses a modified trash storing pit landfill leachate collecting system. The system comprises a horizontal collecting system, wherein the horizontal collecting system comprises a landfill leachate collecting trench and a plurality of collecting grids which are arranged at the bottom of the side wall of a trash storing pit along the horizontal direction. The system is characterized by also comprising a vertical collecting system, wherein the vertical collecting system is arranged on the side wall of the trash storing pit on the upper portion of the horizontal collecting system. A bottom horizontal collecting system easy to block is modified to the solid collecting system formed by the horizontal collecting system and the vertical collecting system, the landfill leachate in the trash pit can be discharged smoothly under the condition that the construction cost is not increased too much, and the problems that the horizontal collecting system is blocked, loses effect and cannot discharge the landfill leachate due to excessive trash in the trash pit are solved. The load of the trash pit is reduced, the structure of the trash pit is safe and durable, the trash water in an incinerator is reduced, the temperature of the hearth of the trash incinerator is guaranteed, the Dioxins decomposition is facilitated, the burning efficiency is improved, the pollution for the environment due to trash incineration generation is reduced, the efficiency of a trash generator is improved, the energy source can be utilized well and the environment is protected.

Description

Technical field [0001] The invention relates to the field of environmental protection engineering, in particular to an effective collection system for garbage leachate in a garbage storage pit. Background technique [0002] Garbage disposal is a serious problem in the process of urbanization and economic development. Due to the continuous increase in the amount of garbage in modern foreign countries, the original landfills have become saturated or saturated. It is difficult for the development of urban areas to find new landfills. The problem of garbage disposal is becoming more and more prominent. With the increase in the calorific value of waste, waste classification combined with waste incineration power generation is an effective way to realize waste harmlessness, resource utilization, and reduction. [0003] Due to the relatively high water content of garbage in my country, most of the garbage has a water content of 30-40%. In order to facilitate the smooth precipitation of g...

Problems solved by technology

[0004] In the waste incineration power plants that have been built in my country, with the increase in the amount of garbage entering the warehouse, the elevation of the garbage surface in the garbage storage pit is often higher than the elevation of the leachate collection grid at the bottom of the garbage pit, and the leachate grid is in the state of landfill , the landfill leachate col
