Gas exhausting and injecting well device for aerobic bioreactor process

Abstract

The invention provides a gas exhausting and injecting well device for an aerobic bioreactor process. The gas exhausting and injecting well device is characterized in that the surface of a garbage heapis drilled downwards to form a gas well, a well pipe is inserted into the gas well, the top of the well pipe stretches out of the ground by 0.5 m to 1.0 m and is connected with a horizontal branch pipe through a manifold branch, a bidirectional pressure gauge capable of displaying positive and negative pressure and a gas sampling valve are mounted at the top end of the well pipe, and pressure andgas ingredients in the well can be analyzed in real time; and the well pipe is a PE or HDPE pipe of De 75 mm to 150 mm. According to the gas exhausting and injecting well device, by designing the structure of the well pipe, the ubiquitous problems that gas exchange at different depths of the garbage heap is uneven, a temperature sensor cannot fast and sensitively reflect the real-time temperature, and a sleeve needs to be additionally arranged are solved; and the effects that gas exhausting and injecting wells are tightly closed, gas exchange is smooth, construction is simple, control is easy, and the temperature, the pressure, the gas ingredients and the like can be monitored in real time are achieved, and the aerobic treatment technology is more mature and efficient.

Description

technical field [0001] The invention relates to the technical field of aerobic restoration of garbage landfills in environmental engineering, in particular to a pumping and injection gas well device used in aerobic bioreactor process of garbage landfills. Background technique [0002] With the advancement of industrialization and urbanization, the scale of the city is getting bigger and bigger. The waste landfill at the edge of the city has gradually become the central area of ​​the city. The development and utilization of its surrounding areas have made the commercial value of the original waste landfill gradually. highlight. On the other hand, due to historical reasons, many waste landfills built at the end of the last century were often not regulated due to technical and financial reasons, and even did not take certain pollution prevention and control measures, resulting in more and more waste being filled and pollution problems becoming more and more serious. It will ca...

Problems solved by technology

[0006] The purpose of the present invention is to provide a kind of pumping and injecting gas well device for aerobic bioreactor process in view of the existing aerobic bioreactor technical level, to overcome the inhomogeneity and temperature of gas exchange at different depths of garbage dumps in the prior art. The sensor needs to be equipped with another casing, and gravel and gravel should be lowered before the downhole pipe is easy to cause damage to the well wall, etc., and the opening size and proportion of the flower pipe are explained in detail, which has the advantages of simple construction, fast and efficient, strong adaptability, It is convenient for process dynamic monitoring and other advantages
