Landfill leachate bioreactor based on modified fiber filler

Abstract

The landfill leachate bioreactor comprises a reaction box, a water outlet in the lower portion of the right side of the reaction box is fixedly connected with the water inlet end of a lifting pump, and the water inlet end of the lifting pump is fixedly connected with a water inlet of an electrolytic treatment device. According to the landfill leachate bioreactor based on the modified fiber filler, a water inlet pipe is connected with a leachate outlet pipe, a driving motor II drives a rotary water injection pipe to rotate through the rotary water injection pipe, and a flow equalizing pipe rotates along with the rotary water injection pipe, so that leachate in the flow equalizing pipe can be discharged downwards through a drainage hole while the flow equalizing pipe rotates; the flow equalizing pipe is changed from static leachate discharge to rotary residual filtrate discharge, so that the position of the flow equalizing pipe is in a continuously changing state, and the leachate is more uniformly and comprehensively distributed when entering the reaction box; further, the filter material is in full and comprehensive contact with the upper layer modified zizania aquatica shell fiber filter material structure and the lower layer coconut shell fiber filter material structure.

Description

technical field [0001] The invention relates to the field of landfill leachate biological treatment, in particular to a landfill leachate bioreactor based on modified fiber filler. Background technique [0002] With the continuous development of cities in our country, the output of garbage has also increased. At present, the methods for garbage disposal are mainly incineration, composting and landfill. Among them, the sanitary landfill method has been widely adopted by countries all over the world due to its advantages of low cost, simple treatment, no secondary pollution, and remarkable environmental protection effect. However, during the garbage accumulation process in sanitary landfills, a series of biological decomposition and physical and chemical processes are produced to produce a leachate with complex components and high toxicity, which will cause great damage to the environment. Therefore, it is very necessary to treat landfill leachate. of. [0003] Landfill leac...

AI Technical Summary

Problems solved by technology

[0005] Landfill leachate contains more organic matter, inorganic matter, germs, etc., and it contains foul odor inside, and the color of the leachate is also darker. The existing garbage Leachate bioreactor, in the process of use, cannot specifically oxidize organic or inorganic substances in leachate, and cannot achieve the purpose of disinfection, oxidation or decolorization, and its structure is not optimized and its design is not reasonable enough
