Process and electrolysis device for removing heavy metals in domestic garbage organic waste

Abstract

The invention discloses a process and an electrolyzer for removing heavy metal in organic waste in household garbage. The process comprises seven processes which are sequentially as follows: collecting, transporting and loading of household garbage, sorting of household garbage, mixing and grinding, washing and separating, primary compressing and dehydrating, electrolyzing, and secondary compressing and dehydrating. By virtue of the processes, the household garbage is treated into compost raw materials. The electrolyzer comprises a box body, a positive electrode guide plate, a negative electrode guide plate, a rod type spiral pusher, a speed reducer, a charge tube, a discharge tube and a precipitate discharge hole. The process is scientific in conception, eliminates the problem that environment is polluted by heavy metal due to the fact that organic waste in household garbage is used for composting, saves operation cost in comparison with other physical or chemical treatment methods, improves compost fertilizer efficiency, is stable in operation, and is simple and convenient to operate.

Description

technical field

[0001] The invention relates to the technical field of garbage treatment, in particular to a process for removing heavy metals in domestic garbage organic waste and an electrolysis device thereof. Background technique

[0002] Heavy metals in the organic waste used for composting in the recycling of municipal solid waste are the main substances that affect the environment, and also affect the efficiency of composting. How to effectively remove heavy metals from organic matter used for composting is a hot topic in municipal engineering and environmental protection research. It is also a great difficulty for compost manufacturers and threatens the survival and development of enterprises. Conventional heavy metal removal methods generally change the form of heavy metals in compost products, such as solidification and stabilization technology, while the total amount of heavy metals in fertilizers has not changed. During use, heavy metal ions may also change forms...
