Embodiment 1

[0022] Such as figure 1 As shown, a harmless treatment process for domestic waste leachate, this process deposits and stratifies the sewage in domestic waste, which can be divided into grease layer, sewage layer and sludge layer. The specific process steps are as follows:

[0023] ①. The domestic waste is filtered through the filter device to filter the dirty liquid in the domestic waste into the storage tank 1, and the peculiar smell in the dirty liquid is removed by the multi-charged ion deodorization device 5. While deodorizing, the dirty liquid will automatically Sedimentation, after sedimentation, it can be divided into three layers. The oily liquid floats on the uppermost layer of the sewage, the sewage is located in the middle layer, and the bottom layer is sludge;

[0024] ②. First use the oil pump 2 to pump the liquid containing grease in the uppermost layer into the distillation system 8 for processing into lubricating oil;

[0025] ③, secondly use the sewage pump 3...

Abstract

A disclosed domestic waste leachate harmless treatment method is characterized in that: the soiling solution in the domestic waste is subjected to deposition layering and is divided into a grease layer, a sewage layer and a sludge layer which are respectively drawn out by an oil pump, a sewage pump and a sludge pump; grease is transferred to processing center and processed into lubricating oil; sewage is filtered, the filtered-out dirty slag is stirred with adobe materials for preparation of adobes, and the filtered sewage is discharged into a kiln for evaporation; and the sludge is prepared into adobes by a brickmaking machine and transferred into the kiln and further sintered into bricks. The technology of the invention is simple and clear, convenient to operate, low in cost and fast in effectiveness, and can be used for layering treatment on the soiling solution of the domestic waste and harmless treatment and utilization on the layered liquids.

Description

technical field [0001] The invention relates to a domestic waste treatment process, in particular to a harmless treatment process for domestic waste leachate. Background technique [0002] Most of the garbage in many cities in our country is still piled in the open air without any protective measures. Every garbage dump has become a source of pollution. Mosquitoes and flies are born, rats are infested, the smell is everywhere, and a large amount of garbage and sewage seeps from the surface into the ground, causing serious pollution to the urban environment and groundwater sources. [0003] From the current market analysis, the treatment of domestic waste can be divided into three types. First, landfill treatment: that is, landfill is an effective method to consume a large amount of urban domestic waste, and it is also the final treatment method for all waste treatment process residues. At present, my country The direct landfill method is widely used; 2. Incineration treatmen...
