Complete equipment for preparing aqueous solution fertilizer from household classified kitchen garbage

Abstract

The invention discloses complete equipment for preparing an aqueous solution fertilizer from household classified kitchen garbage, which belongs to the field of organic solid waste Chinese kitchen waste resourceful treatment equipment. The device comprises a garbage can lifting and dumping machine, a crusher, a pulping machine, a reaction tank, a rotary screen, a hydrolysis tank, a grinding machine, a centrifugal machine, a filtering machine, a dosing machine, a vacuum evaporation and concentration unit, a stabilizing unit and a metering and filling machine, wherein a temporary storage tank connected with an inlet of the crusher is arranged at an outlet of the garbage can lifting and dumping machine; and an outlet of the crusher is connected with an inlet of the pulping machine. The complete equipment for preparing the aqueous solution fertilizer from the household classified kitchen garbage is small in occupied area, high in treatment efficiency, free of wastewater discharge, waste gas discharge, stink and peculiar smell in the treatment process, small in application amount, good in application effect and capable of effectively improving soil and improving the quality of agricultural products, and is a high-added-value aqueous solution fertilizer product capable of recycling and turning waste into wealth.

Description

technical field [0001] The invention belongs to the technical field of organic solid waste and kitchen waste recycling treatment equipment, and in particular relates to a complete set of equipment for making aqueous solution fertilizer from household sorting kitchen waste. Background technique [0002] At present, there are basically two treatment methods for kitchen waste that are forced to be sorted by households. One is aerobic fermentation, followed by solid-water separation. The sewage is treated with organic sewage, and the separated residue is then landfilled or incinerated. The fermentation time is long and produces waste. Secondary pollution of greenhouse gases, especially odor pollution. This method is actually reduction, not harmless. Another method is anaerobic fermentation to produce biogas, biogas slurry, and biogas residue. Gas-fired power generation after biogas purification, biogas slurry is used for high-concentration organic sewage treatment, it is diffi...

AI Technical Summary

Problems solved by technology

This method also has a fermentation time as long as one to two months, and greenhouse gas pollution is generated during the fermentation process, especially odor pollution.

The investment of this method is greater than the income of power generation
