Countryside solid waste aerobic fermentation integration device

Abstract

The invention relates to a countryside solid waste aerobic fermentation integration device, which comprises a compost fermentation bin, wherein the axial line inside the bin body is provided with a hollow screw drive rod, one end of the hollow screw drive rod is provided with an opening, and the other end of the hollow screw drive rod is closed. The screw drive rod is provided with an air outlet hole, and plural pairs of hollow blades provided with air outlet holes are arranged on the screw drive rod in the opposite direction, wherein the hollow blades are relative to the air outlet hole of the screw drive rod. The bottom of the compost fermentation bin is provided with a garbage percolate collecting pipeline, wherein the garbage percolate collecting pipeline is connected to a waste water treatment device. The top of the compost fermentation bin is provided with a deodorization pipeline, wherein the deodorization pipeline is connected to a condensation tower through an exhaust fan. The condensation tower is connected to a biological filter tank through a stench pipeline, wherein the biological filter tank is connected to the opening end of the screw drive rod through an aerator. The condensation tower is connected with the waste water treatment device through a distilled water pipeline, and an effluent pipeline of the waste water treatment device is connected with the internal of the compost fermentation bin.

Description

technical field [0001] The invention relates to a solid waste composting treatment device, and more particularly relates to an integrated aerobic fermentation device for rural solid waste. Background technique [0002] Taking rural areas as an example, with the continuous development of the rural economy and the continuous improvement of farmers' income levels, the amount of rural solid waste has also begun to increase rapidly. The sources of solid waste in the rural ecosystem are mainly villagers' domestic garbage, livestock manure and sewage. Residual sludge at the treatment station. [0003] According to the survey conducted by the Ministry of Health in 2007, the per capita generation of household waste in China's rural areas reached 0.86kg / (d·person), and the total annual generation was about 300 million t / a. Due to the lack of effective waste management and treatment techniques, about 1 / 3 of rural domestic waste is randomly piled up, seriously polluting the environment...

AI Technical Summary

Problems solved by technology

[0009] The existing solid waste composting treatment equipment mainly includes: tower fermentation equipment, horizontal fermentation drum, silo type fermentation device, belt type stacker turning machine, combined fermentation system, aging equipment, etc. In the prior art, There is no special equipment for rural solid waste treatment

Although these existing solid waste composting treatment equipment can better realize the resource utilization of garbage, from the perspective of economy and management, the existing composting treatment process is not suitable for the treatment of rural domestic garbage, because the traditional aerobic composting mainly The whole process of aeration in the fermentation stage makes the easily degradable substances degrade aerobically, so the oxygen demand is large, the power consumption is large, and the cost is high. It is not suitable for the economic development level of rural areas, and it is difficult to popularize and apply. Most of the treatment facilities do not consider how to deal with the leachate produced during the fermentation process, and the odor during the fermentation process will pollute the surrounding environment
