Background technology
The house refuse of samll cities and towns and rural area is little because of its generation, discharges characteristics such as dispersion, is difficult to adopt the conventional treatment method of domestic waste scale, so present samll cities and towns and rural area mainly adopt modes such as easy compost and landfill to handle.But there is operation in these modes and moves extensively, and sanitary condition is poor, and secondary pollution is bigger, can not reclaim problems such as biomass energy, is unfavorable for the protection of rural ecological environment.In view of samll cities and towns and vast rural area economic and technique level are backward relatively, the equipment of handling house refuse is deficient, therefore be badly in need of cheap, efficiently, middle-size and small-size domestic rubbish disposal equipment easily.
Summary of the invention
The utility model provides a kind of anaerobism-accurate aerobe reactor of handling house refuse, has simple operation, advantages such as energy consumption is low, small investment, stabilizing take weak point, recyclable methane.
The utility model solves the technical scheme that its technical problem adopted:
A kind of anaerobism-accurate aerobe reactor of handling house refuse is made up of a plurality of bioreactors unit and 1 public regulating reservoir, around wherein the bioreactor unit is arranged in, in the middle of public regulating reservoir is arranged in; Each bioreactor unit is made up of percolate discharge guiding pipe, leachate recirculation pipe, perforation ventilation duct, water-locator, gas skirt, water seal, and each bioreactor unit is followed successively by geotextiles A, graded gravel layer, geotextiles B, waste layer, old rubbish cover layer from bottom to top; In each bioreactor unit; Vertically ventilation duct inserts by the reactor middle part is vertical; And be connected with the bottom level ventilation duct, bottom level ventilation duct two ends all and air communication, water-locator is placed on the old rubbish and is connected with the leachate recirculation interface tube with flexible pipe; Percolate discharge guiding pipe is connected to regulating reservoir and is in the slack flow state, and the percolate discharge guiding pipe delivery port is higher than the regulating reservoir water surface and and air communication.
Perforation ventilation duct and percolate discharge guiding pipe all adopt big-diameter pipeline, caliber >=110mm; Water-locator is detachable.
During the house refuse filling, all pipeline valves are opened, made bioreactor unit and air communication, house refuse is carried out aerobic degradation.After filling finished, the top layer adopted old rubbish to cover, and water-locator was placed on the old rubbish also be connected with the leachate recirculation pipe joint with flexible pipe, and gas skirt is installed, and closed ventilation duct and percolate discharge guiding pipe valve, made house refuse carry out anaerobic degradation.Before recharging percolate, open the percolate discharge guiding pipe valve earlier at every turn, percolate is imported regulating reservoir, close the discharge guiding pipe valve after the percolate discharging finishes; Open leachate recirculation tube valve and submersible sewage pump subsequently, implement leachate recirculation, close leachate recirculation tube valve and submersible sewage pump after recharging end.The domestic refuse anaerobic degradation efficiency with ventilation duct, percolate discharge guiding pipe valve opening, takes off gas skirt after obviously descending; Form internal-external temperature difference through the inner biodegradable heat in bioreactor unit and produce power; Impel air to pass through ventilation duct and percolate discharge guiding pipe, and upper epidermis to get into the rubbish body inner, form the environment of aerobic-anoxic-anaerobism in the bottom, around top layer and the ventilation duct; House refuse is degraded under double oxygen environment, further promote the stabilisation of house refuse.Discharging after house refuse is become thoroughly decomposed fully, the old rubbish of part gives over to covering layer material.
Around bioreactor unit more than 2 is arranged in,, not only make things convenient for the percolate guide and recharge, also can reach the effect that the percolate of different degradation period dilutes each other, neutralizes, inoculates simultaneously at 1 public regulating reservoir of intermediate arrangement.A plurality of bioreactor units alternately operations, continuous, the circular treatment of realization house refuse.Only, when first bioreactor unit enforcement phase I is recharged, carry out percolate pH adjusting and inoculation, after this no longer implement this operation in first cycle.
