Embodiment

Embodiment:

Present embodiment is example with karst region rubbish sludge composting.

The good anaerobic sludge garbage compost of a kind of stirring-type Temperature Feedback compound fertilizer facility processed is made up of compost jar and Temperature Feedback regulation system; The compost tank top is provided with inductor block and inserts hole 1, tail gas detects mouth 2 and exhaust collection interface 3, the compost tank top comprises gas skirt 4 and water leg 5, water leg 5 outsides are provided with dewatering outlet 6, flange packing 7 is housed below the water leg 5, compost jar outer upper is provided with opening for feed 8, compost jar outer lower portion is provided with discharge port 12, the inboard upper, middle and lower of compost jar is respectively equipped with dissolved oxygen probe 9 and temp probe 10, compost jar central axial line position is equipped with spiral pushing device 11, spiral pushing device 11 lower ends connect reversing motor 16, be used for the positive and negative twocouese running of control spiral pushing device 11, compost jar intracavity bottom mounting bracket 18, place filler 17 on the support 18, filler 17 tops arrange separation net 15; The Temperature Feedback regulation system comprises aerating apparatus and hot water circulation equipment, and to compost jar intracavity bottom, aerating apparatus comprises air regulator 13 and gas blower 14 to aerating apparatus by pipe connection; Hot water circulation equipment comprises thermal insulation layer 19, recycle pump 20, heating kettle 21 and the hot-water circulation pipe 22 in the compost jar outside, and thermal insulation layer 19 bottoms connect heating kettle 21 by pipeline through recycle pump 20, and heating kettle 21 is connected to thermal insulation layer 19 tops by hot-water circulation pipe 22; The Temperature Feedback regulation system realizes aerobic, the anaerobism alternate run of compost by control aerating apparatus and hot water circulation equipment.

The principle of work of described embodiment device:
