The beneficial effects of the utility model are:
1. compare with the traditional IC reactor, have only the one-level triphase separator, greatly reduce height for reactor, reduced cost.
2. compare with traditional UASB reactor, use the biogas that self the produces realization internal recycle that is used as power, reduced working cost.
3. use injector as circulation device, internal circulating load is big, whole circulation system movement-less part, reliable operation.
4. use filtering net protection injector jet pipe inlet mouth, make it not blocked, guarantee that system is reliable.
5. system's service intermittent.Have only when having accumulated abundant biogas, system just moves, and quantity of circulating water is directly proportional with biogas output, can not cause recycle system paralysis because of biogas output is few.
6. intensity of circulation is controlled, and running situation is observed convenient.System's service data can deposit computer in immediately, is convenient to adjust operating parameter.
7. system elementization, the unit individuality is little, in light weight, economical with materials, the reactor of adaptation Any shape, installation and transportation are convenient.
8. bigger suspended solid is blocked under the filtering net in the sewage, sinks automatically after the hydrolysis, simultaneously because liquid level change periodically up and down in the gas skirt can not cause the scum silica frost crust.
