Further, the annular filter tank includes annular canister body case, is symmetrically equipped in the annular canister body case
Two groups of supporting layers for carrying control valve are equipped with recoil between every group of supporting layer filled with filtrate, the top of the annular filter tank
Wash out water pipe.
Further, the anaerobic ammonia oxidation reactor is externally provided with the air blast with being connected inside anaerobic ammonia oxidation reactor
Machine.
Further, the bottom of the anaerobic ammonia oxidation reactor and clear water reserviors is equipped with mud discharging mouth.
Further, it is equipped with control valve on each pipeline.
Kitchen garbage is added to anaerobic fermentation tank from feed tank and carries out anaerobic fermentation, the biogas of generation when the utility model is used
It collects to tank for sewage gas, fermented supernatant fluid flows through annular filter tank by gravity water outlet, and filtering layer retention suspended particulate is effectively gone
Except substantial amounts of COD, filtrate enters anaerobic ammonia oxidation reactor afterwards, by added into tank body nitrite nitrogen, nutriment and
Trace element realizes the efficient removal of total nitrogen under the action of anaerobic ammonia oxidizing bacteria, and anaerobic ammonia oxidation effluent flows into clear water reserviors, clearly
Pond water storage backwashes for annular filter tank.The filter type of the utility model filters for gravity stream, and additionaling power is not required,
Financial cost is saved, filtering tank uses annular design, can increase filter area, reduces filtering load, has in annular filter tank
Two independent Sand Filtration Systems, can run simultaneously, can also be controlled by valve and realize independent operating, maintain easily maintenance, led to
The efficient removal of suspended solid can be realized by crossing the anaerobic fermented liquid of sand filtration, while sand filtration can also adsorb substantial amounts of organic matter,
The influence that organic matter reacts follow-up Anammox is substantially reduced, annular filter device is carried out using anaerobic ammonia oxidation effluent
Backwash, can save substantial amounts of water resource and operating cost.
