Problems solved by technology
[0003] When ABR is used for the treatment of domestic sewage with good biodegradability, granular sludge is easy to form in the reactor; but when it is used for industrial wastewater treatment, even if granular sludge is used for inoculation, the granular sludge will gradually break down during operation, and It is taken out of the reactor by the wastewater, resulting in the deterioration of the effluent quality, which makes it difficult for ABR to achieve good treatment results in industrial wastewater treatment

Embodiment Construction
[0038] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0039] The cage packing type anaerobic-anoxic-aerobic treatment device for beer wastewater of this embodiment, such as figure 1 As shown, it includes water storage tank 2, elevated water tank 3, lift pump 1, ABR reaction tank 12, anoxic reaction tank 13, aerobic reaction tank 14, cage packing 9 and aeration device;
[0040] The water storage tank 2, the ABR reaction pool 12, the anoxic reaction pool 13 and the aerobic reaction pool 14 can all be built as underground structures, and the ABR reaction pool, the anoxic reaction pool and the aerobic reaction pool must be underground structures or above-ground structures at the same time. In order to maintain the reaction temperature and reduce the land occupation, especially in the northern region, it can reduce the adverse effects of freezing damage and low temperature on biochemical treatment; the top of th...

Abstract
The invention provides a cage-shaped filler type device for treating beer waste water in an anaerobic-anoxic-aerobic mode and a method for treating bear waste water by using the device. The device comprises a water storage tank, a high-mounted water tank, a lifting pump, an ABR (anaerobic baffled reaction) tank, an anoxic reaction tank, an aerobic reaction tank, a plurality of cage-shaped fillers and an aerating apparatus; the water storage tank is arranged at one side of the ABR tank; the lifting pump is arranged in the water storage tank; the high-mounted water tank is arranged above the water storage tank; the high-mounted water tank is connected with a water inlet of the ABR tank by a pipeline; the anoxic reaction tank is arranged at one side of the ABR tank; the aerobic reaction tank is arranged at one side of the anoxic reaction tank; the anoxic reaction tank and the aerobic reaction tank are connected by an overflow pipe; and the cage-shaped fillers are arranged in the ABR tank, the anoxic reaction tank and the aerobic reaction tank. By using the method for treating beer waste water by using the device, high COD (chemical oxygen demand) removing rate, SS (suspended solid) removing rate and ammonia nitrogen removing rate and excellent impact-resistant loading ability are achieved; in addition, the whole device is simple in structure, low in treating and building costs, convenient to manufacture and beneficial to the waste water treatment of breweries in different scales.
Description
technical field [0001] The invention relates to the technical field of reactors, in particular to a cage packing type anaerobic-anoxic-aerobic treatment device and method for beer wastewater. Background technique [0002] In the anaerobic biological treatment of wastewater, relatively mature processes mainly include anaerobic biological filter (AF), internal circulation anaerobic reactor (IC), upflow anaerobic reactor bed (UASB), baffle reactor ( ABR) etc. Anaerobic Baffled Reactor (ABR Reactor for short) is a new type of high-efficiency anaerobic reactor developed by Professor Mc. Carty and others in the United States. It has the characteristics of simple structure and strong sludge retention capacity. . A plurality of baffles are set in the reactor to divide it into multiple cascaded reactors, and the waste water to be treated is baffled up and down along the cascaded reaction chambers, and at the same time, the reaction medium of the reactor is uniformly mixed and forme...
