Embodiment Construction

[0020] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0021] refer to figure 1 , figure 2 , the anaerobic processor of the present invention is formed by connecting a first UASB reactor 3 and a second UASB reactor 4 in series. Divided by function, the reactor is divided into 5 zones from bottom to top: mixing zone 16, first anaerobic zone 10, second anaerobic zone 11, precipitation zone 12 and gas-liquid separation zone 1.

[0022] Mixing zone 16: The water inflow from the bottom of the reactor, the granular sludge and the mud-water mixture returned from the gas-liquid separation zone are effectively mixed in this zone before entering the anaerobic reaction zone. The bottom is provided with an inlet pipe 7 for bean clear water, and its feed is controlled by a feed pump and an electromagnetic flowmeter 4, and an anaerobic tank feed mixer 2 can also be added on the feed pipeline for pre-mixing...

Abstract

The invention discloses novel high-efficiency anaerobic treatment device for soybean protein wastewater, which comprises a mixing zone, an anaerobic generating zone, a gas-liquid separation zone and a settling zone, wherein the mixing zone is used for mixing inflow water and granular sludge at the bottom of a reactor as well as a sludge-water mixture returned from the gas-liquid separation zone; after the sludge-water mixture formed in the mixing zone enters the anaerobic generating zone, organic matters are converted into methane under the action of high-concentration sludge, and the sludge-water mixture is lifted to the gas-liquid separation zone by methane; in the gas liquid separation zone, methane in the lifted mixture is separated from the sludge-water mixture and then is stored, and the sludge-water mixture returns to the mixing zone along a backflow pipe; in the settling zone, solid-liquid separation is carried out on the sludge-water mixture from the anaerobic generating zone; and the mixing zone comprises a tank body, multiple cyclone water distributors connected with water inflow pipes are arranged in the tank body, each cyclone water distributor is provided with multiple nozzles, and the water outflow direction of each nozzle is identical to the tangential direction of the inner wall of the tank body. According to the invention, the mass transfer effect in the reactor is improved and the reactor treatment effect is optimized.

Description

technical field [0001] The invention relates to an anaerobic processor, more precisely, relates to an anaerobic processor for treating soybean protein moisture. Background technique [0002] Due to its huge processing capacity and potential application prospects, wastewater anaerobic biotechnology has always been a hot spot in the research of water treatment technology. From the traditional anaerobic contact process to the widely popular UASB process, the anaerobic treatment technology of wastewater has become increasingly mature. As the contradictions between production development and resources, energy consumption, land occupation and other factors become more prominent, the existing anaerobic process is facing severe challenges, especially how to deal with a large amount of high-concentration organic wastewater brought about by production development. A more optimized anaerobic process in terms of technical economy is very necessary. The internal circulation anaerobic t...
