Embodiment Construction
[0011] An integrated oxygen-enriched bioreactor, including a horizontal circular reaction tank 001. The circular reaction tank 001 is composed of a left end head 011, a middle reaction zone 012, and a right end head 013. The left end head 011 uses a middle The partition 002 is divided into upper and lower chambers (111, 112). The upper chamber 111 is provided with a top exhaust port 111a and a water inlet I111b. The inner wall of the upper chamber 111 is provided with several blocks for static mixing. The horizontal partition 111c constitutes a gas-liquid mixing chamber. The lower chamber 112 is provided with an air inlet 112a, a water inlet II 112b, and a vent 112c to form an oxygen concentration chamber. The middle partition 002 is provided with several rich Oxygen concentrate disperser 003, distribution pipeline 121 is set in the bottom cavity of the middle section reaction zone 012, water outlet 131 is opened on the right end head 013, and mud-water separator 132 is set in ...

The invention provides an integrated oxygen-enriched bioreactor and belongs to the field of biochemical water treatment. The bioreactor comprises a horizontal round reaction tank, wherein a water inlet I, a water inlet II, an air inlet, an air outlet and a vent nozzle are formed in the left end seal of the horizontal round reaction tank; the right end seal part of the round reaction tank is separated into an upper cavity and a lower cavity; the upper cavity is a gas-liquid mixing cavity, a plurality of horizontal separators for static mixing are arranged on the inner wall of the upper cavity; the lower cavity is an oxygen concentration cavity, and a plurality of dispersers for oxygen-enriched concentrate are arranged on the intermediate separator between the upper cavity and the lower cavity, and are used for concentrating oxygen into a part of reflux liquid and quickly dissolving the oxygen in sewage which is biochemically treated through distribution pipelines in the intermediate biochemical reaction area in the tank body after oxygen and nitrogen in compressed air are separated. A sludge-water separator is arranged in the right end of the reaction tank, so that the sludge generated after biochemical reacting treatment can be separated in the sludge-water separator, and the separated and precipitated sludge moves and flows to the front end of the reaction area through a built-in air stripping pipeline, and appropriate circulation is carried to maintain the concentration.
Description
technical field [0001] The invention relates to the field of biochemical water treatment, in particular to an integrated oxygen-enriched bioreactor utilizing the principle of Henry's law. Background technique [0002] Industrial wastewater treatment, especially high CODcr value, high concentration, refractory organic industrial wastewater treatment, such as chemical, pharmaceutical, coking, leather, printing and dyeing, oil, food and other industries, the prominent problem is serious water pollution, such as conventional If the design process and commonly used equipment technology are used, the process flow is long, the investment in pre-treatment is large, and it is difficult to achieve the technical indicators of biodegradability, which leads to long follow-up biochemical process flow, large land occupation, large investment, and energy consumption. If it fails to meet the standard, it will face the problem of upgrading and reforming. Contents of the invention [0003] ...
