Embodiment 1

[0064] 1. Implementation process

[0065] In this example, the oily wastewater treatment system of a refinery is applied. After a series of deoiling treatments including a circular grease trap, an adjustable oil removal tank, vortex air flotation, and dissolved air flotation, the wastewater enters a compact biological reaction tank for biochemical treatment. deal with. The mud-water mixture in the biological reaction tank is pumped into the cyclone carbon release device for cyclone breaking treatment, which improves the mass transfer efficiency of the microbial cells in the sludge flocs and the carbon source, nutrients and dissolved oxygen in the water body, and improves the sludge activity. At the same time, the extracellular polymers in the sludge flocs are released, the carbon source is supplemented, the ΔSCOD (Δsoluble chemical oxygen demand) increases by 15%, the biochemical treatment is strengthened, and the residual oxygen in the anoxic section of the compact bioreactor...

Abstract

The invention relates to a vortex strengthening method and device for compact anaerobic / aerobic process wastewater treatment, and provides the vortex strengthening method for compact anaerobic / aerobicprocess wastewater treatment. The method comprises the following steps: (A) performing vortex treatment on compact anaerobic / aerobic process wastewater to release organic matter; (B) returning the wastewater containing the organic matter obtained in step (A) to an anaerobic zone of a compact anaerobic / aerobic process for degradation so as to reduce dissolved oxygen in the anaerobic zone. The invention further provides a vortex strengthening device for the compact anaerobic / aerobic process wastewater treatment.

Description

technical field [0001] The disclosure belongs to the field of waste water resource treatment, and relates to a method and a device for treating mud-water mixture in a biochemical pool with a combined mechanical and biochemical method, and utilizing the treated product as a resource. Specifically, the disclosure relates to a combination of treating oily wastewater in a compact integrated process environment using a cyclone to treat the mud-water mixture in a biochemical pool to improve activity, promote the release of organic matter, remove dissolved oxygen, and enhance biochemical treatment efficiency. Process and means for effecting the method. Background technique [0002] The activated sludge method has been more than 100 years since it was initiated by E.Arden and W.T.Lockett in England in 1914. The activated sludge method occupies an important position in sewage treatment. In addition to urban sewage treatment, it is also successfully used in industrial wastewater trea...
