Embodiment Construction

[0013] The technical scheme of the present invention will be further described below in conjunction with the drawings.

[0014] Such as Figure 1~3 As shown, the present invention is suitable for an oxygen-enriched bioreactor reactor for in-situ restoration of micro-polluted water bodies. The outside of the reactor is a stainless steel tube rectangular frame structure. The reactor is directly installed in the micro-polluted water body and the floating island floating technology is used (in There are pontoons 2) installed on both sides of the rectangular frame 1 so that the whole reactor can fluctuate with the water level without affecting the flood passage of the river. In addition, the shape of the reactor frame imitates the design of a bridge pier, thereby reducing the impact of the device on the hydraulic flow in the river. In the reactor, the aeration hollow membrane unit 4 and the biological filler unit 5 are arranged left and right along the water flow direction, and there ...

Abstract

The invention discloses an oxygen-enriched biological reactor suitable for in-situ remediation of a micro-polluted water body, which comprises a rectangular frame, an aquatic plant floating island unit fixed at the top of the rectangular frame, and an aeration hollow membrane unit and a biological filler unit which are fixed in the rectangular frame, wherein each aeration hollow membrane unit comprises an aeration branch pipe connected with an external aeration pipe; the aeration branch pipes are arranged at the bottom of the aeration hollow membrane unit at equal intervals, each aeration branch pipe is communicated with a plurality of air inlet pipes, each air inlet pipe is correspondingly connected with a hollow membrane, and the hollow membranes are suspended in the rectangular frame through brackets; and the biological filler unit comprises a plurality of vertically suspended biological fillers. The oxygen-enriched biological reactor is suitable for in-situ remediation of micro-polluted water, the number and activity of microorganisms are improved by improving the content of dissolved oxygen in the water, and therefore the oxidation and nitrification effects of the microorganisms are enhanced, and the concentration of pollutants in the water can be reduced.

Description

Technical field [0001] The invention relates to a reactor, in particular to an oxygen-enriched bio-reactor suitable for in-situ restoration of micro-polluted water bodies. Background technique [0002] Water bodies whose organic content and some water quality indicators exceed Class III standards of the Environmental Quality Standards for Surface Water (GB3838-2002) are generally called micro-polluted water. Advanced treatment technology is currently a hotspot of research and attention in the field of micro-polluted water treatment, and it is also one of the most effective countermeasures to deal with the increasingly serious pollution of surface water sources, to ensure that the effluent from water plants meets the standards, and to ensure the safety of drinking water. Bioremediation technology is considered to be the most scientific, effective and economical water restoration technology. Bioremediation technology mainly uses the metabolic activities of microbial populations to...
