A base plate 1 is fixedly provided at the bottom of the biological attenuation tank 2 to realize the maintenance function inside the reactor. The base plate 1 plays a supporting role for the biological attenuation tank 2.

[0025] The bottom of the cylindrical flow guide tube 8 is connected to the top of the biological toxicity detection tank 3, the bottom of the cylindrical flow guide tube 8 inserted into the biological toxicity detection tank 3 is connected to the conical flow guide tube 19, the bottom of the conical flow guide tube 19 is connected to the top of the filling funnel 15, the bottom of the filling funnel 15 is connected to the top of the discharge funnel 16, the bottom of the discharge funnel 16 is connected to the top of the mud discharge pipe 18, and the other end of the mud discharge pipe 18 passes through the sides of the biological toxicity detection tank 3 and the biological attenuation tank 2 respectively.

[0026] A fixed transverse plate 10 is fixedly provided on one side of the inner wall of the biological attenuation tank 2, and a liquid level detector 11 is fixedly connected to the middle part of the fixed transverse plate 10 away from one end of the biological attenuation tank 2. The bottom of the liquid level detector 11 passes through the side of the biological attenuation tank 2, and a support column 17 is fixedly provided on the bottom of the inner wall of the biological attenuation tank 2. The support column 17 is located below the mud discharge pipe 18. The top of the biological attenuation tank 2 is fixedly provided with a top cover plate 9, which is convenient for observing the specific position of the liquid level inside the reactor and ensuring that it has an overflow function when the liquid level inside the reactor is too high. A light-transmitting tube 7 and an observation tube 20 are provided on the outside of the top cover plate 9. There are two light-transmitting tubes 7, which can obtain the biological toxicity of the water sample in real time. The light-transmitting tube 7 provides a directional reaction under suitable light and temperature conditions, and finally decomposes the refractory organic matter in the wastewater through a biological fermentation process, or utilizes the refractory organic matter in the wastewater by targeted biological strains, thereby reducing the biological toxicity in the wastewater and achieving the purpose of pre-attenuation treatment of the biological toxicity of high-concentration organic wastewater.

[0027] The top of the internal reflux pipe 12 is connected to the middle of the discharge funnel 16, and the bottom of the internal reflux pipe 12 is connected to the bottom of the biological attenuation tank 2. An inspection port 14 and a water outlet pipe 21 are respectively provided on one side of the bottom of the biological attenuation tank 2. The inspection port 14 and the water outlet pipe 21 are located on both sides of the bottom of the internal reflux pipe 12. An internal reflux valve 13 is provided in the middle of the internal reflux pipe 12.

[0028] The working principle of a bio-attenuation reactor with a high-concentration organic wastewater bio-toxicity detection function in an embodiment of the present application is as follows: when in use, the reactor can directly accept high-concentration organic wastewater without the need for preliminary chemical strong oxidation energy-consuming and power-consuming pretreatment. The reactor is divided into two major functional areas: a bio-toxicity detection area and a bio-attenuation area. The bio-toxicity detection area is composed of a bio-toxicity detection tank 3, and the bio-attenuation area is composed of a bio-attenuation tank 2. By utilizing the "tank in a tank" principle, it occupies a small area and can directly accept high-concentration organic wastewater without the use of chemical agents, high energy consumption, and power consumption, and without generating chemical sludge or secondary pollution.

[0029] Functional area 1 is the biological toxicity detection area. The reaction area utilizes the principle of cylindrical hydraulic centrifugation. Wastewater enters this area tangentially from the water inlet of the water inlet pipe 6 at a certain speed, and forms a vortex under the multi-flow of the cylindrical guide pipe 8. This vortex allows the sewage to quickly mix, contact, and react with the characterizing model strain for detecting the biological toxicity of the wastewater, and then presents new biological activity. The biological activity reflects the biological toxicity of the water sample. The stronger the biological activity, the weaker the biological toxicity. The biological toxicity of the water sample can be obtained in real time through the observation port 23 of the reactor and the instrument monitoring installation port 22.

[0030] When the wastewater is detected to be non-biologically toxic, the wastewater is discharged to the subsequent anaerobic or aerobic biological treatment unit through the mud discharge pipe 18 at the bottom.

[0031] When the wastewater exhibits a certain biological toxicity, it overflows evenly to the biological attenuation reaction zone of functional area 2 through the overflow weir 5 around the cylinder of the biological toxicity detection tank 3 according to the type and degree of biological toxicity. The biological attenuation reaction zone is customized to cultivate composite bacterial strains according to the characteristics of the wastewater. The bacterial strains are suspended and grown in the attenuation zone. When the overflowing wastewater selectively attaches to the bacterial strains, a directional reaction occurs under the appropriate light and temperature conditions provided by the light-transmitting tube 7. Finally, the wastewater is decomposed through a biological fermentation process, or the targeted biological strains utilize the difficult-to-degrade organic matter in the wastewater, thereby reducing the biological toxicity in the wastewater, achieving the purpose of pre-attenuation treatment of the biological toxicity of high-concentration organic wastewater. The attenuated high-concentration organic wastewater enters the subsequent sewage biochemical treatment unit through the outlet pipe 21.

[0032] The interconnecting function of the internal reflux valve 13 can achieve pressure balance between the biological toxicity detection tank 3 and the biological attenuation tank 2, and realize the reflux and replenishment of strains under necessary conditions to prevent the loss of strains.
