[0002] With the continuous improvement of environmental protection requirements and the sustainable development of the petrochemical industry, the demand for efficient and reliable sewage treatment technology is becoming increasingly urgent. As a common sewage treatment method, the activated sludge method has been widely used in the petrochemical industry. Activated sludge is composed of a large number of microorganisms, organic matter and inorganic substances. Through the metabolism of microorganisms, it can effectively remove organic matter, nitrogen, phosphorus and other pollutants in sewage. However, petrochemical sewage contains a large amount of difficult-to-degrade organic matter, heavy metals and toxic and harmful substances. These substances have an inhibitory effect on the microorganisms in the activated sludge, reducing the sewage treatment effect. In addition, different types of petrochemical sewage have different water quality characteristics, and it is necessary to select appropriate microbial strains to improve treatment efficiency.

[0003] To address these issues, research is underway to combine proprietary bacteria with activated sludge. These bacteria are microbial strains specifically selected and cultivated for petrochemical wastewater, exhibiting strong degradation capabilities and adaptability. Mixing these bacteria with activated sludge can leverage the strengths of both, improving wastewater treatment efficiency. However, there is currently a lack of efficient reactors specifically designed for mixing petrochemical activated sludge and proprietary bacteria. Existing reactors often fail to meet the specialized requirements of mixing the two, resulting in uneven mixing, low reaction efficiency, and complex operation.

[0004] Therefore, the development of a reaction device for mixing activated sludge and proprietary bacteria in the petrochemical industry has important practical significance and application value.

The main reaction vessel comprises a feed port 7, a feed control valve 6, a discharge port 11, a discharge control valve 10, and a mixing pipe. The feed port and the discharge port 11 are respectively disposed at opposite ends of the mixing pipe. The feed control valve is mounted on the end of the mixing pipe near the feed port, and the discharge control valve is mounted on the end of the mixing pipe near the discharge port. The feeding system is connected to the feed port. The control system includes a pressure gauge 20 mounted on the mixing pipe to detect the internal pressure and a water bath temperature control system to control the internal temperature of the mixing pipe. The pressure gauge 20 is mounted on the straight portion of the pipe to monitor the internal pressure of the mixing pipe in real time. Technical process parameters are adjusted according to the actual pressure conditions to achieve optimal production results. Activated sludge and proprietary bacterial liquid are transported into the mixing pipe through the feeding system. The activated sludge and proprietary bacterial liquid can automatically mix and react during the transportation along the mixing pipe. This design can automatically close the check valve to prevent the liquid in the pipeline from flowing back, while maintaining the working pressure of the feeding system during operation, thereby improving the overall stability. In addition, the feed control valve and the discharge control valve are arranged at both ends of the mixing pipe to control the inlet and outlet of the mixing pipe so that it can be fully mixed, thereby ensuring that the activated sludge and proprietary bacterial liquid reach the expected mixing ratio and quality in the mixing pipe.

[0021] During operation, feed lines 1 and 2 deliver activated sludge and proprietary bacterial solution to an S-shaped mixing pipe. Feed pumps and flowmeters installed on these pipes control the flow rates from both lines, precisely adjusting the mixing ratio of activated sludge and proprietary bacterial solution. Once in the mixing pipe, the activated sludge and proprietary bacterial solution are thoroughly mixed before flowing out the discharge port. To ensure uniform mixing, the mixing pipe is equipped with a water bath jacket and a constant temperature water tank, providing heating and cooling to ensure normal operation under various environmental conditions.

[0022] like Figure 1 The mixing pipe shown is composed of a straight pipe 8 and a curved pipe 9. There are several straight pipes and curved pipes, wherein the number of straight pipes is one more than the number of curved pipes, and two adjacent straight pipes are connected by a curved pipe.

The water inlet pump is installed on the water inlet pipeline, one end of the water outlet pipeline is connected to the outer wall of one end of the water bath jacket near the discharge port and is connected to the water storage cavity. The water outlet pump is installed on the water outlet pipeline. The water inlet pipeline and the other end of the water inlet pipeline are both connected to the constant temperature water tank. A control panel for controlling its temperature is provided on the outer wall of the constant temperature water tank. The temperature sensor is arranged in the straight pipe and electrically connected to the control panel. The utility model ensures stable operation of the mixing pipe under constant temperature conditions by circulating water in the water bath jacket, reducing the impact of temperature fluctuations. According to actual needs, the water bath jacket can heat or cool the medium inside the pipe to meet the temperature requirements under different conditions.
