[0002] Industrial wastewater refers to wastewater and waste liquid generated by industrial production. Industrial wastewater is of various types and complex in composition. Most industrial wastewater contains a variety of toxic substances. If discharged directly, it will pollute the environment and cause great harm to human health. Therefore, it is necessary to develop comprehensive utilization, turn harm into benefit, and take corresponding purification measures according to the pollutant components and sewage concentration in the sewage before it can be discharged.

[0003] In the related technologies, the treatment of industrial wastewater is to first perform a simple preliminary filtration, and then treat the floating objects in the wastewater. The graded treatment not only affects the efficiency of the treatment, but also requires the machine to be shut down after the debris is separated, and then the filtered debris is treated. This method is relatively inefficient and affects the normal operation of the wastewater treatment. At the same time, the wastewater is generally treated by manually adding chemicals to the wastewater. The amount of chemicals added is mainly determined based on manual experience. The proportion of multiple chemicals is inaccurate when they are manually added, and it is impossible to add the corresponding chemicals according to the actual situation of the wastewater, that is, it is impossible to carry out targeted treatment for wastewater of different water qualities, and thus it is impossible to ensure that the wastewater treatment effect is optimal.

[0054] In the present invention, preferably, a retractable bellows 18 is fixedly connected to the end of the injection pipe 10, and one end of the bellows 18 away from the injection pipe 10 is connected to a pipe for transmitting industrial sewage. The stretching length of the bellows 18 is several times greater than the distance between the injection pipe 10 and the sewage transmission pipe.

[0057] Specific principle: When using,

[0058] In the first step, the industrial sewage transmission pipeline is connected to the injection pipe 10 through the corrugated pipe 18, and the sewage is discharged from the injection pipe 10 to the corresponding separation cylinder 5, such as Figure 1 As shown, sewage and impurities, floating objects and other debris therein enter the filter cartridge 6, the motor Ⅰ82 drives the driving gear Ⅰ83 to rotate, the driving gear Ⅰ83 drives the driven gear Ⅰ85 meshing therewith to rotate, so that the rotating shaft 84 follows the rotation and drives the driving sprocket 86 to rotate, the driving sprocket 86 rotates the driven sprocket 87 through the chain 88 and drives the filter cartridge 6, the filter cartridge 6 rotates to accelerate the sewage to pass through and separate through the centrifugal force, the sewage and the debris therein are separated, the sewage is discharged from the discharge pipe 7 into the bottom of the separation chamber 1, the debris is concentrated in the filter cartridge 6, there is no need to grade and clean the impurities and floating objects, all of which are separated from the sewage in the filter cartridge 6, and the treatment efficiency is improved;

[0059] In the second step, when the first step is continuously running, when too much debris is accumulated in the filter cartridge 6 corresponding to the injection pipe 10, the motor II 91 drives the driving gear II 95 to rotate, and synchronously drives the two driven gears II 96 to rotate, thereby driving the two screws 92 to rotate. The two screws 92 rotate in the same direction and the thread directions are opposite, so that the two moving blocks 93 move in opposite directions. The moving block 93 drives the holder 94 to move the injection pipe 10 from the filter cartridge 6 with accumulated debris to the filter cartridge 6 without accumulated debris. The filter cartridge 6 with accumulated debris is opened to discharge the debris into the debris chamber 3, and the filter cartridge 6 without accumulated debris continues to perform filtering and separation work. Therefore, the collection process after the debris is separated does not need to be stopped, thereby improving efficiency;

[0060] The third step is to pump the separated sewage out of the separation chamber 1 through the sewage suction pump 11, and transfer the sewage to the treatment chamber 2 through the transfer pipe 12. During this process, the volume and water quality of the sewage transferred to the treatment chamber 2 are monitored by the detector 13 and the flow meter 14 respectively, and the monitoring data is transmitted to the controller 4, and the controller 4 performs corresponding calculations according to the water quality and volume of the sewage;

[0061] In the fourth step, the controller 4 performs different execution modes according to the water quality and volume of the sewage, determines the total amount of chemical agents required according to the volume of the sewage, and controls several electric rotary valves 17 to open. The electric rotary valves 17 can accurately control the valve opening and the amount of materials added, so that the amount of inorganic flocculants, organic polymer flocculants, biological enzyme preparations, activated carbon powder and stabilizers is 40%, 20%, 15%, 10% and 5% of the total amount, and the required pH adjuster content is calculated according to the water quality of the sewage to ensure that the pH value is adjusted to an appropriate range. The amount of water added is determined according to the amount of the pH adjuster, so that the content of the pH adjuster and water accounts for 10% of the total amount of the required chemical agents, replacing the manual feeding method, the feeding ratio is accurate, and it is not easy to have a certain agent over- or under-feeding. The water quality is fully understood, and intelligent deployment is carried out in a targeted manner according to the actual situation of the sewage to ensure the sewage treatment effect;

[0062] The fifth step is carried out simultaneously with the third step. The debris separated in the second step is discharged from the filter cartridge 6, and the bucket conveyor belt 19 and the guide plate 20 are used to transfer the debris for subsequent treatment. The treatment of the debris and the sewage treatment do not affect each other, and there is no need to stop the machine for separate treatment.
