[0002] With the rapid development of industries such as medicine, chemicals and new materials, the amount of hazardous waste generated in the manufacturing process is increasing. These wastes contain organic matter, which, if not properly handled, will not only cause serious pollution to the environment, but also threaten human health. Therefore, developing an efficient and environmentally friendly method for the treatment of hazardous waste has become an urgent problem to be solved.

[0003] At present, the treatment methods for this type of hazardous waste mainly include physical, chemical and biological methods. The physical method mainly changes the physical state of the waste by separation, concentration and other means, but it cannot fundamentally reduce the amount of waste and the difficulty of treatment. The chemical method changes the chemical properties of the waste through chemical reactions, but new harmful substances may be produced during the treatment process, and the treatment cost is relatively high. In contrast, the biological method has the advantages of environmental protection, economy and high efficiency, and has become a hot research topic in recent years.

[0004] The biological method mainly uses the metabolism of microorganisms to degrade and transform organic matter in waste. However, due to the complex composition of waste generated by the pharmaceutical, chemical and new materials industries, the biological method has problems with the degradation of such wastes, such as the inability to control and adjust the degradation reaction environment temperature in real time, the difficulty in controlling the degradation and reaction conditions of such wastes, and the long fermentation degradation treatment time. Summary of the invention

[0005] In order to solve the problems in the above-mentioned prior art that the degradation reaction environment temperature cannot be controlled in real time, the degradation and reaction conditions of such wastes are difficult to control, and the fermentation degradation treatment time is long, the present invention proposes an industrial hazardous waste reduction treatment system and process to improve the above-mentioned problems.

The PID control unit is used to adjust the pH value, stirring speed, gas flow rate and fermentation reaction temperature of the system processing process according to the parameter values ​​obtained by the monitoring control module until the parameter values ​​are adjusted to reach the preset values, wherein the adjustment of the fermentation and degradation reaction temperature is realized based on an immune genetic algorithm; the balancing processing unit is used to dynamically assist the PID control unit to take measures to achieve that each parameter meets the preset value, including temperature fine-tuning and pH fine-tuning; Among them, the fermentation reaction module is paved with a steam coil on the inner wall, and is equipped with 4 stirring shafts inside, corresponding to the upper left, lower left, upper right and lower right positions respectively. The stirring shaft is designed as a hollow structure for steam to pass through. The control of the stirring shaft and steam is carried out through the PID control module. The PID control module controls the reaction environment temperature of the fermentation reaction module. The steam coil is connected to the heating and cooling device, and the heating and cooling device can automatically control the cold and heat through the PID control module. The weighing sensor can display the total weight of the fermentation reaction module in real time, and is used to monitor the reduction fermentation degradation situation and progress of the fermentation reaction module.

[0007] Furthermore, the specific bacterial species of the composite bacterial agent include thermophilic spore bacillus photosynthetic bacteria, Bacillus licheniformis, forest bacteria, photosynthetic bacteria, lactic acid bacteria, actinomycetes Alberta Thiobacillus, fungi and Aspergillus niger, among which the photosynthetic bacteria are Rhodopseudomonas, the lactic acid bacteria are Lactobacillus acidophilus, and the fungi are tropical Candida strains, among which the number of tropical Candida strains accounts for 55% and the number of Aspergillus niger accounts for 45%.

[0008] Furthermore, the fermentation degradation reaction temperature is regulated based on an immune genetic algorithm, and the specific process is as follows: M1: Parameter encoding, using immune genetic algorithm to optimize PID control parameters, converting PID control parameters into binary digital form, , and Encoded as immune genetic algorithm antibody, where , and There are three parameters for PID, namely the ratio ,integral and differential Three parameters; M2: Calculate the fitness function.

The fitness function is: J = ; M3: Update memory cells. The high fitness of antibody cells is retained through the memory function and assigned to the PID controller parameters. The individual fitness function value is calculated to determine the optimal fitness value of the population. If the searched optimal fitness value is less than the optimal fitness value in the immune network, the immune memory starts to search for the optimal value again and uses it as the optimal immune antibody. Otherwise, the calculated optimal fitness value is added to the antibody memory list. M4: Maintain diversity and use selection probability to adjust the diversity of the population.
