Background Along with the acceleration of the urban process and the expansion of the sewage treatment scale, the sludge is used as a byproduct of sewage treatment, and the yield of the sludge is in a year-by-year surge state. Sludge is rich in pollutants such as organic matters, heavy metals, pathogens and the like, and secondary pollution is easy to cause if the sludge is improperly treated, so that sludge reduction treatment is one of the core research subjects in the field of environmental protection. Compared with ex-situ disposal modes such as sludge outward-moving incineration, landfill and the like, the sludge in-situ reduction technology has the advantages of small occupied area, low energy consumption, short flow and the like, and becomes the main flow direction of current industry development, and the core principle is that degradation and reduction of sludge are realized in a sewage treatment system through biological, chemical or physical means, so that the final disposal quantity is reduced. However, the conventional sludge in-situ reduction technology for replacing the traditional carbon source by using the biological enzyme still has the key technical bottlenecks that the biological enzyme and the sludge have poor mixing cooperativity and insufficient adding accuracy, so that the utilization rate of the enzyme is low, and the catalytic efficiency of the biological enzyme is difficult to fully develop. In addition, the enzyme preparation is fed by adopting a gravity feeding or fixed-rate pumping mode, and a dynamic matching mechanism with the concentration of the sludge and the reaction process is lacking, so that when the viscosity or the treatment capacity of the sludge fluctuates, the problems of waste caused by excessive enzyme feeding or poor decrement effect caused by insufficient feeding are easily caused.
