Description

TECHNICAL FIELD

[0002] With the gradual development and improvement of urbanization in China, sewage treatment facilities are increasingly improved, and the demand for sludge treatment is also gradually increasing. In order to improve the efficiency of sludge treatment and increase the resource utilization of sludge, ultrasonic, digestion, electric field and oxidation treatment technologies have been widely applied. However, there is a common problem of insufficient carbon source and C / N value imbalance in the currently operated sewage plants in China, which affects the efficiency of nitrogen and phosphorus removal. In order to ensure the efficiency of nitrogen and phosphorus removal, it is a common way to use the residual sludge in the sewage treatment process to supplement the carbon source, that is, to destroy the microbial cells in the sludge and dissolve the organic carbon source in the content. This treatment method not only increases the carbon source of the influent, which is beneficial to the anaerobic digestion reaction of microorganisms, but also effectively solves the disposal dilemma of large amount of residual sludge and significantly reduces the pressure of sludge treatment.
