Description

Ultrasonic sewage treatment system with quality-based matching Technical Field The invention relates to the technical field of sewage treatment, in particular to a quality-matching ultrasonic sewage treatment system. Background In the field of treatment of industrial wastewater and domestic wastewater, the ultrasonic degradation technology is widely applied to advanced treatment of refractory wastewater due to the fact that organic pollutant molecules can be efficiently broken down and micro colloid particles can be decomposed. The core of the device is that cavitation effect is induced by ultrasonic wave, and the generated high-temperature and high-pressure environment can destroy the chemical structure of the pollutant, so as to realize degradation and removal of the pollutant. However, the existing ultrasonic sewage treatment technology has the common defect of 'non-quality treatment', namely light scum (such as grease and foam), heavy scum (such as silt and metal particles) and intermediate-phase sewage containing soluble pollutants are often mixed in sewage, when the mixed sewage is directly subjected to ultrasonic treatment, the light scum can shield an ultrasonic propagation path, the heavy scum is easy to wear an ultrasonic transducer and interfere with cavitation effect, so that ultrasonic energy is wasted on non-target pollutants in a large amount, the degradation efficiency of organic pollutants in the intermediate-phase sewage is reduced, and the problems of high treatment cost and quick equipment loss are also caused. In order to solve the problems, some technologies attempt to add pretreatment procedures, such as grid filtration and sedimentation in a sedimentation tank, before ultrasonic treatment, but such methods can only remove impurities with larger particle size, and cannot realize accurate classification of light phase, heavy phase and intermediate phase in sewage, and still cannot avoid interference of impurities on ultrasonic treatment. In addition, the prior art adopts a centrifugal separation device to pretreat sewage, but the separated intermediate-phase sewage is easy to cause uneven concentration distribution due to flow state disorder, the follow-up ultrasonic treatment is still forced to adopt one-knife power setting, accurate energy matching can not be realized according to sewage concentration difference, the problem of insufficient ultrasonic energy or excessive ultrasonic is caused, and the defects of low treatment efficiency and insufficient energy utilization rate still exist. Therefore, how to realize accurate classification of sewage through reasonable pretreatment and treatment flow design and to match different ultrasonic treatment schemes for sewage with different concentrations so as to improve ultrasonic degradation efficiency and reduce energy consumption becomes a key problem to be solved urgently in the technical field of current ultrasonic sewage treatment.
