Description
Technical Field
The invention belongs to the technical field of environment-friendly equipment, and particularly relates to a low-pressure high-frequency sludge wall breaking and dewatering device.
Background
With the continuous development of urbanization, the industrial and living standards are continuously improved, the demand consumption of people for production and living is continuously increased, and the amount of industrial wastewater and domestic sewage generated is increased, so that the output of residual sludge in the sewage treatment process is continuously increased, and a large amount of residual sludge needs to be discharged by a treatment plant. Meanwhile, with the improvement of the quality of social life, the requirements of people on the environment are higher and higher, so that the sludge needs to be further and reasonably treated, secondary pollution is avoided, however, the water content of the residual sludge is higher, the high water content causes high operation cost for subsequent treatment and treatment of the sludge, and the cost input is increased. The traditional mechanical dehydration method can dehydrate the sludge to 80% at most, and the physical method and the chemical dosing method are combined technically to remove the water content higher. However, the addition of chemicals not only imposes a burden on the natural environment, but also restricts the range of utilization of the sludge after dehydration.
At present, the treatment and disposal modes of the excess sludge after sewage treatment are generally landfill, land improvement, incineration or building material utilization and the like. These methods have certain requirements on the water content of the excess sludge. In order to avoid secondary soil pollution and possible water pollution, the water content of the sludge is required to be less than 60% in landfill, and in the process of preparing the building materials by burning, the water content of the sludge is required to be reduced to be less than 60% in order to reduce the consumption of auxiliary fuel, but because the particles of the residual sludge are fine and are in a micelle shape, the water can be bound in the micelle, so that the water is difficult to remove by adopting a conventional method.
The sludge is directly dried by heating with a heat source or electric energy, and the energy consumption is large. Although the cold plasma is generated with active particles through bombardment and dehydration by wall breaking through degradation reaction, the plasma under the atmospheric pressure needs high-voltage discharge to be generated in a large amount, generally, the method is only limited to organic pollution long-term soil remediation with the water content of less than 10 percent, because the water content of the residual sludge is higher and the conductivity is larger, if the high-voltage discharge mode electrode is in direct contact with the sludge, the electrode short circuit can be caused, the plasma discharge is difficult to generate, therefore, the electrode non-contact treatment is necessary, meanwhile, the flatness of the surface of the sludge is needed to be higher, the discharge particle effect only relates to the outer surface of the sludge, the wall breaking effect inside the sludge can not be realized, the wall breaking efficiency is lower, and the method is not beneficial to large-scale application.
Therefore, the method which is higher and more environment-friendly is adopted to break the outer walls of various micelles, cells and the like in the sludge, separate the water locked inside, improve the dehydration rate of the sludge, promote the subsequent advanced treatment, solve the treatment problem of the sludge, reduce the operation cost of sewage treatment, protect the environment, recover resources and energy and have great social, environmental and economic benefits.
