Abstract

The invention relates to an ultrasonic cavitation-plasma sludge harmless treatment device and method. The device comprises a reactor (6), a hopper (1) is arranged at the top of the reactor (6), a material feeding valve (3) is arranged between the hopper (1) and the reactor (6), a material discharge valve (7) is arranged at the bottom of the reactor (6), a plasma generator (8) is arranged in the center of the reactor (6) through a support frame (9) and the inner wall of the reactor (6) is uniformly provided with multiple ultrasonic cavitation devices (5). The ultrasonic cavitation-plasma sludge harmless treatment device and method have the characteristics of high efficiency, cleanness, convenience and economy. The device utilizes ultrasonic cavitation and plasma for sludge treatment, is free of other auxiliary materials and additives, has good inclusiveness, realizes thorough disinfection and has strong functions of mildew and stinking smell removal. The treatment device and method realize sludge treatment, do not produce any residues and prevent secondary pollution.

Description

technical field [0001] The invention relates to an ultrasonic cavitation plasma sludge harmless device and method, which is especially suitable for sludge produced by domestic sewage and the like. Background technique [0002] With the continuous development of society and economy and the acceleration of urbanization, the amount of sewage treatment is increasing day by day, and the large amount of sludge produced in the process of sewage treatment has become a heavy burden for sewage treatment plants. [0003] The existing sludge disposal methods mainly include fertilizer making, landfill and incineration. Fertilizer pollutes the soil, causing widespread public nuisance, and its use has been restricted or banned in different countries. Landfill will occupy a large amount of land, and improper anti-seepage will lead to extensive pollution of soil and groundwater. Currently, the amount of sludge incinerated is increasing substantially. Incineration can kill pathogens and mi...
