Abstract

The invention discloses an ultrasonic treatment device and an ultrasonic treatment method for polymer-containing sludge. The device comprises a homogenization tank, an ultrasonic reaction tank and a flocculating and settling tank which are communicated mutually through pipelines. An ultrasonic probe is arranged in the ultrasonic reaction tank, and is connected with an ultrasonic generator. A stirrer is arranged in the flocculating and settling tank. The upper portion of the flocculating and settling tank is communicated with a chemical dosing device. The ultrasonic treatment device and the ultrasonic treatment method have the advantages that through the sponge effect and the cavitation effect of ultrasonic waves on the polymer-containing sludge, the viscosity of the polymer-containing sludge can be reduced without addition of viscosity reducers, and the dewatering capability of the polymer-containing sludge is improved; the polymer-containing sludge is treated, the feeding quantity ofchemicals is reduced, the yield of the sludge is decreased, the treatment efficiency of the polymer-containing sludge is improved, and the foundation is laid for harmless treatment of the polymer-containing sludge.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to an ultrasonic treatment device and method for sludge containing aggregates. Background technique [0002] Aggregated sludge, that is, sludge containing a large amount of polymers and crude oil. Due to the residual polymer in the sludge, it is more viscous, easy to form agglomerates, more complex in composition, higher in emulsification degree, difficult to completely settle the solid phase, and more difficult to handle. At present, the general treatment methods for aggregate-containing sludge mainly include conditioning-mechanical separation, pyrolysis, coking, chemical heat washing, solvent extraction, biological treatment, microwave method, electrochemical method, etc., without exception, these methods Pros and cons. Among many methods, none of them can truly realize the complete and harmless treatment of sludge containing aggregates, and many methods are still in the laborato...
