Mud harmless treatment device and mud treatment method

Abstract

The invention discloses a mud harmless treatment device and a mud treatment method. The mud harmless treatment device comprises a mud collecting tank, mud distributors, a reaction pipeline, a first mud supply device, diluting barrels, a dosing tube, a laminated spiral pressure filtering device, settling tanks and a conveyer belt, wherein the reaction pipeline is communicated with each of the mud distributors; the first mud supply device conveys mud in the mud collecting tank to the reaction pipeline; the diluting barrels are used for diluting a flocculating agent; the dosing tube is communicated with each of the diluting barrels and the first mud supply device; a dosing valve is arranged on the dosing tube; the laminated spiral pressure filtering device comprises a mud inlet, liquid outlets and a mud outlet; the mud inlet of the laminated spiral pressure filtering device is communicated with each of the mud distributors; the settling tanks are used for treating materials from the liquid outlets of the laminated spiral pressure filtering device; the conveyer belt is arranged below the mud outlet of the laminated spiral pressure filtering device. According to the mud harmless treatment device and the mud treatment method, unified collection and centralized harmless treatment of mud are realized, cyclic utilization of resources is realized, and environmental protection, energy conservation and zero emission are also truly realized.

Description

technical field [0001] The invention belongs to the technical field of construction sludge treatment, and in particular relates to a mud harmless treatment device and a mud harmless treatment method. Background technique [0002] With the continuous acceleration of economic development and urbanization, the construction of various projects in our country is in the ascendant. A large amount of construction mud is produced in the construction process of pile foundation engineering, underground tunnel shield engineering, and foundation pit support, with an annual output of hundreds of millions of cubic meters. Construction mud is mainly mud water containing silt, in which silt is suspended in the water, and the natural sedimentation efficiency is very low, and direct discharge will cause serious pollution to the water body. [0003] At present, the commonly used methods for mud purification in the industry are: (1) Natural sedimentation: digging pits, dams, collecting on-site ...

AI Technical Summary

Problems solved by technology

[0005] The first purpose of the present invention is to provide a mud harmless treatment device to solve the problems of illegal discharge or centralized stacking of construction mud in the process of transporting construction mud, which takes up a large area and has low sedimentation efficiency and long period.
