Embodiment

[0027] like figure 1 As shown, the sludge freeze-thaw dehydration treatment system includes a freezing chamber for cooling the sludge and a melting chamber connected with the freezing chamber and used for heating the sludge. The freezing chamber is provided with an evaporator for cooling the sludge. The melting chamber is also provided with a hot water pipe for heating the sludge, and the freezing chamber and the melting chamber are also equipped with a conveyor belt for transporting the sludge, and the conveyor belt extends to the freezing chamber and the melting chamber, and the conveyor belt is located in the Below the evaporator and hot water pipes. In order to facilitate better heating of the frozen sludge, the freezer is also provided with a fan coil for blowing the heat released by the hot water pipe to the sludge, and the air outlet of the fan coil is located in the hot water above the tube.

[0028] In order to reduce costs and realize rational utilization of effect...

Abstract

The invention discloses a sludge freeze thawing dewatering treating system and a treating method using the system, solving the problems of poor sludge dewatering effect and higher cost in the prior art. The sludge freeze thawing dewatering system comprises a freezing chamber for freezing sludge and a thawing chamber communicated with the freezing chamber and used for heating the sludge, wherein an evaporator for cooling the sludge is arranged in the freezing chamber; a hot water pipe for heating the sludge is arranged in the thawing chamber; a conveyer belt for conveying the sludge is arranged in the freezing chamber and the thawing chamber and extends out of the thawing chamber; and the conveyor belt is arranged below the evaporator and the hot water pipe. The invention also provides a treating method using the sludge freeze thawing dewatering treating system. The sludge freeze thawing dewatering treating system is simple in structure, low in price, convenient for operation and excellent in sludge dewatering effect.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a sludge freeze-thaw dehydration treatment system and a treatment method thereof. Background technique [0002] With the rapid development of society, human beings are using more and more water resources, resulting in increasing sewage discharge. People are paying more and more attention to water environment protection. Many sewage treatment plants have been built and put into operation in major cities. The operation of a large number of sewage treatment facilities will effectively improve the water quality and environmental conditions, and the sludge produced with sewage treatment has become a new environmental problem. [0003] Sludge treatment methods mainly use concentration, stabilization, conditioning, dehydration, etc. Among many treatment methods, the primary problem is to solve the problem of sludge dehydration. Although the sludge has a hig...
