A kind of sludge thickening and dehydration treatment method

Abstract

The invention discloses a sludge concentration and dewatering treatment method. The method comprises the following steps: (1) sludge pulverizing treatment; (2) sludge conditioning treatment; (3) sludge extrusion treatment; (4) sludge drying treatment; and (5) sludge storage. The method disclosed by the invention is simple in structure, high in practicality, convenient to use and remarkable in the sludge dewatering effect; through the multiple treatments of a pulverizing cavity, a conditioning tank and a dewatering cavity, void water, adsorbed water and capillary water in sludge are all separated out, so that the dewatering rate of the sludge is effectively improved, and the volume of the sludge is reduced, thereby facilitating subsequent recycling of the sludge; and the overall structure design is more reasonable and scientific.

Description

technical field

[0001] The invention relates to a sludge concentration and dehydration treatment method. Background technique

[0002] The process of urbanization in our country is in the stage of accelerating, and the situation of environmental pollution is also increasing. The sludge problem has become a major problem related to people's life. The annual sludge output in our country is very huge, and the weight is very alarming. At the same time, the total amount of sewage discharge in most cities is also in a trend of continuous and rapid increase. However, at the same time, the corresponding sewage treatment rate has not increased correspondingly, resulting in sludge discharge and stacking has become a new major pollution source. For the increasingly large amount of sludge, it has become the focus of our country's staff to take effective measures to dehydrate these huge amounts of sludge, so that it can achieve the goals of being environmentally friendly, reducing the a...
