Description

Sludge dewatering device for river regulation

Technical Field

The utility model belongs to the technical field of the river course is administered, especially, relate to a sludge dewatering device is used in river course is administered.

Background

With the development of socio-economic and the acceleration of urban processes, the amount of sewage and sludge in cities and towns, enterprises and the like is rapidly increased. Because the existing sludge treatment equipment has high price and higher operation cost, a plurality of sewage treatment plants often only treat sewage and bury the sludge, thereby causing serious environmental pollution. The sludge contains a large amount of water, the water content is generally ninety-seven percent to ninety-nine percent, and before the sludge is treated, the sludge is usually required to be dehydrated to reduce the water content of the sludge, so that the resources can be utilized to the maximum.

The existing sludge dewatering comprises the following methods: 1. a natural drying method: mainly depends on evaporation, and can be reduced to about seventy-five percent after a plurality of weeks. The dehydration effect of the sludge drying bed is influenced by local rainfall, evaporation capacity, air temperature, humidity and the like. Is generally suitable for being adopted in dry, rain-less and sandy soil areas; 2. a granulation dehydration method: an underwater granulating dehydrator is a new device developed. The main body is a horizontal cylinder made of steel plate, which is divided into a granulating part, a dewatering part and a compacting part, and slowly rotates around a horizontal shaft. The sludge added with the macromolecular coagulant enters a granulation part firstly, is subjected to flocculation compression under the action of the self gravity of the sludge, is rolled into sludge balls in a layering way, then the sludge balls and water enter a dewatering part, and the water is discharged from an annular water discharge inclined seam. Finally, the mud pills enter a compacting part, and are further compressed and dehydrated under the dead weight to form mud pills with large and compact particles, and the mud pills are pushed out of the barrel body. The granulator has simple structure, low power consumption and easy maintenance, and is not easy to wear. The water content of the mud pills is generally about seventy percent. The filtrate produced in the sludge dewatering process in sewage plants contains high concentrations of pollutants, except for a relatively low content of filtrate pollutants in the drying bed. These filtrates must therefore be treated, generally with influent wastewater; 3. mechanical dehydration method: generally, sludge is pretreated first, and then dewatered after the dewatering performance is improved. The most common pretreatment method is the addition of inorganic salts or polymeric coagulants. In addition, there are elutriation methods and heat treatment methods. Mechanical dewatering methods include filtration and centrifugation. The filtration is to filter the wet sludge with a filtration layer (porous material such as filter cloth, wire mesh) so that water (filtrate) permeates the filtration layer and the dewatered sludge (filter cake) is retained on the filtration layer. The centrifugal method is to separate mud from water by means of different centrifugal tendencies generated by the specific gravity difference between solid and liquid in sludge. The filtration method uses equipment such as vacuum filter, plate-and-frame filter press and belt filter.

In summary, the problems of the prior art are as follows: in the prior art, mechanical dehydration equipment has a complex structure and low dehydration efficiency, and the mechanical dehydration pretreatment is carried out by adopting methods such as biological decomposition, heat treatment and the like, so that the operation cost is high, the investment is large, and the energy is consumed.
