Belt type pressure filtration concentrated dewatering system capable of efficient dewatering

Abstract

The invention relates to a belt type pressure filtration concentrated dewatering system capable of efficient dewatering. The belt type pressure filtration concentrated dewatering system comprises a feeding device, a stirring and precipitating device, a filter belt conveying device, a water accumulation pond, a leveling component, an extrusion dewatering component and a discharging component; the discharging end of the feeding device is connected with the feeding end of the stirring and precipitating device; the stirring and precipitating device is used for fully stirring sludge and a flocculating medicament added inside the stirring and precipitating device; the filter belt conveying device is arranged under the sludge discharging end of the stirring and precipitating device; the sewage discharging end of the stirring and precipitating device is connected with the water inlet end of the water accumulation pond; the water accumulation pond is arranged under the filter belt conveying device; and the leveling component, the extrusion dewatering component and the discharging component are arranged on the filter belt conveying device and sequentially distributed in the conveying direction of the filter belt conveying device. The dewatering system provided by the invention can efficiently dewater the sludge, is simple to operate and convenient to use, and fully meets the demands on sludge dewatering and landfill.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a high-efficiency dehydration belt filter press concentration dehydration system. Background technique [0002] Sludge refers to the solid sediment produced in the process of water and sewage treatment; with the improvement of people's awareness of environmental protection, people's efforts to treat sewage are also increasing year by year, and the amount of sludge produced in the process of sewage treatment has also increased sharply If a large amount of sludge is not properly treated, it will cause secondary pollution; when treating sludge, it is often disposed of in the natural environment (ground, underground, water) or reused, which can achieve long-term stability and The final consumption method with no adverse effects on the ecological environment; the sludge obtained from sewage treatment contains a large amount of water, and the sewage needs to be dehydra...

[0002] Sludge refers to the solid sediment produced in the process of water and sewage treatment; with the improvement of people's awareness of environmental protection, people's efforts to treat sewage are also increasing year by year, and the amount of sludge produced in the process of sewage treatment has also increased sharply If a large amount of sludge is not properly treated, it will cause secondary pollution; when treating sludge, it is often disposed of in the natural environment (ground, underground, water) or reused, which can achieve long-term stability and The final consumption method with no adverse effects on the ecological environment; the sludge obtained from sewage treatment contains a large amount of water, and the sewage needs to be dehydrated before it can meet the requirements of landfill; often people simply pile up the sludge obtained from sewage treatment. The purpose of reducing the water content of sewage is achieved through water evaporation; however, relying on natural evaporation of water in the sludge is inefficient and time-consuming, and if it is in winter, the sludge cannot be dehydrated by evaporation; and the natural pile of sludge occupies a large area and is easy to cause pollution
