Description

Sludge self-discharging glass fiber reinforced plastic sedimentation tank

Technical Field

The utility model belongs to the technical field of sedimentation tanks, and particularly relates to a glass fiber reinforced plastic sedimentation tank capable of automatically discharging sludge.

Background

The sedimentation tank is the most commonly applied dispersed sewage treatment technology, has the advantages of simple structure, convenient management, low cost and the like, can be used as a temporary or simple drainage facility and also can be used as a pretreatment facility in a modern sewage treatment system, and plays a positive role in sanitation epidemic prevention, pollutant degradation, interception of large-particle substances in sewage and prevention of pipeline blockage. At present, in China, almost every city building is provided with a sedimentation tank, and a village dispersion household provided with a water flushing toilet is also provided with a sedimentation tank. With the popularization of urban centralized sewage treatment plants, many foreign countries gradually cancel the setting of sedimentation tanks, but the sedimentation tanks still play an important role in rural dispersed sewage treatment.

The sedimentation tank is used as a pretreatment facility of domestic sewage, and utilizes anaerobic fermentation and standing separation principles. Under the action of gravity, large-particle substances in domestic sewage subside (form sediment) or float upwards (form scum), and organic matters are partially degraded through anaerobic fermentation, so that the preliminary treatment of sewage is realized, the simple drainage requirement is met, or the subsequent drainage and sewage treatment are facilitated. The sewage is gradually separated into 3 layers of a floating slag layer, an intermediate layer and a sediment layer in the sedimentation tank. The light-specific-gravity substances (oils) or the flocks with bubbles are suspended upwards to form a slag layer, and the solid with high specific gravity is deposited on the bottom layer. Under the action of facultative/anaerobic bacteria, pollutants in sewage are decomposed to generate gases such as CH4, C02, H2S and the like. After full stabilization, the clear solids can be used as fertilizer, and the liquid in the middle layer can be directly discharged when the environmental requirement is not high, otherwise, the liquid needs to enter a subsequent processing unit for further processing. The bottom sediment needs to be cleaned out regularly so as not to influence the treatment effect of the sedimentation tank.

The existing buried equipment is usually only provided with a simple lifting pump and a pipeline for single-point sludge discharge, and the mode can not well discharge the sludge at the bottom of the tank body for the tank body structure with a longer axial length, so that the sludge accumulation at the bottom part of the tank body can not be discharged after long-time use, and the normal treatment of sewage in the tank body is affected.
