Sludge and water separation rapid infiltration device

Abstract

The invention discloses a sludge and water separation rapid infiltration device which comprises supporting frames for fixing, a water conveying pipe for water drainage and infiltration modules, wherein the infiltration modules comprise water discharging cavities, supporting blocks and an infiltration bodies; water-permeable through holes are formed in the surface layers of the water discharging cavities; the upper surfaces of the supporting blocks are hollow disks; the water discharging cavities are arranged above the disks; the disks are connected with short pipes; the infiltration bodies are located on the disks and distributed around the peripheries of the water discharging cavities; thick filter nets cover the peripheries of the infiltration bodies; infiltration layers are arranged inside the thick filter nets; the infiltration modules are connected to the water conveying pipe; upside-down sealing sleeves are arranged at the tops of the infiltration modules in a sleeving manner; the lower ends of the sealing sleeves are provided with openings, and the upper ends of the sealing sleeves are closed; ventilating pipes are arranged at the tops of the sealing sleeves; the ventilating pipes are communicated with the water discharging cavities and are connected to a vacuum pump. The infiltration modules in the device can be repeatedly used; furthermore, filter materials in different filter material layers cannot be interblended; the filter material layers are independently taken out for replacement, filter material supplementation or cleaning, so that the sludge and water separation rapid infiltration device is convenient to produce and install; vacuum is formed in a system, so that drainage of filtrate is accelerated.

Description

technical field [0001] The invention relates to a rapid percolation device for mud-water separation, in particular to a rapid percolation device for mud-water separation in a drying pond temporarily constructed by using earth dikes. Background technique [0002] At present, most of the domestic waste mud is still treated by natural sedimentation and drying technology. In the field construction project, it is far away from the centralized treatment drying pool and there is an open space available or leased. The construction party builds the natural drying pool for the waste mud. This drying pool is formed by embankment of soil on the construction site, and the mechanism is relatively simple. . Due to the slow natural dehydration of the mud, a large area of ​​drying pond is required, which increases the rent, and the drying speed is more affected by the weather. Speeding up the drying speed of the mud can reduce the area and rental time of the drying tank. [0003] In the e...

AI Technical Summary

Problems solved by technology

[0003] In the existing percolation system technology of the drying tank, a filter layer is arranged horizontally at the bottom of the drying tank. After the filter layer is blocked, the backwashing system at the bottom is used for flushing. However, in the temporarily constructed drying tank installed in the field, The backwashing system is too complicated and the effect is not good. When using machinery to dig out the dried mud, it is easy to damage the filter material layer by improper operation; moreover, when the drying tank needs to be moved, it is difficult to distinguish and collect various filter materials in the drying tank, and it is also difficult to It is difficult to reuse; some perforated drainage pipes used to collect water in the mud are arranged vertically or horizontally in the drying tank, and the perforated drainage pipes are easy to block, difficult to clear, and the water is turbid
