A kind of chassis type long fiber filter and its construction method

Abstract

Disclosed are an underframe type macrofiber filter pool and a construction method thereof. The underframe type macrofiber filter pool comprises macrofiber filtering modules and a pool body with internal bottom beams. A grid type underframe is fixed onto the bottom beams; the inside of every grid of the grid type underframe is provided with a corresponding filter plate module and a corresponding macrofiber filtering module, wherein the macrofiber filtering module is arranged above the filter plate module. The construction method of the underframe type macrofiber filter pool comprises constructing the pool body and mounting a maintaining channel, setting a sealing door between the pool body and the maintaining channel, building the horizontal bottom beams inside the pool body, and then connecting the grid type underframe to the bottom beams; mounting and fastening the macrofiber filtering modules on every grid and connecting the bottom of every macrofiber filtering module and the grid type underframe together from the bottom of the grid type underframe; mounting and fastening the filter plate modules separately onto every grid, mounting the leveled filter plate modules under the macrofiber filtering modules from the bottom of the grid type underframe, and fixing the filter plate module to the grid type underframe.

Description

technical field [0001] The invention relates to a bottom-frame long-fiber filter tank and a construction method thereof, which is mainly used for water supply treatment and advanced treatment of sewage (waste) water, and belongs to the technical field of water supply and sewage (waste) water treatment. Background technique [0002] Filtration is one of the most commonly used and effective means to remove suspended solids (turbidity) and related substances in water treatment. Since the construction of the world's first slow filter by London Chelsea Water Supply Company in 1829, the filter has experienced the evolution process from slow filter to fast filter, from single-layer filter material, double-layer filter material to multi-layer filter material . During this period, most of the filter materials of the filter are quartz sand, anthracite, activated carbon, magnetite, ceramics, plastic balls and other granular materials with different particle sizes and different specifi...

AI Technical Summary

Problems solved by technology

[0007] However, a group of large municipal filters are usually within tens of m 2 , it must be arranged by dozens of components. After dozens of components are assembled to form a whole, the uniformity of the distribution of the filter material on the horizontal plane cannot be guaranteed, and even the uniformity of the distribution of the filter material on the horizontal plane will be destroyed.
