Filtering device for treating aquaculture tail water

Abstract

The invention discloses a filtering device for treating aquaculture tail water, which comprises a plurality of groups of symmetrically arranged concrete prefabricated columns, inter-column connecting rods are symmetrically fixed between each group of concrete prefabricated columns through fixing assemblies, and a partition plate is arranged between every two adjacent inter-column connecting rods; the inter-column grating plates are arranged between every two adjacent groups of concrete prefabricated columns through limiting assemblies; the supporting assembly is fixed to the bottom end of the concrete prefabricated column; the invention relates to the technical field of aquaculture tail water treatment. The whole structure of the filtering device is assembled in a modularized mode, rapid arrangement is facilitated, the number of modules can be flexibly increased or decreased according to the water treatment amount, and particularly, the filtering device can be rapidly assembled in an area where drainage construction cannot be conducted and then put into use; the overall cost is lower than that of on-site masonry after large-scale prefabrication, the construction period is shorter than that of on-site masonry, and labor is less; due to the adoption of modular assembly, later disassembly and maintenance are facilitated, and particularly, when the filtering device is blocked, the filtering device can be quickly disassembled to prevent overflow.
