Embodiment Construction

[0020] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 As shown, the present invention is a sewage biological treatment filter box, which includes a box body 1 with an open top, and the material of the box body 1 is glass fiber reinforced plastic or steel.

[0022] A plurality of upright columns 2 are fixed inside the box body 1, and the upright columns 2 and the box body 1 are fixed together. The upright columns 2 are connected by multi-layer beams 3 , and grid plates 4 are fixed on each layer of beams 3 . With this structure, the filter tank and stuffing box are combined into one.

[0023] A water distributor 8 is arranged above the box body 1, and the water distributor 8 drips and filters the sewage from top to bottom, and the water droplets fully contact ...

Abstract

The invention relates to a biological sewage treatment filter box which comprises a box body with an opening in the top. Multiple layers of horizontally-arranged grid plates are mixed in the box body. Every two adjacent layers of grid plates are filled with light filling. A ventilating duct which vertically penetrates through the multiple layers of grid plates is arranged in the box body. A back flushing device is arranged below the lowest layer of grid plate, a water distributor is arranged above the box body, and the water distributor is communicated with the bottom of the box body through a pipeline and a circulation pump. According to the biological sewage treatment filter box, the grid plates and the box body are fixed together, a filter pool and a filling box are integrated, and anti-buoyancy back flushing can be achieved; due to the fact that the special ventilating duct is arranged, natural oxygen supply can be achieved, and the oxygen supply amount can be increased.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage biological treatment filter box. Background technique [0002] A biological filter is a device that uses biochemical methods for sewage treatment. Layered biological trickling filter is a kind of biological filter. [0003] In the prior art, a common structure of a biological filter includes a reaction tank and a stuffing basket, and the stuffing basket is filled with fillers and stacked in layers in the reaction tank. The oxygen supply of this biological filter is insufficient, which affects the treatment effect; when the packing layer is clogged, the blockage cannot be solved by backwashing, and the packing basket can only be taken out manually, cleaned or replaced, which greatly increases the labor cost. Contents of the invention [0004] The invention aims at the problems of insufficient oxygen supply and inability to backwash in the existing stratified ...
