Water-distribution, gas-distribution and aeration multifunctional filter tube, multifunctional filter tube filter tank, and water treatment method

Abstract

The invention relates to a water-distribution, gas-distribution and aeration multifunctional filter tube, a multifunctional filter tube filter tank, and a water treatment method. The filter tube has astrip-shaped tubular structure and an arched cross section, the top of the filter tube is provided with a filter tube top gas distribution hole, two sides of the waist part of the filter tube are symmetrically provided with filter tube side gas distribution holes, and the bottom plate of the filter tube is provided with filter tube water distribution holes and a vertical tube insertion hole; anda position, corresponding to the filter tube top gas distribution hole, of the top outer wall of the filter tube is detachably connected with an aerator. The filter tube of the invention has strong versatility, can be used in a conventional filter tank not requiring aeration, and also can be used in a filter tank that requires aeration. The filter tube of the invention can be widely applied to various types of new filter tanks such as a V-shaped filter tank, a deep bed filter tank and a flap filter tank, and can also be used in various filter tank reconstruction projects to achieve the purposeof replacing two independent water treatment process systems, required for the aeration process, the water distribution process and the gas distribution process in a biological aerated filter tank, with one process system.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a water treatment device component and a water treatment method. Background technique [0002] The biological aerated filter realizes the oxidative degradation of organic matter through the aeration function in the water treatment process. This process can not only effectively remove some fine suspended particles and colloidal substances that cannot be removed by coagulation and sedimentation, but also efficiently remove COD, BOD, Harmful substances in water such as phosphorus, heavy metals, bacteria and viruses. Therefore, it is an indispensable process unit in tap water production pretreatment and sewage treatment engineering. [0003] In order to realize the water filtration, backwashing and aeration process, the traditional biological aerated filter uses a set of water distribution and gas distribution system for water filtration and backwashing operation plus an aeration syst...
