Industrial wastewater biological membrane multi-stage treatment device

Abstract

The invention discloses an industrial wastewater biological membrane multi-stage treatment device which structurally comprises a water outlet tube, a control panel, a purification medicine holding cabin, a water inlet tube, a biological membrane treatment water cabin and a multi-stage purification water cabin, wherein the water outlet tube is mounted on the left side of the multi-stage purification water cabin and is welded with the multi-stage purification water cabin; the multi-stage purification water cabin is a rectangle; the control panel is arranged above the right part of the front sideof the multi-stage purification water cabin; the multi-stage purification water cabin is buckled with the control panel; the biological membrane treatment water cabin is arranged on the right side ofthe multi-stage purification water cabin; the multi-stage purification water cabin is locked with the biological membrane treatment water cabin; the biological membrane treatment water cabin is mounted below the purification medicine holding cabin and is in clearance fit with the purification medicine holding cabin; the biological membrane treatment water cabin is a rectangle. When the equipmentis used, through a medicine control mechanism, the problems that purification medicines can be mixed in advance when being not stored independently, and medicines are not completely purified since theholding ratios are not precise, can be avoided, and the equipment can be relatively reasonable in medicine control and relatively complete in purification.

Description

technical field [0001] The invention relates to a biofilm multistage treatment device for industrial waste water, which belongs to the field of multistage treatment equipment for industrial waste water. Background technique [0002] The biofilm method is to make microorganisms attach to the surface of the carrier. During the process of sewage flowing through the surface of the carrier, the adsorption of organic nutrients, the diffusion of oxygen into the interior of the biofilm, and the biological oxidation that occurs in the film will remove pollutants. In the biofilm reactor, pollutants, dissolved oxygen and various necessary nutrients must first diffuse to the surface of the biofilm through the liquid phase, and then to the interior of the biofilm. Only the pollutants that diffuse to the surface or inside of the biofilm can There is an opportunity to be decomposed and transformed by biofilm microorganisms. As time goes on, the distribution of biofilm along the direction o...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a multi-stage biofilm treatment device for industrial wastewater to solve the problem that when used in the prior art, the purification agent treatment is easy to be mixed in advance because there is no separate storage, and the placement ratio is not high. Accurate, leading to the problem of impure purification agent and incomplete reaction purification
