Embodiment Construction

[0012] Below in conjunction with an embodiment the present invention will be further described (see Figure 1-Figure 2 shown):

[0013] The system is mainly composed of a sewage sedimentation tank 1, a flocculant stirring tank 2, a coagulation reactor 3, and a belt filter press 4. The system is mainly divided into the following sections according to the sewage treatment process:

[0014] 1. Chemical pretreatment dehydration section:

[0015] In order to improve the dehydration of sewage, improve the properties of filter cake, and increase the permeability of materials, chemical treatment of sewage is required. First, the sewage is deposited in the sewage sedimentation tank 1, and flocculant is added in the flocculant mixing tank 2, and the sewage The sedimentation tank 1 and the flocculant stirring tank 2 are respectively connected to the coagulation reactor 3 through pipelines. The coagulation reactor 3 can achieve the effect of chemical dosing and flocculation. This design...

Abstract

The invention relates to an aluminium alloy anodized waste water belt type press filteration system. The system mainly comprises a sewage sedimentation tank, a flocculant stirring tank, a coagulation reactor and a belt type pressure filter, wherein the sewage sedimentation tank and the flocculant stirring tank are respectively connected with the coagulation reactor by a pipeline; the coagulation reactor guides the mixed liquid therein into a blanking hopper positioned on the belt type pressure filter by the pipeline. Compared with the prior art, the aluminium alloy anodized waste water belt type press filteration system has the following advantages of continuous production, stable performance, low maintenance rate, strong corrosion resistance, low energy and drug consumption, large treatment capacity, low water content of filter cakes, easy operation, easy maintenance and easy cleaning and the like. The aluminium alloy anodized waste water belt type press filteration system really solves the actual problems that the dehydration treatment of industrial acid-base neutralization waste residue has high energy consumption and low slag-pressing efficiency, thus being ideal equipment for saving energy, protecting environment, treating sewage, improving production efficiency and reducing labor intensity.

Description

Technical field: [0001] The invention relates to the technical field of sewage treatment, in particular to a belt filter press system for aluminum alloy anodic oxidation wastewater. Background technique: [0002] At present, according to the national environmental protection requirements, the aluminum industry needs to treat the sewage discharged every day before it can be discharged, and most enterprises use traditional hydraulic box filter presses to treat sewage. This kind of hydraulic box filter press has a large power, a single unit can reach 20kw, and the sewage treatment is only 4 cubic meters per hour. It consumes a lot of energy, but the processing efficiency is very low. Aiming at the common problems of this type of products and the characteristics and requirements of domestic acid-base neutralization and waste slag dehydration, it is an urgent task for the aluminum industry to design a system specifically for the treatment of aluminum alloy anodic oxidation waste...
