In industrial wastewater treatment, filtration and coagulation sedimentation are currently the more commonly used suspension treatment processes. In industrial wastewater, some pollutants are difficult to precipitate naturally due to various reasons, so they float on the surface with some small suspended solids. For this, we can put a certain amount of coagulant or coagulant in the industry. In the sewage, the pollutants or fine suspended matter suspended on the water surface form floccules, and the pollutants and the larger suspended particles can be separated by the subsequent sedimentation tank, and these pollutants and the larger suspended particles are separated from the subsequent The bottom of the sedimentation tank is smoothly removed, and the clean water is discharged from the top of the subsequent sedimentation tank to achieve the desired sewage treatment effect. After the industrial wastewater is coagulated and precipitated, it is cooled by the cooling tower and then recycled. In treated industrial wastewater, the SS is usually less than 30 mg/L.
The treatment of industrial sewage suspended solids can also effectively carry out large suspended particles or some petroleum-based pollutants in industrial sewage through relevant physical methods such as grids, strainers, screens, and slanting screens. Interception, this has a very important significance for the subsequent treatment of industrial sewage.
When the grille chain is driven by the drive mechanism of the reducer, the mechanical grille decontamination machine rotates according to the working direction. At this time, the water in the water tank flows through the gingival grid gap, and the grille teeth intercept the solid debris in the water. And it is picked up by the moving molars, and after running up to the top with the chain of teeth, through the guiding of the sprocket and the curved rail, the relative movement between each set of molars is achieved, achieving self-cleaning purposes, resulting in Most of the solid debris falls due to its own gravity, and other debris adhering to the gap is washed under the action of the reverse cleaning brush and evenly falls into the belt conveyor. Since the sprocket chain is a closed slewing mechanism, it can work automatically and continuously to continuously remove suspended debris from the water.
