Abstract

The invention relates to the technical field of landfill leachate treatment, in particular to a powdered activated carbon adding device for landfill leachate tail water treatment. The device comprisesa sliding mounting base and a sliding rail, the sliding rail is vertically arranged along the tank wall of a neutralization flocculation tank, the sliding mounting seat in sliding fit is disposed onthe sliding rail, one side of the sliding mounting seat far from the sliding rail is equipped with an outer cylinder and an inner cylinder, the top of the outer cylinder is equipped with an inlet, thebottom of the outer cylinder is equipped with an outlet, the inner cylinder is located inside the outer cylinder, the inner cylinder is equipped with a long and straight through-hole along the lengthdirection of the cylinder body, and activated carbon is added into the inner cylinder through the inlet on the outer cylinder and the through-hole on the inner cylinder. The device provided by the invention solves the problem of troublesome replacement process of activated carbon during adding of powdered activated carbon into the neutralization flocculation tank, makes the activated carbon replacement process faster and more convenient, saves time, ensures continuous and efficient landfill leachate tail water treatment, and the treatment process is obviously optimized.

Description

technical field [0001] The invention relates to the technical field of landfill leachate treatment, in particular to a powdered activated carbon dosing device for landfill leachate tail water treatment. Background technique [0002] The existing landfill leachate treatment generally adopts the "biochemical treatment + membrane treatment + "Advanced Oxidation" process, the treated filtrate water meets the standard requirements and then discharged. [0003] Under the existing process, when the treatment of landfill leachate tail water is abnormal, it is necessary to add powdered activated carbon to the neutralization flocculation tank to absorb pollutants to ensure the stability of the effluent. However, because the process needs to be carried out continuously, activated carbon often needs to be recycled and replaced regularly. At present, activated carbon Recycling and replacement is troublesome. Therefore, a powdered activated carbon dosing device for landfill leachate tail...
