Chromium-containing wastewater treatment system using water column generation absorption principle

Abstract

The invention discloses a chromium-containing wastewater treatment system using a water column generation absorption principle. The chromium-containing wastewater treatment system structurally comprises water outlets, a filter tank, a water inlet, an observation opening, a portable handle, a sealing cover plate and a controller. Chromium matter in wastewater is treated in the filter tank through afilter wheel set, when the level of the wastewater is up to the position of a driving shaft, water pressure enters an expansion cylinder to drive a filter screen to extend, and then it is achieved that the filter density and range are automatically adjusted. A water diversion mechanism can detect the highest level of the wastewater through a floating block, and then wastewater discharges are intensively output; an adsorption water column formed by a contaminant-holding assembly can quickly absorb the chromium matter, precipitation is prevented, through overall cooperative use, it can be achieved that the filter wheel set is washed and dredged, the blocking situation is effectively avoided, the problem of coagulation on the bottom is solved, and the high-order wastewater filtration qualityis improved.

Description

technical field [0001] The invention relates to the field of industrial waste water treatment, in particular to a chromium-containing waste water treatment system adopting the principle of water column generation and absorption. Background technique [0002] In the industrial processing industry, chromium mining, smelting, chromium salt, electroplating and metal processing equipment will produce wastewater with a certain chromium content, and chromium is easy to adhere to other impurities in the wastewater, which is not easy to collect and affects other Therefore, there are special equipment for the treatment of chromium wastewater on the market. Otherwise, improper treatment will cause great harm to the environment and society. There are such problems in the use of existing technologies on the market: [0003] The processing device of the present technology has a poor effect on collecting chromium. Due to the volume expansion caused by its adhesion, it will quickly condens...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a chromium-containing wastewater treatment system using the principle of water column generation and absorption, so as to solve the problem that the treatment device in the prior art has a poor collection effect on chromium and the volume caused by its adhesion Expansion, after entering the processing equipment, it will quickly condense at the bottom, which is not conducive to high-level filtration, and the traditional filter collection method will directly lead to a reduction in the life of the filter and a large amount of clogging, which needs to be optimized.
