Industrial wastewater treatment system

Abstract

The invention discloses an industrial wastewater treatment system comprising a wastewater storage groove (1), a corrosion resisting water pump (3), a filtering column (4), a first exchanging column (2) and a second exchanging column (7), which are connected in sequence according to a treatment flow, wherein the filtering column (4) is filled with resin white ball filtering mediums (8); the first exchanging column (2) and the second exchanging column (7) are internally provided with ion exchange resin filtering devices (9); and water inlets of the first exchanging column (2) and the second exchanging column (7) are connected with a regenerated liquid groove (5) through a combined valve pipeline (6). According to the industrial wastewater treatment system disclosed by the invention, opposite ions on active genes of ion exchange resin and same ions in a solution are subjected to position displacement, and heavy metals including chromium, copper, cadmium, zinc, gold, silver, palladium, platinum, rhodium, nickel and the like in electroplating wastewater and substances with greater toxin can be treated; and resin can be repeatedly used so that a lot of cost is saved.

Description

technical field [0001] The invention designs wastewater treatment equipment, more specifically, it is a kind of industrial wastewater treatment equipment for treating heavy metal ions. Background technique [0002] Now my country's industry is developing rapidly, but at the same time of industrial modernization, it also causes serious environmental pollution, such as industrial waste gas and waste water pollution. Therefore, the treatment of industrial waste water has become very important. However, industrial wastewater, especially electroplating wastewater, has complex water quality and difficult to control components. It contains heavy metals such as chromium, copper, cadmium, zinc, gold, silver, palladium, platinum, rhodium, nickel, and cyanide, which are highly toxic, and some are carcinogenic. , teratogenic, mutagenic highly toxic substances, if discharged directly, will be extremely harmful to humans. However, some of the current wastewater treatment equipment cann...

Problems solved by technology

However, industrial wastewater, especially electroplating wastewater, has complex water quality and difficult to control components. It contains heavy metals such as chromium, copper, cadmium, zinc, gold, silver, palladium, platinum, rhodium, nickel, and cyanide, which are highly toxic, and some are carcinogenic. , teratogenic, and mutagenic highly toxic substances, if discharged directly, will be extremely harmful to humans

However, some of the current wastewater treatment equipment cannot effectively deal with all the above-mentioned harmful substances. Therefore, the treatment of this hazardous industrial wastewater has become an important and urgent issue to be solved.
