Treatment water reuse method Heavy metal wastewater treatment device

摘要

The present invention relates to a treatment water-containing heavy metal-containing wastewater treatment apparatus for treating wastewater containing heavy metal ions in which hydroxide precipitation is formed.;Conventional wastewater treatment processes for wastewater containing heavy metal ions are as follows: Feed wastewater-Screen-Equal tank-pH adjustment tank-Reactor-Coagulation tank-Settling tank-Treatment tank (neutralization tank)-Filter-Ion exchange resin tower--It is treated through discharge process.;Such a conventional apparatus is processed through various complicated processes, and the operation is complicated and requires a large area.;The present invention comprises a cone-type supply fluid tank, a tubular fine filter having a feed water pump and a tubular filtration membrane, and an electrodialyzer to form an intermediate-sized sediment in the supply fluid tank by an injection medicine, And the wastewater is filtered by a cross flow filtration method in a tubular fine filter, and the filtered water is passed through an electro-dialyzer to collect trace amounts of heavy metals and some ion components And can be recycled. By simplifying the construction, it is very easy to operate and the required area can be minimized. However, since the treatment efficiency is higher than that of the conventional device, the discharged water quality can be dramatically improved, Waste water treatment system containing heavy metals.
