Abstract

The invention provides a novel combined underground water chromium remover which comprises a water inlet unit, a reduction reaction unit, a filtering and separating unit and a water outlet unit which are sequentially connected, wherein the water inlet unit is connected with the lower part of the reduction reaction unit; the filtering and separating unit comprises an initial separation unit, a manganese sand filter layer and a pebble layer which are sequentially connected; the initial separation unit is connected with the reduction reaction unit; and the pebble bed is connected with the water outlet unit. The device has the advantages of compact structure, small occupied area, flexible operation and wide application range, is convenient to use, can well ensure the total chromium removal effect in underground water and the integral effluent water quality, and has favorable popularization and application prospects.

Description

technical field [0001] The invention belongs to the field of water treatment equipment, in particular to a novel combined type groundwater chromium removal device. Background technique [0002] The problem of groundwater pollution is one of the hot issues of domestic concern, and the problem of chromium pollution has attracted people's attention. The current "Drinking Water Hygiene Standard" (GB5749-2006) stipulates that the chromium content in drinking water should be less than 0.05mg / L. [0003] At present, scholars at home and abroad have carried out some studies on the removal of chromium from drinking water, and a chromium removal technology with ferrous sulfate as the main removal agent has also appeared, and certain removal effects have been achieved. However, since the chemical reaction that occurs during the removal of chromium is different from the general water treatment reaction, the removal efficiency of chromium by using the existing water treatment device is ...
