Description
(1) technical field
The present invention relates to field of waste water treatment, more particularly to a kind of wastewater treatment using jute powder adsorbing hexavalent chromium to fill
Put.
(2) background technology
Chromyl waste water is mainly derived from the productions such as metallurgy, intermetallic composite coating, plating, paint, printing and dyeing and chromate production
Industry, Cr VI can enter human body by food, and be enriched with vivo, and enrichment to a certain extent, can cause Itai-itai diseases, heredity base
Because of defect and cancer etc., thus Cr VI has been listed in one of 8 kinds of maximum chemical substances of harm to the human body, while is also state
One of 3 kinds of generally acknowledged carcinogenic metal objects of border, thus the Cr VI in waste water have to pass through processing it is up to standard after can discharge.
At present, the conventional processing method of Cr VI mainly has coagulant sedimentation, ion-exchange and electroosmose process in waste water
Deng.Coagulant sedimentation technical maturity, application time length, but treatment effeciency is low, and easily trigger secondary pollution；At ion-exchange
Positive effect, but complex process are managed, ion exchange resin price is high, causes cost height；Electroosmose process needs to consume big energy
And dialyser, cost are higher.
Jute be Tiliaceae Corchorus annual herb plant, be that quantity is enriched, it is cheap, wide material sources can be again
Production-goods source.The blade of long fruit jute and it is tender slightly on histocyte in rich in the polysaccharose substance such as pectin, these polysaccharose substances
In rich in-OH and-NH2Deng group, under certain pH, there is very strong chelation to Cr VI, be a kind of natural chela
Mixture.
However, the existing device that heavy metal in waste water is adsorbed using jute, if Jiang Ping is in Publication No.
A kind of water treatment facilities that heavy metal lead is adsorbed using tossa disclosed in CN203513320U, has automaticity
Low, labor intensity is big, can not continuous production, the processing time length shortcoming such as low with treatment effeciency, be not suitable for large-scale promotion application.
(3) content of the invention
In view of the shortcomings of the prior art, the present invention provides a kind of wastewater treatment equipment using jute powder adsorbing hexavalent chromium,
The device can utilize the Cr VI in cheap jute powder efficient absorption waste water, have simple in construction, automaticity height,
The advantages that treatment effeciency is high, continuous production, and investment is small and easy to use.
The technical scheme is that：
A kind of wastewater treatment equipment using jute powder adsorbing hexavalent chromium, it is characterised in that including adsorption tank, settling tank,
