Abstract
The invention relates to a nano flocculating agent, which is suitable for flocculation, organic substance oxidation, inorganic substance agglomeration and complexing in water cleaning treatment, has a high comprehensive performance, and does not generate secondary pollution, and especially relates to an inorganic nano flocculating agent namely metal ions loaded attapulgite and a preparation method thereof. The inorganic nano flocculating agent is prepared by mixing attapulgite with a mixed solution containing aluminum, titanium, lanthanum, and cerium and then drying the attapulgite. The provided inorganic nano flocculating agent can flocculate inorganic pollutants and organic pollutants in water, then the precipitates are separated from water, catalytic oxidation reactions carry out in the presence of the catalyst namely metal ions loaded on attapulgite, the pollutants in the precipitates are decomposed through oxidation, and thus the transfer of pollutant source is avoided.
Description
Technical field
The present invention relates to a kind of be applicable to water cleaning process flocculation, oxidation operation, the high-performance of inorganics reunion complexing, the nano flocculant of non-secondary pollution, particularly relate to the inorganic nano flocculation agent of attapulgite loaded metal ion.
Background technology
Along with the development of society; can produce a large amount of containing organic waste water in the life process of people; these waste water are as unprocessed and direct discharge can cause very serious harm to environment, and the improvement of organic waste water has become a Current Domestic external environment resist technology field difficult problem to be solved for this reason.
Flocculation agent is must an obligato important step in existing water technology.Because its consumption is big, various countries scientific worker develops the numerous organic and inorganic polymeric flocculant of item in succession, and these polymeric flocculants common feature is by pollutent concentrating and precipitating organic and inorganic in water body, reach the object of clean water body.Be deposited concentrated pollutent then to transfer in throw out, with sedimental dehydration, outward transport and shifting.
At present, obtain certain achievement about in purification of waste water process both at home and abroad, the removal of the indexs such as turbidity, colourity, COD is had a significant effect, but still have certain limitation in NITROGEN IN LOW CONCENTRATION phosphorus content in reduction water body.Thus, probe into a kind of novel inorganic polymer flocculant, be suitable in the water body of low-temperature and low turbidity, reduce TN, TP content, in water conditioning, there is actual application value.
Summary of the invention
The object of the invention is to: for the technical deficiency of NITROGEN IN LOW CONCENTRATION phosphorus efficiency clearance in municipal effluent, provide a kind of with the attapulgite clay of high-specific surface area for carrier, modification and modification are carried out to it, there is the inorganic nano flocculation agent of the attapulgite loaded metal ion of rapid flocculation and oxygenolysis organic contamination.
The technical solution used in the present invention is such: the inorganic nano flocculation agent of attapulgite loaded metal ion, and described inorganic nano flocculation agent mixes post-drying by attapulgite clay with the mixing solutions of aluminium, titanium, lanthanum, cerium and makes.
Further, the ratio of the mixing solutions of described attapulgite clay and aluminium, titanium, lanthanum, cerium is 0.5 ~ 1: 3 ~ 4.
