Abstract
The invention discloses a preparing method for a polymeric phosphate-ferric chloride water purifying agent. Raw materials include pyrite cinder, kieselguhr, hydrochloric acid and disodium hydrogen phosphate. Pyrite cinder is effectively used, waste is turned into wealth, and the problem that pyrite cinder is difficult to dispose is solved; an appropriate amount of phosphate radical is introduced into polymeric ferric chloride and has a polymerization enhancing effect on polymeric ferrum, the purifying effect is good, various pollutant components in water can be effectively treated, and the content of heavy metal and other harmful substances in water is reduced remarkably. The water purifying agent is mainly prepared from pyrite cinder and kieselguhr, is low in cost and free of secondary pollution, and has the advantages of being high in adsorption capacity, good in water purifying effect and high in water purifying speed.
Description
Technical field
The invention belongs to water treatment field, be specifically related to the preparation method of a kind of poly-phosphorus ferric chloride purifying agent.
Background technology
At present China's industrial sulphuric acid produces and mainly becomes sulfur dioxide by pyrite burning, purified, catalysis oxidation,
Absorb and prepare.Producing substantial amounts of pyrite cinder in roasting process, it is mainly composed of the oxide of ferrum, three oxidations two
Aluminum, silicon dioxide, the most also calcium oxide, magnesium oxide, lead, zinc, selenium, arsenic, phosphorus etc., not only land occupation, pollution environment, and
Cause underground water pollution, always one of difficult problem becoming Sulphuric Acid Enterprises.And the oxide of the ferrum in pyrite cinder, be prepare poly-
How one of raw material of phosphorus ferric chloride purifying agent, therefore, utilize pyrite cinder to prepare poly-phosphorus ferric chloride purifying agent, thus become useless
For treasured, it it is a direction of current pyrite cinder research.
