Description
Technical field
The invention belongs to water treatment field, and in particular to a kind of preparation method of inorganic polymer water purification agent.
Background technology
China's industrial sulphuric acid production at present mainly by pyrite burning into sulfur dioxide, purified, catalysis oxidation,
Absorb and be made.Substantial amounts of pyrite cinder is produced in roasting process, its main component is the oxide of iron, three oxidations two
Aluminium, silica, also calcium oxide, magnesia, lead, zinc, selenium, arsenic, phosphorus etc. in addition, not only land occupation, pollution environment, and
Underground water pollution is caused, always as one of problem of Sulphuric Acid Enterprises.And the oxide of the iron in pyrite cinder, be prepare it is poly-
One of raw material of chloro sulphuric acid silicic acid is closed, therefore, how using pyrite cinder to prepare polymerization ferric chloride purifying agent,
It is a direction of current pyrite cinder research so as to turn waste into wealth.
The content of the invention
, should the invention provides a kind of preparation method of inorganic polymer water purification agent in order to make up the deficiencies in the prior art
Water purification agent solves the reluctant problem of pyrite cinder, and its pollutant component that can effectively go in water removal, Er Qiejing
Change speed is fast, cost is low.
The technical solution adopted in the present invention is as follows：
A kind of preparation method of inorganic polymer water purification agent, producing the raw material of polymerization ferric chloride purifying agent includes pyrite
Slag, diatomite, sulfuric acid, hydrochloric acid, oxidant and catalyst, are concretely comprised the following steps：
（1）Pyrite cinder and diatomite in powder are broken to 200~400 mesh, it is stand-by.
（2）Sulfuric acid and hydrochloric acid are added in the reactor that pressure is 0.2~0.6Mpa, is heated to 40~70 DEG C.
（3）By step（1）The powder of acquisition is added in reactor, is stirred 1~3 hour.
（4）Oxidant and catalyst are added in reactor, are heated to 50~60 DEG C, is stirred 3~6 hours.
（5）By step（4）Solution in middle reactor cools down by standing, you can obtains poly-ferric sulfate chloride water purification
Agent.
Further, the oxidant is oxygen or sodium chlorate.
Further, the catalyst is nitric acid.
The present invention has following beneficial effect：
The preparation method of the polymerization ferric chloride purifying agent of the present invention, effective utilization to pyrite cinder is realized, become useless
For treasured, solve the reluctant problem of pyrite cinder, and during water purification agent progress water body purification, its coagulation process institute shape
Big into alumen ustum, sedimentation is fast, and dewatering performance of sludge is good, non-secondary pollution, has good clean-up effect, can be to a variety of in water
Pollutant component is effectively treated, and significantly reduces the content of the harmful substance such as heavy metal in water, and the water purification agent mainly uses sulphur
Iron ore slag and diatomite are made, and cost is low, will not produce secondary pollution, while its strong adsorption force, good with purifying water effect, only
The characteristics of water speed is fast.
