Abstract

The invention discloses a preparing method for a polymeric ferric chlorosulfate water purifying agent. Raw materials include pyrite cinder, kieselguhr, sulfuric acid, hydrochloric acid, an oxidizing agent and a catalyst. Pyrite cinder is effectively used, waste is turned into wealth, and the problem that pyrite cinder is difficult to dispose is solved; when the water purifying agent is used for purifying a water body, alumen ustum is large in the coagulation process, and the water purifying agent is high in settling speed and free of secondary pollution and has a good purifying effect.

Description

A kind of preparation method of polymerization ferric chloride purifying agent
Technical field
The invention belongs to water treatment field, be specifically related to the preparation method of a kind of polymerization 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- Close one of raw material of chloro sulphuric acid silicic acid, therefore, how to utilize pyrite cinder to prepare polymerization ferric chloride purifying agent, Thus turn waste into wealth, it is a direction of current pyrite cinder research.
Summary of the invention
In order to make up the deficiencies in the prior art, the invention provides a kind of polymerization ferric chloride purifying agent and preparation side thereof Method, this water purification agent solves the reluctant problem of pyrite cinder, and it can effectively remove the pollutant component in water, and And purification speed is fast, low cost.
The technical solution adopted in the present invention is as follows:
The preparation method of a kind of polymerization ferric chloride purifying agent, the raw material producing polymerization ferric chloride purifying agent includes sulfur ferrum Ore deposit slag, kieselguhr, sulphuric acid, hydrochloric acid, oxidant and catalyst, concretely comprise the following steps:
(1) pyrite cinder and diatomite in powder are broken to 200~400 mesh, stand-by;
(2) in the reactor that pressure is 0.2~0.6Mpa, add sulphuric acid and hydrochloric acid, be heated to 40~70 DEG C;
(3) powder step (1) obtained adds in reactor, stirs 1~3 hour;
(4) oxidant and catalyst are added in reactor, be heated to 50~60 DEG C, stir 3~6 hours;
(5) by the solution in reactor in step (4) through standing cooling, polymerization ferric chloride purifying agent can be obtained.
Further, described oxidant is oxygen or sodium chlorate.
Further, described catalyst is nitric acid.
The present invention has a following beneficial effect:
The preparation method of the polymerization ferric chloride purifying agent of the present invention, it is achieved that the effective utilization to pyrite cinder, becomes useless For treasured, solve the reluctant problem of pyrite cinder, and when this water purification agent carries out water body purification, its coagulation process institute shape Becoming alumen ustum big, sedimentation is fast, and dewatering performance of sludge is good, non-secondary pollution, has good clean-up effect, it is possible to multiple in water Pollutant component is effectively treated, and significantly reduces the content of the harmful substance such as heavy metal in water, and this water purification agent mainly uses sulfur Iron mine slag and kieselguhr are made, and low cost, will not produce secondary pollution, and its absorption affinity is strong simultaneously, has purifying water effect good, only The feature that water speed is fast.
