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

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to a preparation method of a polymeric ferric sulfate chloride water purifying agent. Background technique [0002] At present, my country's industrial sulfuric acid production is mainly obtained by roasting pyrite ore into sulfur dioxide, followed by purification, catalytic oxidation, and absorption. During the roasting process, a large amount of pyrite slag is produced, the main components of which are iron oxide, aluminum oxide, silicon dioxide, calcium oxide, magnesium oxide, lead, zinc, selenium, arsenic, phosphorus, etc. , not only occupies land, pollutes the environment, but also causes groundwater pollution, which has always been one of the difficult problems for sulfuric acid enterprises. And iron oxide in pyrite slag is one of the raw materials for preparing polyferric chloride water purifying agent, therefore, how to use pyrite slag to prepare polymeric ferric ...
