Embodiment Construction

[0004] The present invention prepares the method for polymerized aluminum sulfate barium chloride, (1) after 1 ton of hydrochloric acid of concentration 10-30% and bauxite of 0.2-0.5 ton are placed in reactor, react for 1-3 hour, stand 2- 4 hours, (2) Take the supernatant and 0.1-0.3 tons of barium sulfate into the reaction kettle, react at 60-120°C for 2-3 hours and let stand for 2-5 hours to make polyaluminum sulfate barium chloride liquid .

[0005] The decolorization treatment method of organic sewage with the polyaluminum sulfate barium of above-mentioned preparation is,

[0006] Dilute the polyaluminum sulfate barium solution with clear water to a concentration of 10-30%, and the volume ratio of the sewage to the diluted polyaluminum sulfate barium solution is 1000:1-5, and the polyaluminum sulfate barium solution in Add it into the sewage under stirring, and stir for 5-10 minutes to decolorize the sewage, and the decolorization rate reaches more than 80%.

Abstract

The invention discloses polyaluminum barium sulfatochloride, a preparation method thereof and a method for using the polyaluminum barium sulfatochloride to treat sewage, and relates to sewage treatment. The invention aims to provide polyaluminum barium sulfatochloride which has high decolorization ratio to organic sewage, a preparation method thereof and a method for using the polyaluminum barium sulfatochloride to treat the sewage. The technical proposal of the invention is as follows: the polyaluminum barium sulfatochloride is a mixed liquid of polyaluminum chloride and polybarium chloride. The method for preparing the polyaluminum barium sulfatochloride comprises the following steps: 1 portion of hydrochloric acid with a concentration of between 10 and 30 percent and 0.2 to 0.5 portion of alumina clay react in a reaction kettle for 1 to 3 hours and then are kept stand for 2 to 4 hours, and a supernatant fluid is taken to react with 0.1 to 0.3 portion of barium sulfate in the reaction kettle for 2 to 3 hours at a temperature of between 60 and 100 DEG C and then are kept stand for 2 to 5 hours to obtain a polyaluminum barium sulfatochloride liquid. The invention is used for the sewage treatment.

Description

Technical field: [0001] The invention relates to a kind of sewage treatment, in particular to a kind of polymerized barium aluminum sulfate and its preparation method and its method for treating sewage. Background technique: [0002] For the decolorization treatment in organic wastewater, ferrous chloride, ferrous sulfate, aluminum sulfate or polyaluminum chloride solution are commonly used for treatment, but the decolorization rate is low, generally not more than 20%. Invention content: [0003] The purpose of the present invention is to provide a kind of polyaluminum sulfate barium chloride that the decolorization rate of organic sewage is high and its preparation method and its method for treating sewage. The technical scheme of the present invention is a polyaluminum sulfate barium chloride, which is characterized in that: it is a mixed solution of polyaluminum chloride and polybarium chloride. A method for preparing polyaluminum sulfate barium chloride is characteriz...
