Modified red stilbite water cleaning agent

Abstract

The present invention discloses a modified hematilite water purifying agent. The manufacturing method steps of the water purifying agent are as follows: 1) pulverize the hematilite and mix it with a magnesium-containing compound and an aluminum-containing compound; Add alkali solution to the above mixture, adjust its pH value to 6-8, and make the mixture into a colloidal state; 3) Dry and crystallize the obtained mixture to obtain the modified staphilite water purifying agent. Wherein, the mass ratio of the used hematilite to the magnesium-containing compound and the aluminum-containing compound is 2:1:0.5˜2:3:2. After the hematilite is modified by the manufacturing method of the present invention, it is used to treat COD in domestic sewage, and the removal rate is greater than 75%, and it can also be used to treat the toxic substance Cr in sewage. 6+ , the removal rate is greater than 95%, the post-modification treatment effect is 2 times and 8 times the removal effect of the unmodified staphite, and the production cost of the modification treatment is low, and the process is relatively simple.

Description

(1) Technical field: [0001] The invention relates to a water purifying agent, in particular to a modified hematilite water purifying agent. (two) background technology: [0002] Water is an indispensable material resource in human life and production activities. In recent years, with the rapid development of the economy, the water source pollution caused by industrial sewage discharge and urban domestic sewage discharge has become more and more serious, which has gradually threatened people's health and ecological balance, so how to better improve the quality and purification of water sources Sewage has become an urgent problem to be solved. It is an effective and quick way to purify water quality through the reaction of water purifiers with pollutants in water sources, and it is also an important way to purify water quality. At present, people have developed various types of purifiers, which are used to remove substances and impurities harmful to the human body and the en...

Problems solved by technology

The natural zeolites currently used to prepare water purification materials are mostly modified with clinoptilolite, mordenite, and chabazite as raw materials to prepare various water purification materials. The Chinese invention patent of "Water Agent" discloses a purifying agent that can purify drinking water. It is made of clinoptilolite as a raw material. It has a large surface area and strong adsorption capacity. It can not only effectively defluoride, iron, decolorize and deodorize, but also soften hard water. However, this purifier is only suitable for purifying drinking water and has no effect on domestic sewage. good
