Embodiment Construction

[0016] The present invention will be further described below in conjunction with specific examples, but the protection scope of the present invention will not be limited.

[0017] A simple preparation method of a zeolite-supported titanium dioxide sewage treatment agent, comprising the following steps:

[0018] (1) Natural zeolite is ground into powdered zeolite with an average particle size of 180 mesh;

[0019] (2) Put the powdered zeolite in a NaCl solution with a concentration of 5%, keep the temperature at 80°C for 2 hours, filter it, wash it with deionized water, and dry it at 110°C;

[0020] (3) Using butyl titanate as precursor and ethanol as solvent to prepare TiO 2 Precursor sol;

[0021] (4) Immerse the zeolite obtained in step (2) into TiO 2 Precursor sol, ultrasonic 30min, filter after standing for 2h, put the zeolite in a vacuum oven, slowly raise the temperature to 110°C at a heating rate of 3°C / min, and keep the temperature for 30min;

[0022] (5) The produ...

Abstract

A simple preparing method for a zeolite-loaded titanium dioxide wastewater treating agent is provided. The method includes grinding natural zeolite, activating through adopting a NaCl solution, dipping into TiO2 precursor sol to fully loading the surface of the zeolite with the sol, and annealing finally to obtain the zeolite-loaded titanium dioxide wastewater treating agent. The method is simple and controllable in process and low in cost. The wastewater treating agent prepared through the method is high in photocatalytic activity, high in adsorbability, capable of deep ammonia nitrogen removing, and good in wastewater purifying effects.

Description

technical field [0001] The invention belongs to the field of sewage treatment materials, and in particular relates to a simple preparation method of a zeolite-loaded titanium dioxide sewage treatment agent. Background technique [0002] Sewage contains a large amount of ammonia nitrogen. If the concentration of ammonia nitrogen in the water body is high, it will cause excessive algae reproduction, consume dissolved oxygen in the water, lead to eutrophication of the water body, cause toxicity to fish and other aquatic animals, and destroy the water ecological environment. Therefore, Effective removal of ammonia nitrogen has become the main goal of sewage treatment. Utilizing the ion exchange performance of zeolite, it can effectively remove ammonia nitrogen in water. Zeolite is a cheap aluminosilicate mineral. Its structure is mainly composed of silicon oxide and aluminum oxygen skeleton. It has the characteristics of catalysis and low density, and is widely used as catalyst...
