Problems solved by technology

Because the process of energy conversion and contact reaction between the tourmaline ball and water is limited to a thin layer on the outer surface of the ball, the tourmaline inside the ball does not play any role, which is tantamount to wasting

Abstract

The invention discloses a zeolite supported nano tourmalinite material and a preparation method and applications thereof. The preparation method comprises the following steps: subjecting tourmalinite to a superfine nano-sizing treatment to obtain tourmalinite nano powder, preparing tourmalinite nano slurry; soaking zeolite in the tourmalinite nano slurry, carrying out ultrasonic stirring so as to loading nano tourmalinite on the inner channels and surface of zeolite, filtering, drying, and burning the mixture at a temperature of 500 to 700 DEG C to obtain the zeolite supported nano tourmalinite material. The zeolite supported nano tourmalinite material can remove ammonia nitrogen in slightly polluted drinking water, and does not have any side effect. The ammonia nitrogen removal rate can reach 90% or more. The provided material is a novel material for deeply removing ammonia nitrogen in slightly polluted drinking water, has an important application value and theoretical significance, and has very important meaning for solving the problems of severe lack of water resources and ammonia nitrogen pollution of drinking water.

Description

technical field [0001] The invention belongs to the technical field of ecological environment materials, and more specifically relates to a zeolite-loaded nano-tourmaline material and its preparation method and application. Background technique [0002] At present, ammonia nitrogen pollution is common in drinking water in my country. Currently, the treatment technologies used to remove ammonia nitrogen in drinking water mainly include aeration method, break point chlorination method, ion exchange method and biological method. The aeration method is to increase the pH value to discharge the ammonia nitrogen in the water into the atmosphere, causing pollution to the atmosphere, and the ammonia nitrogen will return to the water body, and the cost of this process is also relatively high. Although the breakpoint chlorine addition method can effectively remove ammonia nitrogen, the presence of chlorine is harmful to the human body. Ion exchange refers to the ion exchange process ...
