Embodiment Construction
[0010] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments.
[0011] A sewage treatment method comprises the following steps: introducing ozone micro-nano bubbles into the sewage and arranging activated carbon ceramic composite materials loaded with catalysts in the sewage.
[0012] The ozone micro-nano bubbles are formed by ozone passing through the micro-nano ceramic membrane.
[0013] The pore size of the micro-nano ceramic membrane is 30nm-5μm.
[0014] The catalyst is a rare earth oxide, Cu 2+ , Fe 2+ , Fe 3+ 、Al 3+ 、K + at least one of the
[0015] The present invention purifies sewage through ozone micro-nano bubbles, and at the same time decomposes organic matter rapidly through micro-electrolysis formed by catalysts (metal ions) and carbon to achieve the purpose of fading and reducing COD. Through the above two measures, the effect of sewage p...
