Abstract

The invention belongs to the field of environmental protection equipment, and discloses a double-layer high-efficiency superfine-micropore aeration header. The double-layer high-efficiency superfine-micropore aeration header comprises an inner-layer conventional brown corundum aeration header with the pore diameter of 150-250 microns, and a corundum superfine micropore layer coated on the outer surface of the brown corundum aeration header, wherein the corundum superfine micropore layer is 0.3-0.7 mm in thickness and has the pore diameter of 56-80 microns. In the double-layer high-efficiency superfine-micropore aeration header, the conventional brown corundum layer is adopted to serve as a base layer and has the advantages of large pore diameter, high strength, good air-permeability, small resistance, therefore, air can pass through the base layer rapidly in a large quantity; furthermore, when the air reaches the outer layer, namely, the corundum superfine micropore layer, the micropores of the layer are fine and close so that the air is dispersed into very fine bubbles to enter into water so as to rapidly oxygenate the water. Synchronously, the bubbles are extremely fine so that the oxygen utilization coefficient of the air in the water is greatly improved, additionally, the corundum superfine micropore layer is very thin so that the resistance to the air passing through the corundum superfine micropore layer is greatly reduced, therefore, the aims of energy saving and high efficiency are achieved.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment and relates to a double-layer high-efficiency superfine microporous aeration head. Background technique [0002] China is a country with severe drought and water shortage. The total amount of fresh water resources is 2.8 trillion cubic meters, accounting for 6% of global water resources, ranking fourth in the world after Brazil, Russia and Canada, but the per capita is only 2,200 cubic meters, which is only 1 / 4 of the world average. 1 / 5 of the United States is one of the 13 countries with the poorest per capita water resources in the world. With the rapid development of economy and society, our country is now facing the current situation of water shortage and serious water pollution. [0003] Water treatment occupies a very important position in national production and life. The presence or absence of water treatment and the advancement of water treatment technology are one of t...
