Description
Technical field
The invention belongs to the water treating equipment field, relate to a kind of energy-conservation micro-hole aerator and preparation method thereof.
Background technology
China is the minimum country of water resources per capita.Existing population is more than 1,200,000,000; The Freshwater resources total amount has only 28000 billion cubic meters to account for 6% of water globe resource; And the pollution that these precious water resource are brought by urbanization and industriallization develops along with the continuation of China's economy with society; China is faced with water resources shortage more, the present situation that the pollution of water resources is more serious.Handle in national product and life at the high-efficiency and low-cost of China's water and to occupy crucial status and realistic meaning, whether the advanced person of water treatment equipment and technology, is the important symbol of a national production and standard of living and national civilization degree.The water treatment of China is still in the growth stage at present; Equipment technology is more relatively backward than also with foreign developed country; In order to protect the precious water resources of China, state investment has been built a large amount of sewage works, but at present in these sewage works the technology of employed sewage disposal device also relatively backward; Work-ing life is shorter; And energy consumption is higher, makes the ton cost of water treatment of sewage very high, and the key equipment in the for example present biochemical processing procedure of sewage also is to account for maximum equipment---the aerator of energy consumption in the WWT.Its energy consumption accounts for 70 ~ 75% of entire sewage treatment plant total energy consumption; The energy consumption that inversed umbrella type aerator, brush aeration machine, plate-spinning aerator is arranged like the surface aeration equipment that is adopted in the biochemical aeration of present sewage is all than higher; Energy utilization rate is every kilowatt-hour of oxygenation 1.5 ~ 1.7kg; And adopt the middle micropore of bottom aeration and the utilization ratio of more higher its energy consumption of fine holes aerator efficient is every kilowatt-hour of oxygenation 2.6kg, all exists too high, the inefficient problem of energy consumption according to energy consumption and output ratio.
According to the medium-term and long-term development strategy of China with to requirement on environmental protection; It is major tasks that the protection of reinforcement water resources is curbed environmental pollution; Save energy consumption simultaneously and realize that Sustainable development is a general orientation, so the sewage disposal device of research and development efficient energy-saving is the key that realizes above target.
Chinese patent 201110057524.0 discloses the efficient ultra-fine micro porous aeration head of a kind of bilayer; Comprise that the aperture is that the conventional brown corundum aeration head of internal layer of 150 ~ 250 μ m and the thickness of coating brown corundum aeration head outside surface are 0.3～0.7mm, the aperture is the ultra-fine microporous layers of the corundum of 56 ~ 80 μ m.As basic unit (being internal layer), the aperture is big, intensity is high with conventional brown corundum layer for the efficient ultra-fine micro porous aeration head of this bilayer, and ultimate compression strength and anti-bar intensity are high; Good permeability, resistance is little, helps air in a large number, pass through fast; And when air arrival skin is the ultra-fine microporous layers of corundum, because this layer aperture is fine and closely woven, be dispersed into very thin trickle bubble to get in the water; Because bubble volume is very little; Therefore can the staying in water bottom of long period and can not rise very soon, thus the oxygen in the trickle bubble will fully be absorbed by water, to reach in water the purpose of oxygenation fast.Because bubble is extremely trickle, make the coefficient of oxygen utilization of air in water improve greatly simultaneously.Coefficient of oxygen utilization when at present existing various aerators are worked is 16～35%; Every kilowatt oxygenation capacity is 1.6～3.6kg; And the utilization ratio of oxygen will reach 50～55% during the aeration that air carries out work through this bilayer minute aperture aerator; Every kilowatt-hour oxygenation capacity will reach 5.77kg, improve 60%.But, because aeration head thickness is thicker, cause resistance bigger, more than the about 12000Pa of drag losses, increased energy consumption, and also higher to equipment requirements, need to use spiral gas blower or high pressure positive blower air-supply.
