Abstract
The invention relates to a releaser-free sewage gas-floatation device. The releaser-free sewage gas-floatation device comprises a sewage pool and a gas dissolved water pipeline, wherein the front end of the gas dissolved water pipeline is provided with a mixer; the mixer comprises a flaky piece; the upper surface of the flaky piece is provided with a plurality of water outlets; a plurality of water diversion pieces are arranged on the upper end of the flaky piece; a plurality of water holes are formed in the water diversion pieces; the water holes of different water diversion pieces are not overlapped, so that gas dissolved water and sewage are sufficiently mixed, therefore, the collection efficiency of impurities is high, and the water holes are unlikely to be plugged.
Description
Technical field
The application relates to technical field of sewage, specifically, relates to a kind of sewage air-flotation device of exempting from reliever.
Background technology
Air supporting as one efficiently, solid-liquid separation technique fast, start from ore dressing flotation technology, it passes into microbubble intensive in a large number toward water, itself and impurity, grain of wadding a quilt with cotton are adhered to mutually, form the buoyancy aid that overall proportion is less than water, and rely on buoyancy to make it float up to the water surface, thus complete water purification technology that is solid, that be separated.At first, the removal that this technology is mainly used in fat, oil, fiber, grease isodensity are less than the material of water, in the later stage sixties 20th century, this technique is promoted in sewage disposal and drinking water treatment, has been widely used at present in the process of the trade effluents such as oil refining, papermaking, printing and dyeing, electric power, chemical industry, weaving, leather, food, machinery, light industry and city domestic sewage and Drinking Water.Different according to the mode producing bubble, air-float technology is divided into electrolysis (cohesion) air supporting, aeration air supporting and air-dissolving air-float, and wherein pressurized dissolved air flotation technique is one of the most frequently used technique of water treatment.
Pressurized dissolved air flotation technique is a kind of new water technology, and it is widespread use in China and many advanced industrial countries.This new purification of water introduces in pending water by a large amount of micro bubbles discharged in pressure air-dissolving water, utilizes the buoyancy force of the bubble sticked on solid impurity, reach solid, liquid sharp separation, and improve the object of scum silica frost concentrating degree.Pressure air-dissolving water, by after dissolved air release step-down energy dissipating, discharge a large amount of bubbles, but dissolved air release is easy to blocked, needs to split out to clear up, and has had a strong impact on production efficiency.
Application content
The application overcomes shortcoming of the prior art, provides a kind of sewage air-flotation device of exempting from reliever, does not re-use reliever, not easily block, and will be reduced to minimum on the impact of producing.
In order to solve the problems of the technologies described above, the application is achieved through the following technical solutions:
A kind of sewage air-flotation device of exempting from reliever, comprise sewage lagoon and dissolved air water pipeline, the front end of described dissolved air water pipeline is provided with mixing tank, described mixing tank comprises sheet shaped piece, the upper surface of described sheet shaped piece arranges some posticums, the top of described sheet shaped piece is provided with some water diversing sheets, and described water diversing sheet arranges some water holes, and the water hole of different described water diversing sheet is not overlapping.
