对新型超微气泡增氧装置的探讨

AN APPROACH OF THE AERATOR BY USING EMULSION

利用超微气泡增氧的方法进行高密度活鱼暂养及鱼苗、成色公路运输已获得很好效果。但采用的溶气罐──水泵──氧气瓶──释放器组成的装置体积较大、造价较高。为此．本文作者设计并在实验室内试验成功了一套用水泵、射流器和释放器组成的新型超微气泡增氧装置。在静水水槽中试验的结果表明，采用新装置增氧时，可使鱼水比达到1：1。

The technique of aeration by using emulsion in short-term aquaticing fishand in transporting living fish and fingerling achieved good results. In fact, so-called'Emulsion' is a mixture of innumerable dense ultramicro gas bubbles and saturated solution.This equipment by using an aerator set (pressurized container - water pump - oxygencylinder-release gear) not only has bulky, but also is expensive. In this paper the designfor an aerate system as a new equipment was indicated. In laboratory a new aerator by usingemulsion was tried out- It is composed of two whirl water pumps. One is water effluxtor andthe other is releasing gear and system of pipeline. The results of indoor experiment showedthat the solubility of oxygen in water of 20℃ can amount to 12. 6 mg (oxygen)/1 (water) byusing the new aerator and after 4 hours in static state this value can still amount to 9. 17 mg(oxygen) /1 (water).
