叶轮式增氧机是通过电机带动水面叶轮旋转来搅动水面、搅拌气膜和液膜,增加气、液的接触面积,以扩大氧在水中的浓度梯度,提升空气中的氧向水中转移扩散的速度。该增氧机可在水体中形成一个以增氧机为中心的半径10米左右的富氧圈。在池塘试验中,叶轮式增氧机运转80分钟左右,可使1.5米深处的水体溶解氧含量及水温与上层水体保持一致。该增氧效果十分明显,通过使用叶轮式增氧机给养殖水体增效,从而提升养殖水体的品质,如:可迅速解除鱼、虾缺氧浮头、打破池水分层、提高池塘初级生产力、提高养殖密度、提高产量、降低饲料系数、抑制蓝藻“水华"、净化水体、降低CODcr和BOD5、水底去氮固磷、冬季破冰等。
The impeller type aerator stirs the water surface, stirring gas film and liquid film by the impeller rotating driven by the motor, and increases the contact area of gas and liquid, so as to enlarge the concentration gradient of oxygen in water and enhance the speed of oxygen transfer and diffusion from air to water. The aerator can form an oxygen enriched circle with a radius of about 10 meters in the water body centered on an aerator. In the pond test, the impeller type aerator can keep the dissolved oxygen content and water temperature in the water at the depth of 1.5 meters in accordance with the upper water body when it runs for about 80 minutes. The effect of the aeration is very obvious. By using the impeller aerator to increase the efficiency of the aquaculture water body, the quality of the aquaculture water body can be improved, for example, the hypoxic floating head of the fish and shrimp can be quickly relieved, the water layer of the pond can be broken, the primary productivity of the pond can be increased, the aquaculture density can be increased, the yield can be increased, the feed coefficient can be reduced, and the blue-green algae"bloom" can It can purify water, reduce CODcr and BOD5, remove nitrogen and phosphorus and remove ice in winter.
