      葉輪式增氧機(jī)是通過電機(jī)帶動水面葉輪旋轉(zhuǎn)來攪動水面、攪拌氣膜和液膜，增加氣、液的接觸面積，以擴(kuò)大氧在水中的濃度梯度，提升空氣中的氧向水中轉(zhuǎn)移擴(kuò)散的速度。該增氧機(jī)可在水體中形成一個以增氧機(jī)為中心的半徑10米左右的富氧圈。在池塘試驗(yàn)中，葉輪式增氧機(jī)運(yùn)轉(zhuǎn)80分鐘左右，可使1.5米深處的水體溶解氧含量及水溫與上層水體保持一致。該增氧效果十分明顯，通過使用葉輪式增氧機(jī)給養(yǎng)殖水體增效，從而提升養(yǎng)殖水體的品質(zhì)，如：可迅速解除魚、蝦缺氧浮頭、打破池水分層、提高池塘初級生產(chǎn)力、提高養(yǎng)殖密度、提高產(chǎn)量、降低飼料系數(shù)、抑制藍(lán)藻“水華"、凈化水體、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.
