dilution discharge

There is a linear relationship between the average dilution and dimensionless downstream distance; DBV jet has better effect of dilution as compared with the round jet of the same nominal diameter in coflows under the same volume of discharge.

平均稀释度和无量纲的沿程距离之间存在线性关系，相比于具有相同名义直径的同向流动环境中的圆射流，在相同排放流量条件下，DBV射流具有更好的稀释效果。

Traditional dilution and discharge are that can cause heavy environmental pollution, and because agricultural waste water contain a large amount of nutriment, which can utilize two times and reduce the input-output ratio of agricultural production, reduce the production cost.

传统的稀释排放会造成很大的环境污染，并且由于农业废水中含有大量的营养物质，完全可以二次利用，减少农业生产的投入产出比，降低生产成本。
