生活污水池塘是一个非常复杂的生态系统，在渔业生产中溶氧是限制因素。本文对生活污水池塘溶解氧的变化规律作了初步的研究，并对其溶氧的人工调节作了试验，提出了一些合理化的建议，从而指导人们更好地利用生活污水养鱼，变废为宝。
Domestic sewage ponds are a very complex ecosystem and dissolved oxygen is a limiting factor in fishery production. This paper made a preliminary study on the variation rule of dissolved oxygen in domestic sewage ponds, and experimented on its artificial regulation of dissolved oxygen. Some rational suggestions were put forward to guide people to make better use of domestic sewage and fish, turning waste into treasure.
