Fishery breeding sewage treatment pool

The invention discloses a fishery breeding sewage treatment pool which comprises a pool bottom and pool walls. A plurality of sedimentary rocks after acid and alkali treatment are arranged in the pool bottom and the pool walls around. The sedimentary rocks are of irregular shapes, the radiuses of which are 2-5cm, wherein the acid and alkali treatment comprises the following steps: soaking the sedimentary rocks for 2-3 hours in a weak alkaline solution; then putting the sedimentary rocks in a weak acidic solution for 1-2h; and taking out the sedimentary rocks and airing the same. The sewage treatment pool disclosed by the invention has an effective removal capacity on pollutants in fishery breeding sewage. The sedimentary rocks after acid and alkali treatment have a targeted removal effect on pollutants in the breeding sewage and further have pertinence and are strong in pollutant removal effect. The process steps in the pollutant removal process are simplified, the risk of secondary pollution on the sewage by
