description The invention discloses a fishery breeding sewage treatment method which comprises the following steps: controlling the flow of pre-treated sewage at 7-10m /h and introducing the sewage into a pollutant removal pool, wherein the pollutant removal pool contains a plurality of adsorption stones after acid and alkali treatment; and performing follow-up treatment on the sewage flowing out of the pollutant removal pool, wherein the adsorption stones after acid and alkali treatment are irregular sedimentary rocks, the radiuses of which are 2-5cm; soaking the sedimentary rocks for 1-3 hours in a weak alkaline solution; then putting the sedimentary rocks in a weak acidic solution for 10-30min; and taking out the sedimentary rocks and airing the same. The sewage treatment method disclosed by the invention has an effective removal capacity on pollutants in fishery breeding sewage. The adsorption stones have a targeted pollutant removal effect on pollutants in the breeding sewage and further have pertinence and are stro
