The invention relates to the technical field of mariculture, in particular to a seawater seedling raising tail water purification treatment system and method.The seawater seedling raising tail water purification treatment system comprises an adjusting tank, a first water pump, a water inlet pipe, a water outlet pipe, a biological filter and an anaerobic treatment device, the first water pump is arranged between the adjusting tank and the biological filter, and the anaerobic treatment device is arranged on the side, away from the adjusting tank, of the biological filter; the biological filter tank comprises a first tank body, volcanic rock biological filler, a supporting plate, a slurry inlet pipe, a slurry outlet pipe and a first slurry pump; the seawater seedling raising tail water is introduced into the adjusting tank, the water quantity is balanced, then the seawater seedling raising tail water is conveyed into the biological filter through the first water pump, suspended solids and insoluble particles in the water are filtered out through the volcanic biological filler, a biological nutrient solution is added to achieve the purification purpose, after a certain amount of raw water is purified, the filtered sludge is subjected to harmless anaerobic treatment, and the treated sludge is recycled. And the sustainable development of aquaculture is ensured.
Description
technical field [0001] The invention relates to the technical field of seawater aquaculture, in particular to a system and method for purifying seawater nursery tail water. Background technique [0002] The rapid development of the aquaculture industry has brought rare development opportunities for seed production. Industrialized seed breeding production is characterized by its high degree of intensification, high degree of automation, high reliability, timely supply, perennial supply, and low cost. The advantages of low cost, good quality, green and environmental protection have suddenly emerged and become the main force in seed production. [0003] The tail water treatment effect of the traditional seawater factory nursery is poor, and the utilization rate of the tail water is low, resulting in a waste of resources. Contents of the invention [0004] The purpose of the present invention is to provide a tail water purification system and method for seawater seedling cult...
