China is a big country for aquaculture, according to the data of '2020 Chinese fishery yearbook', in 2019, the total yield of aquatic products in China all the year round reaches 6480.36 ten thousand tons, and the total yield of aquaculture occupies 5079.07 thousand tons. With the pursuit of people for high-quality life, the four Chinese carps of 'green, grass, silver carp and bighead carp' are gradually changed into the cultivation of a plurality of famous and excellent aquatic products such as Chinese mitten crab, micropterus salmoides, mandarin fish and the like as the traditional aquaculture objects. Aquaculture has become an important part of agriculture in China, and meanwhile, the aquaculture industry must become a key development industry on the new course of developing modern agriculture.
In order to adapt to the ever-increasing demand of aquatic product consumption of people, novel culture modes such as intensive culture, Recirculating Aquaculture (RAS), Biological Flocculation Technology (BFT) and the like greatly enrich the production mode of aquaculture. The biological flocculation technology is a novel cultivation technology evolved from the development of the activated sludge technology, and is considered to be one of effective methods for solving the resource and environmental problems faced by the current intensive cultivation. BFT establishes nitrifying and assimilating floccules by regulating external conditions to degrade highly toxic NH in water4 +And NO2 -Converting it to less toxic NO3 -And a microbial biomass. The biological floc mainly comprises suspended particles consisting of residual baits, feces, other metabolites of fishes, protozoa and the like, the representative index of the BFT technology is total suspended particles (TSS), the TSS concentration can be continuously increased along with continuous culture and increase of bait feeding amount, the TSS with a certain concentration can improve the purification capacity of a water body, but at the same time, an excessively high TSS concentration can cause certain harm to a BFT culture system and a culture object and influence the growth performance and immune response performance of the culture object, and a method for directly discharging the water body with an excessively high TSS in production is generally adopted. Because the biological flocs have high nutritive value, if the biological flocs are directly discarded without proper treatment, not only can serious waste of resources be caused, but also a series of environmental pollution problems can be caused. Excessive biological floccule culture waste, just as aquaculture tail water generally restricts the growthThe development of the floccule culture technology, how to effectively utilize the floccule as a resource, is becoming a hot spot of competitive research of numerous scholars.

step 1: precipitating aquaculture tail water containing biological flocs, and removing supernatant to obtain a biological floc concentrated solution;
step 2: filtering the biological floc concentrated solution and collecting to obtain a floc to be used;
and step 3: drying or dehydrating the floc to be used to obtain floc substances;
and 4, step 4: mixing the floccule substance with the soil to obtain a soil-floccule mixture;
and 5: controlling the water content of the soil-floc mixture by spraying water;
step 6: the soil-floc mixture is used for planting plants.
The invention has the beneficial effects that: according to the method, the aquaculture tail water containing the biological flocs is treated and then is matched with soil for seeding economic crops, so that various nutrient elements required for growth can be provided for the crops, the method is a harmless resource utilization method for the biological floc aquaculture waste, and the economic loss caused by directly discarding the floc waste can be reduced; meanwhile, certain economic value is brought in the resource utilization process, and the method has important significance for promoting the resource utilization of the biological flocs.
