To this end: the fish pond culture wastewater is circularly purified, but the purification effect is influenced by the treated water quantity and the water quality of the culture wastewater, and the requirements of the fish pond culture wastewater not only have the tail water treatment effect and the landscape effect, but also can reduce the daily maintenance and the operation cost.
At present, common tail water treatment modes mainly comprise an artificial wetland, a three-tank two-dam type and the like, and the two modes are precipitation, filtration, aeration and aquatic plant absorption modes for treating the tail water, so that the tail water is purified. After the tail water is treated, the tail water is generally discharged into a river environment, and can also be discharged into a water guiding pool to store purified water. At present, in order to save water resources, purified tail water is reused, for example, the tail water is discharged into a pond again or is discharged into a crop field, and plant growth and the like can be promoted.
However, in other bead triangular areas such as bergamot, the arrangement of ponds has unique topography characteristics, most of them are even piece type, ladder type and take long and narrow structure, this kind of area uses the aforesaid processing method to be required to set up longer pipeline circuit and adopt high-power pump certainly, for example be provided with a plurality of pipelines on leading the pond now, every pipeline corresponds a pond of intercommunication, communicate corresponding pond and diversion pond each other through the pipeline, and to satisfy and pump the water of leading the pond to each pond one by one and use, need adopt high-power pump (more than 90 KW) to carry, therefore the energy consumption is big, with high costs, and need lay longer pipeline, and the pipeline buries underground more, so also need higher construction cost, the cost of later maintenance is also higher.
