Integrated water purification system for aquaculture water

Abstract

The invention discloses an integrated water purification system for aquaculture water. The integrated water purification system comprises a water inflow cabin arranged in a water tank, a water purifying device, a pollutant discharging device, a functional device and a water draining cabin, wherein the water purifying device is arranged between the water inflow cabin and the water draining cabin and is used for filtering and purifying the to-be-purified water; the functional device is arranged in the water inflow cabin, the water purifying device and the water draining cabin and is used for performing the temperature regulation, sterilization and aeration treatment on the purified water; the pollutant discharging device is arranged at the bottom of the water tank and is used for discharging precipitate impurities; the water tank is arranged as an opening connected water tank; a water pump is arranged on one side of the water draining cabin, and the purified water is discharged through the water draining cabin; the to-be-purified water is discharged into the water inflow cabin; the to-be-purified water is purified by the water purifying device, is subjected to temperature regulation and sterilization through the functional device and then is drained through the water draining cabin; and the precipitates at the bottom of the water tank are controlled and discharged by the pollutant discharging device. According to the invention, a plurality of water treatment devices are integrated in the same purifying tank, so that the construction cost and the maintenance cost can be saved, the management and operation are convenient, and the integrated water purification system is suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of aquaculture devices, in particular to an integrated water purification system for aquaculture water. Background technique [0002] At present, the treatment of wastewater produced by aquaculture in my country generally adopts the model of industrial aquaculture water circulation, that is, the multi-stage treatment of wastewater, which is sequentially processed through multiple links such as aeration tanks, sedimentation tanks, disinfection tanks, and aeration tanks, and finally re-entered. For aquaculture ponds, this method of aquaculture water circulation and purification takes up a lot of space and has high maintenance costs. Other wastewater treatment methods include: directly discharge the breeding wastewater, or use circulating water purification equipment to purify the wastewater. Direct discharge of aquaculture wastewater not only wastes water resources, but also pollutes the environment; although ...

AI Technical Summary

Problems solved by technology

Direct discharge of aquaculture wastewater not only wastes water resources, but also pollutes the environment; although the use of circulating water purification equipment can achieve water purification effects, the purchase cost is too expensive, the equipment is sophisticated, and it is not suitable for long-term use, and the replacement of filter materials is labor-intensive and time-consuming
