Description

Technical Field

[0001] The utility model relates to a MABR fish-vegetable symbiotic circulation device system, and relates to the technical field of aquaculture tail water treatment. Background Art

[0002] Aquaponics is a recirculating system that integrates aquaculture and plant cultivation. Wastewater generated during aquaculture is rich in nutrients and organic matter, and if left untreated, it can pollute the aquatic environment. Traditional water treatment methods typically employ biological filters or chemical treatments, but these methods suffer from poor treatment effectiveness and high operating costs. Biofilters are unstable and susceptible to fluctuations in temperature and water quality, resulting in poor results in actual operation. Furthermore, biological filters require long startup and maintenance cycles, resulting in relatively high operating costs. While chemical treatment can quickly remove organic matter and microorganisms from wastewater, it produces chemical waste and pollutes the environment. Chemical dosage and reaction conditions require strict control, making operation complex. Long-term use can also affect organisms in the aquaculture water. Using chemical treatments to treat fish farming wastewater is generally costly, requiring consideration of chemical procurement and dosage control.

[0003] In response to the technical needs of aquaculture symbiotic circulation systems, this utility model proposes a MABR aquaculture symbiotic circulation device system. This system utilizes a combination of MABR technology and plant cultivation to fully utilize nutrients in fish farming wastewater to nourish plant growth, while simultaneously purifying the wastewater through plant absorption and soil degradation. This system not only reduces the cost of treating fish farming wastewater but also enables the recycling of water resources, thereby improving the sustainable development of aquaculture. Furthermore, the aquaculture symbiotic circulation device system can create a favorable ecological environment, promote the mutually beneficial symbiotic relationship between plant growth and fish farming, and improve the yield and quality of aquaculture. Utility Model Content

[0007] Furthermore, the MABR purification tank includes a MABR membrane unit, an air supply pipe, an air supply equipment, a medical stone filter layer and a filter plate. The wastewater is purified by the medical stone filter layer at the bottom of the MABR purification tank and then drips into the sedimentation tank below through the bottom filter plate. The thickness of the medical stone filter layer is 20-30 cm, and the particle size of the medical stone is 4-6 mm.

[0008] Furthermore, the MABR membrane units are installed flatly according to the height of the pool body, with a unit spacing of 300-500 mm. The MABR membrane units are supplied with air by an air supply device through an air supply pipeline, providing microporous aeration for the water body and increasing the dissolved oxygen in the water body.

[0010] Furthermore, the bottom filter plate is made of UPVC material with uniform holes, a hole diameter of 2-3 mm, and a hole center distance of 100 mm, so as to increase the dissolved oxygen in the water by dripping.

[0011] The utility model relates to a MABR fish-vegetable symbiotic circulation device system, which relates to the technical field of aquaculture tail water treatment. The wastewater of the fish pond flows into the upper MABR purification tank by gravity through a bottom connecting pipe. The MABR membrane unit is installed on the upper part of the MABR purification tank. The bottom of the MABR purification tank is provided with a medical stone filter layer. The purified water body drips into the sedimentation tank in the lower layer through the bottom filter plate.
