In known systems that symbiotically combine plant and fish cultivation, the upper planting container (02) is rigidly connected to the lower water container (03), so that only the entire system (01) can be rotated. Bending forces from the plants can cause instability. In the invention, the planting container (02) and water container (03) are rotatably mounted on top of each other by means of a rotary bearing (46), so that the planting container (02) can be rotated independently of the water container (03). Furthermore, a support plate (31) is connected to a base tray (08) on the planting container (02) via a support device (11), so that any forces occurring are transferred into the base tray (08). A water circulation between the water container (03) and the planting container (02) is created via an inlet device (19), whereby the inlet device (19) does not rotate with the planting container (02).The water container (02) is mounted on support legs (16) and can also be rotated independently via casters (17). This allows for optimal, separate alignment of the plant container (02) and water container (03) according to functional and aesthetic considerations. A variety of additional components, also serving functional and aesthetic purposes, can be optionally installed. The aquaponic growing system (01) is particularly suitable for home use, where a single large plant is cultivated. With scaling, it can also be used for private food production.

The present invention discloses a modular treatment system and its operational method that enables recovering reuse-quality water from grey water discharged from individual houses and apartments. The present invention serves as a replacement for the existing soak pits where the grey water is disposed of without any treatment, leading to contamination of water environment. The invention integrates anaerobic and aerobic biofilms on natural fibre and various macrophytes to treat greywater effectively. It is particularly suitable for household and community-level applications, offering a sustainable solution to reduce freshwater consumption and mitigate water pollution.

This application provides a method and apparatus for simulating the coupled cycling of large-scale wetland plants and biogenic elements. The method includes: acquiring three-dimensional topographic scatter data and multi-source aquatic environment ecological data of a target area, where the target area is a lake wetland; the multi-source aquatic environment ecological data includes interaction data on the seasonal growth and hydrological rhythms of aquatic and wetland plants, biogenic element absorption data during growth, and biogenic element release data after withering; based on the three-dimensional topographic scatter data and multi-source aquatic environment ecological data, constructing the simulation boundary of the target area and parameters in multiple dimensions, including hydrodynamic field, temperature field, material field, and biogeochemical field; and based on the parameters in multiple dimensions, constructing a coupled aquatic environment ecological model of biogenic element cycling based on the plant growth process. This effectively improves the accuracy and completeness of the simulation of biogenic element cycling processes in lake wetland ecosystems and enhances the prediction of biogenic element transport.

The application provides a modular aquatic higher plant ecological treatment method and system for sea urchin / sea cucumber breeding tail water, and belongs to the technical field of breeding tail water treatment.
