The aquatic-organism and plant symbiotic device of this creation,Be have at least one for put in a suitable place to breed aquatic-organism culture zone,An at least microorganism decomposition area,At least one for serike the area Zhi Zai,And one group of hydraulic pipeline; By hydraulic pipeline plan water flow with predetermined order flow through culture zone,Microorganism decomposition area and the area Zhi Zai,I.e. the sewage of the biological waste Han the Shui nationality is first flowed by microorganism decomposition area,It can ensure that sewage can effectively be broken down into nutrition needed for plant,It is conveyed again gives plant absorption to the area Zhi Zai,Filtering efficiency can be improved and reduce energy consumption,And reaches effective and balanced with firm ecological symbiosis.本創作之水族生物與植物共生裝置,係具有至少一供放養水族生物的養殖區、至少一微生物分解區、至少一供栽種植物的植栽區,以及一組輸水管路;由輸水管路規劃水流以預定順序流經養殖區、微生物分解區以及植栽區,即含水族生物排泄物之污水先流經過微生物分解區,可確保汙水能有效被分解成植物所需營養,再輸送其至植栽區予植物吸收,可提高過濾效能與降低能源消耗,以及達到有效與穩固的生態共生平衡。
