The present invention relates to the technical field of aquaculture effluent treatment, in particular to an apparatus for microalgae-microorganism synergistic treatment of aquaculture effluent. The apparatus comprises an aquaculture part; the aquaculture part is in communication with an effluent discharge part; the effluent discharge part is in communication with an effluent treatment part; and the effluent treatment part is in communication with the aquaculture part. The effluent discharge part comprises an effluent discharge pipe in communication with the aquaculture part; the end of the effluent discharge pipe away from the aquaculture part is in communication with the effluent treatment part; and an effluent discharge pump is arranged on the effluent discharge pipe. The effluent treatment part comprises a second housing; the bottom end of the second housing is in communication with the effluent discharge pipe; the top end of a side wall of the second housing is in communication with the aquaculture part; the interior of the second housing is provided with a plurality of flow guide plates; and microalgae are inoculated on outer side walls of the flow guide plates. In the present invention, microalgae and original microorganisms in aquaculture effluent form microalgae-microorganism symbionts, which can reduce carbon, reduce nitrogen and remove phosphorus synchronously and have few effects on aquaculture organisms, so that the quality of discharged water can be greatly impro

The invention discloses a method for quantifying complexing distribution balance of a microalgae-heavy metal-organic matter system. The complex equilibrium constant between the heavy metal and the organic matter and the partition coefficient of the heavy metal between the microalgae and the liquid phase can be quantified by measuring the absorption amount of the microalgae to the heavy metal and the concentration or characteristic spectrum of the organic matter in a balanced mixed system of the microalgae, the heavy metal and the organic matter by using the microalgae as an indicator. According to the method, the relationship between the microalgae absorption amount and the organic matter concentration is calculated by utilizing the balance of heavy metals and complexation in a solution, the distribution balance of the heavy metals in microalgae and a liquid phase and the material conservation relationship of the heavy metals and the organic matter, and then the relationship between the microalgae absorption amount and spectral characteristic parameters is established according to the Lambert-Beer law. And a complexing equilibrium constant between the heavy metal and the organic matter component and a distribution coefficient of the heavy metal between the microalgae and the liquid phase are quantified by interpreting the spectral parameters. According to the method, the complex equilibrium constant between the heavy metal and the organic matter component under the ternary sy
