Embodiment 1

[0072] Based on the needs of overcoming the insufficiency of a single treatment method, improving treatment efficiency and reducing costs, the present invention adopts a method for primary treatment of algae MFC and secondary treatment of glyphosate wastewater by MFC of reed wetlands, which specifically includes the following operation steps:

[0073] (1) Synthesis of glyphosate-containing agricultural wastewater:

[0074] Five groups of wastewaters A, B, C, D, and E were prepared, and the glyphosate concentration was arranged in a gradient from low to high (0, 5, 10, 50, 100 mg / L), and the glyphosate concentration of group A was 0 mg / L. , the glyphosate concentration in the two devices in each group was consistent. The synthetic wastewater was designed to simulate agricultural surface runoff. Except for the concentration of glyphosate, the other components of the simulated wastewater between different groups were the same, including sucrose (89.05mg / L), (NH) 4 )2SO 4 (14.50...

Abstract

The invention relates to the field of pesticide wastewater treatment, in particular to a system and method for treating glyphosate agricultural wastewater and application. In order to solve the problem that the effect of treating glyphosate-containing wastewater by a single method is poor, the invention provides a system for treating glyphosate agricultural wastewater, and the system comprises an algae MFC primary treatment system and a wetland MFC secondary treatment system which are sequentially communicated, the surface of a cathode in the algae MFC primary treatment system is covered with algae, and wetland plants are planted in the cathode in the wetland MFC secondary system. The efficient treatment of glyphosate by the algae MFC system is exerted, the efficient purification of water quality by the wetland MFC is ensured, the wastewater can be removed, and the electric energy can be generated.

Description

technical field [0001] The invention relates to the field of pesticide wastewater treatment, in particular to a system, method and application for treating glyphosate agricultural wastewater. Background technique [0002] The disclosure of information in this Background section is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. [0003] Glyphosate, the active ingredient present in most herbicides, plays a key role in agricultural production by inhibiting weed growth to ensure crop yields. Pesticide wastewater is a long-term problem that has been plaguing the development of enterprises. It is a stubborn disease of environmental governance in the pesticide industry. Glyphosate is a typical representative. The output of glyphosate is very large, and the wastewater co...
