Embodiment 1

[0038] A method for assaying dissolved organic matter in a duckweed treatment system for aquaculture wastewater, comprising the following steps:

[0039] S1. Detect the Cu concentration in the duckweed treatment system of the aquaculture wastewater, and obtain the Cu concentration in the aquaculture wastewater;

[0040] S2. For the Cu concentration in the obtained aquaculture wastewater, query the preset Cu concentration / fluorescence component data table to obtain the molecular weight and type of dissolved organic matter in the duckweed treatment system for aquaculture wastewater, in which the Cu concentration / fluorescence component data table Including Cu concentration, dissolved organic matter molecular weight and their corresponding mapping relationship, as well as Cu concentration, dissolved organic matter type and their corresponding mapping relationship.

[0041] In this embodiment, query the Cu concentration in the preset Cu concentration / fluorescent component data tabl...

Abstract

The invention discloses a method for determining dissolved organic matters (DOM) in a culture wastewater duckweed treatment system, which comprises the following steps: detecting the heavy metal concentration in the culture wastewater duckweed treatment system, and obtaining the heavy metal concentration in culture wastewater; inquiring a preset heavy metal concentration / fluorescent component datatable to obtain the molecular weight and type of the dissolved organic matters in the culture wastewater duckweed treatment system aiming at the obtained heavy metal concentration in the culture wastewater, wherein the heavy metal concentration / fluorescent component data table includes heavy metal concentration, dissolved organic matter molecular weight, mapping relations corresponding to the heavy metal concentration and the dissolved organic matter molecular weight, heavy metal concentration, dissolved organic matter types and mapping relations corresponding to the heavy metal concentrationand the dissolved organic matter types. The determination method has the advantages of rapidness, stability, reliability, high efficiency and the like, components of the DOM in the duckweed treatmentsystem can be identified, meanwhile, the relation between the components of the DOM and the heavy metal concentration is clear, and the method has a very good application prospect in actual treatmentof culture wastewater.

Description

technical field [0001] The invention belongs to the technical field of biological environmental protection, and relates to a method for measuring soluble organic matter in a breeding wastewater duckweed treatment system. Background technique [0002] In recent years, copper and zinc have been widely used as feed additives in the livestock and poultry breeding industry. Because it is difficult to deal with heavy metals such as copper and zinc in the anaerobic digestion of breeding wastewater, the biogas slurry still contains high concentrations of copper and zinc. The complex pollution of copper, zinc, ammonia nitrogen and total phosphorus poses a severe challenge to traditional treatment methods, including microbial treatment and phytoremediation of pig biogas slurry. [0003] As a phytoremediation technology, the duckweed system is widely used in the treatment of swine biogas slurry. Duckweed is one of the important plant groups for phytoremediation technology of water pol...
