Embodiment 1

[0035] Embodiment 1: environment-friendly biomass carrier preparation

[0036] In this embodiment, the raw material straw is used to burn the biomass charcoal, and then the straw biomass charcoal is modified to obtain an environment-friendly biochar carrier, which can be used as the substrate of the ecological floating bed. For the biochar obtained by burning agricultural waste straw, the following two organic substances are used to modify: ① polypropylene ② polyacrylamide, and the specific preparation method of the environmentally friendly biomass carrier is as follows:

[0037] Biochar modification: Mix polypropylene and biochar evenly in proportion. In this embodiment, 8 test groups with different mixing ratios are set at the same time, and the mass percentages of biochar in the mixture are respectively 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85% . For each test group, the mixture of polypropylene and biochar was soaked in 1 mg / L polyacrylamide solution for 2 hours, and then b...

Abstract

The invention discloses an ecological floating bed prepared from a biomass carbon source and a substrate and preparation method of the ecological floating bed. Conventional ecological floating bed substrates are improved. Polypropylene and polyacrylamide are adopted for modifying biomass carbon. The substrate of the ecological floating bed has high overall strength and durability, great film forming conditions and a high film forming rate. In practical application, the biomass substrate can be used not only as a raw material for slow release of the carbon source but also as a carrier of a microorganism film formed on the substrate of the floating bed. The ecological floating bed with the substrate has a great disposal effect on water with a low carbon-nitrogen ratio. The ecological floating bed not only solves the problem that biomass waste is difficult to dispose but also can utilize the great biological affinity performance to dispose river water with a low carbon-nitrogen ratio, andthe substrate is an improvement in the current ecological floating bed substrates.

Description

technical field [0001] The invention relates to the fields of ecological floating beds and agricultural non-point source pollution, in particular to a method for treating river sewage by using agricultural waste straws as ecological floating bed substrates. Background technique [0002] Due to long-term urbanization and industrialization, the structure and function of more than 60% of rivers, lakes and wetland ecosystems in my country have been damaged and affected to varying degrees. Although many river channel management and water body restoration projects have been carried out, the trend of water quality deterioration has not been fundamentally resolved. The problem of water eutrophication still has a serious impact on the production and life of residents. As one of the effective methods to improve the eutrophic water body of the river, the ecological floating bed technology uses the synergistic effect of plants and microorganisms to remove nitrogen, phosphorus, organic ma...
