Method for processing aquaculture wastewater containing antibiotics by utilizing plant floating bed

Abstract

The invention discloses a method for processing aquaculture wastewater containing antibiotics by utilizing a plant floating bed, belonging to the field of wastewater pollution treatment. The method comprises the following steps: 1) plant pre-culture: cleaning Italian rye grass, utilizing pre-configured aquaculture wastewater to acclimate and culture for 7-10 days in a laboratory, thus enabling the Italian rye grass to adapt to wastewater; and 2) wastewater treatment: adding prepared aquaculture wastewater containing antibiotics into a cuboid container slot, transplanting the Italian rye grass after acclimation and culturing to a floating bed carrier, placing the floating bed on the surface of aquaculture wastewater, and staying for 20-35 days. The invention not only can take away a great amount of nitrogen and phosphorus nutrients from aquaculture wastewater, thus inhibiting algae growth, improving water quality, and simultaneously realizing the purpose of directly discharging or recycling aquaculture wastewater. The harvested rye grass also can be used as livestock and poultry feed or used for centralized recycling treatment, and recovery of usable nutrient elements in plant body.

Description

Technical field: The invention belongs to the field of pollution prevention and control of farm wastewater, and more specifically relates to a method for treating antibiotic-containing breeding wastewater by utilizing a plant floating bed. Background technique: With the rapid economic development in rural areas of our country, the livestock and poultry breeding industry has become the main source of farmers' income. However, due to the low level of large-scale farming, most of them lack effective waste treatment facilities, so the pollutants produced by livestock and poultry production are often discharged directly. into natural water bodies, resulting in the pollution of surface water and even groundwater. Sulfonamide antibiotics are a class of broad-spectrum antibacterial drugs developed in the 1930s. They have been widely used in the field of livestock and poultry farming. In recent years, adding veterinary antibiotics to livestock and poultry feed for the purpose of prom...
