technical field

The invention relates to the field of aquaculture sewage treatment, in particular to a device for rapid fermentation and return of aquaculture sewage.

Background technique

Farm sewage treatment mainly includes sewage treatment, sludge treatment and disposal. Aquaculture wastewater is a high-concentration organic wastewater rich in a large number of pathogens. It is directly discharged into the water body or stored in an inappropriate place. It may be washed into the water body by rainwater, which may cause surface pollution. Severe deterioration of water or groundwater quality. Due to the strong leaching property of livestock and poultry excrement and urine, the leaching amount of nitrogen, phosphorus and water-soluble organic matter in excrement and urine is very large. If not handled properly, it will enter the groundwater layer through surface runoff and infiltration to pollute groundwater.

Generally, the wastewater discharged from farms has a high content of suspended solids, up to 160,000 mg/L, and the corresponding organic content is also high. It is necessary to reduce the pollutant load in the liquid through solid-liquid separation; secondly, through solid Liquid separation can prevent larger solids from entering the subsequent processing link, and prevent equipment from being blocked and damaged.

In the process of rapid fermentation of aquaculture sewage, solid-liquid separation generally separates the solid part through a filter, and then treats the sewage. However, after the current technology of solid-liquid separation, there are still a large amount of suspended matter in the sewage, which requires finer If the fine filter is used for the first solid-liquid separation, the sewage will pass through the fine filter slowly, which will affect the work efficiency.
