Abstract

The invention relates to the technical field of aquatic product processing wastewater treatment, and provides an aquatic product processing wastewater treatment system and method. The system comprises a water collecting tank, a grid tank, an electric flocculation tank, an anaerobic fermentation tank, an adjusting tank, a photobioreactor, a microalgae harvesting tank and a clean water tank which are sequentially connected; the grid tank, the electric flocculation tank and the anaerobic fermentation tank are all connected with a sludge treatment device; a water return pipe connected with the regulating tank is arranged on the microalgae harvesting tank, the anaerobic fermentation tank is connected with a biogas utilization system, and the biogas utilization system is electrically connected with the electric flocculation tank. The aquatic product processing wastewater treatment system and method have the advantages of being good in treatment effect, low in operation cost, high in recycling degree, convenient to operate and manage and the like, and are energy-saving and environment-friendly.

Description

technical field [0001] The application belongs to the technical field of wastewater treatment for aquatic product processing, and more specifically relates to a wastewater treatment system and method for aquatic product processing. Background technique [0002] In recent years, with the improvement of people's living standards, the demand for aquatic products is increasing. According to statistics, my country's aquaculture accounts for 70% of the global output, and the total amount of aquatic product processing reaches more than 20 million tons. The aquaculture industry is a typical sunrise industry. [0003] However, there are many problems in the process of rapid development of aquatic product processing. For example, the aquatic product processing industry is a typical high water consumption industry, which produces a large amount of wastewater and seriously pollutes the environment. At the same time, there are too many small processing enterprises and their strength Lim...
