Aquaculture wastewater treatment agent

Abstract

The invention provides an aquaculture wastewater treatment agent. The aquaculture wastewater treatment agent comprises the following components in parts by weight: 50-60 parts of modified coconut shell powder, 30-40 parts of decomposed soybean meal, 1-3 parts of astaxanthin and 4-8 parts of compound bacteria. By the treatment agent, organic and heavy metal pollutants in wastewater can be effectively removed, the self-purification capability of a water body is improved, and improvement of the water body is promoted.

Description

technical field [0001] The invention belongs to the technical field of water quality conditioning agents, and in particular relates to an aquaculture wastewater treatment agent. Background technique [0002] At present, my country's land-based sewage, marine sewage and mariculture wastewater are seriously polluted. For example, my country's coastal waters are seriously polluted, and many coastal waters are basically inferior to the national Class IV seawater quality standards. They are severely polluted sea areas and seriously affect the quality of life of surrounding residents and cities. Coastline landscape; while the pollution of the aquaculture water itself is becoming more and more serious, and diseases occur frequently. At the same time, due to the influence of exogenous pollutants, the quality of the aquaculture environment is declining. main cause of occurrence.

Problems solved by technology

[0002] At present, my country's land-based sewage, marine sewage and mariculture wastewater are seriously polluted. For example, my country's coastal waters are seriously polluted, and many coastal waters are basically inferior to the national Class IV seawater quality standards. They are severely polluted sea areas and seriously affect the quality of life of surrounding residents and cities. Coastline landscape; while the pollution of the aquaculture water itself is becoming more and more serious, and diseases occur frequently. At the same time, due to the influence of exogenous pollutants, the quality of the aquaculture environment is declining. main cause

[0003] In recent years, intensive aquaculture has developed rapidly at home and abroad, especially in my country, and its aquaculture production has accounted for about 2 / 3 of the world's aquaculture production. However, most domestic aquaculture uses closed waters such as ponds and reservoirs. The self-purification ability is far lower than the eutrophication speed of the water body, and the water environment is greatly damaged. The same area cannot meet the sustainable development of aquaculture for a long time. The application of feed, the use of fungicides and disinfectants, the accumulation of animal and plant carcasses and animal manure lead to a large accumulation of organic matter, nitrogen and phosphorus in the aquaculture water, resulting in the deterioration of the aquaculture water body

According to the research, it is found that the ratio of feed to the total input of nitrogen and phosphorus in the pond is 76.08% and 98.55%, and the antibiotics in the long-term feeding feed can cause antibiotic-resistant bacteria in the animal body. These bacteria have different damages to humans and animals. At the same time, aquaculture The waste water has also caused great harm to the surrounding water environment and ecological environment.
