Method for comprehensive treatment of concentrated continuous pond culture tail water

Abstract

The invention discloses a comprehensive treatment method for concentrated continuous pond culture tail water. A culture pond is transformed and upgraded in a centralized continuous pond, a simple and convenient long-distance culture pond water supply system is used for supplying water to the culture pond, a green and healthy culture technology is adopted for culture, and after a culture ditch and a pond dam are subjected to centralized dredging and treatment, advanced culture tail water treatment facilities such as adsorption piles are combined; the breeding ditch is used as a long-distance ecological ditch to collect and treat breeding tail water, most of excessive substances such as total nitrogen, total phosphorus and trace metal in the tail water are removed, and the water quality index reaches the national second-class or above water quality standard. The aquaculture tail water is comprehensively treated in a mode of combining in-situ treatment of the aquaculture pond and ectopic treatment of the ecological ditch, the aquaculture pond does not need to be used as a tail water purification treatment pond, the original production mode of a farmer does not need to be changed, normal operation of tail water treatment and the subsequent maintenance cost are low, and the treatment effect is good. The novel tail water treatment mode is easy to copy and popularize in the later period.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for comprehensive treatment of aquaculture tail water in a concentrated contiguous pond. Background technique [0002] The discharge of aquaculture tail water up to the standard is not only the basic requirement for realizing the green development of fishery, but also a powerful starting point for realizing the green development of fishery. However, the discharge of aquaculture tail water up to the standard is a systematic project, which involves the planning and construction of aquaculture ponds, water supply and drainage systems, aquaculture models, and tail water treatment. Strengthen the construction of aquaculture pond hardware facilities, adopt green and healthy aquaculture technology, and improve the in-situ treatment capacity of aquaculture pond tail water; tap the existing tail water treatment space, and do a good job of ex-situ treatment of aquaculture tail...

AI Technical Summary

Problems solved by technology

Taking the "three ponds and two dams" technology as an example, this technology needs to re-plan 1% to 6% of the aquaculture ponds in the aquaculture area as tail water purification treatment pools; most aquaculture ponds need to lay special pipelines for the collection of aquaculture tail water; tail water treatment The cost of engineering construction, normal operation and subsequent maintenance is too high; the above factors limit the promotion of this tail water treatment model
