Industrialization ecological treatment circulation utilization system for fish culture waste water

Abstract

Disclosed is an ecological treatment and recycling system for factory fish-farming wastewater, which belongs to the field of fishery cultivation. The system comprises facilities and devices for treating recycle water like a fish pond, an ultra-low axial flow pump, a jet aeration oxygenation facility, a foam separating facility, a pure oxygen supplying device, a temperature control device, artificial wetland and the like, using an open type high-volume feed canal and a backwater canal to replace sealed pipes, using the foam separating facility to replace a protein separator, using the temperature control device of deep well to replace a heating-up and cool-down device, using the jet aeration oxygenation facility to replace an automatic aerator, a gas relay rock and an air pipe, using water plants of the artificial wetland and economic filtering materials to replace purifying filtration devices like a solid-liquid separation device and the like. The invention achieves functions like water lift, aeration, oxygenation, defoaming, temperature control and the like. The invention optimizes and combines a facility engineering technique and a biologic technology to replace expensive and complex water-treating equipment, and has the advantages of safety and dependability, simple management, energy-saving and environment protection, high yield and high grade and the like.

Description

[0001] Technical field [0002] The invention belongs to the field of fish farming, in particular relates to a circulating water treatment method, and is applied to a factory fish farming system. technical background [0003] At present, the equipment-type circulating water purification treatment technology of the factory fish farming system has huge equipment, high energy consumption, complicated operation, high investment and operating costs, and is difficult to popularize and apply. The "Ecological Energy Saving Industrialized Fish Farming Level Double Circulation Water Treatment System" (Patent Application No. 200610018309.9) invented by me does not use expensive equipment and greatly improves and improves the facilities of the fish farming factory, but there is still waste water treatment Related issues such as unsatisfactory efficiency still need to be further improved. Contents of the invention [0004] The purpose of the present invention is to provide an industrial...
