Problems solved by technology

[0008] However, it has been found through practical application research that some of the current tail water treatment and recycling systems have poor water purification effects, some are prone to spread and outbreaks of parasitic diseases (such as small melon worms, etc.), and some are inconvenient to maintain and have high treatment costs

Embodiment 1

[0027] A breeding tailwater ditch circulation treatment system, which includes a sedimentation ditch, a sewage collection cone-bottomed circular pond 9, an aeration pond 11 and an ecological pond 12; the tailwater pipe 2 of the pond or the factory culture workshop 1 communicates with one side of the sedimentation ditch , the other side of the sedimentation ditch communicates with the upper part of one side of the sewage collection conical bottom circular pool 9 through the fence 5 to form a tangential water inlet channel; The upper part of one side of the aeration tank 11 is communicated; the upper part of the other side of the aeration tank 11 is communicated with the ecological pond 12 through the secondary filter dam 13, and the bottom of the aeration tank 11 is placed with a nano aeration disc 14; The bottom of the bottom round pool 9 is connected with a silt pumping device 16 through a silt discharge pipe 15; an underwater ultraviolet lamp is placed in the middle of the se...

Embodiment 2

[0029] A breeding tail water ditch circulation treatment system, which includes a sedimentation ditch, a sewage collection cone-bottomed round pond 9, an aeration pond 11 and an ecological pond 12; this system is used as a surrounding separation facility for the breeding area, which plays a role of isolation and protection from the outside world, and also It is convenient to carry out the research on the purification treatment of aquaculture tail water in sections, and optimize the water quality purification mode. The sedimentation ditch is divided into more than one ditch section according to the terrain, and the multiple ditch sections are arranged in series and in steps. The bottom of the upper ditch section 3 is higher than the bottom of the lower ditch section 7, and the upper part of the adjacent ditch section passes through the fence 5 Connected; the bottom of the water inlet end of the ditch section is set horizontally, the bottom of the water outlet end is sunken and i...

Abstract

The invention relates to a culture tail water ditch circulating treatment system. The circulating treatment system comprises a precipitation ditch, a sewage collection conical-bottom round pool, an aeration pool and an ecological pond; a draft tube is communicated with one side of the precipitation ditch, and the other side of the precipitation ditch is communicated with the upper part of one sideof the sewage collection conical-bottom round pool through a fence to form a tangential water inlet channel; the upper part of the other side of the sewage collection conical-bottom circular tank iscommunicated with the upper part of one side of the aeration tank through a primary filter dam; the upper part of the other side of the aeration tank is communicated with the ecological pond through asecondary filter dam; sludge pumping equipment is connected to the bottom of the sewage collection conical-bottom round pool through a sludge discharge pipe; an underwater ultraviolet lamp is arranged in the middle of the sewage collection conical-bottom round pool; the bottom of the water inlet end of the ditch section is horizontally arranged, the bottom of the water outlet end is sunken and inclines towards the water outlet end, and the left and right sides of the water outlet end incline towards the middle to form chutes; a standby blow-off pipe is arranged at the lower end of each chute;and one or more of a biological hairbrush, purified water fishes and an ecological base band is placed in the ditch section according to the characteristics of tail water. The system is good in tailwater purification effect and low in maintenance and operation cost.

Description

technical field [0001] The invention relates to the technical field of aquaculture tail water treatment, in particular to a system for circulating the aquaculture tail water ditch. Background technique [0002] As the world population continues to increase, water resources will soon become a limiting factor for many industries, the nutritional cost of food production will further increase, the demand for high-quality aquatic products in Southeast Asian countries will increase significantly, and the fishing industry will maintain the status quo Or a downward trend, farmed aquatic products will occupy the main market. At the same time, the cost of water for agriculture, especially aquaculture, has increased, and the pressure on the environment has increased. The biggest challenge for agricultural production in the 21st century is to use less resources to produce more than three times the product. The World Bank's Global Fisheries Plan-2030 Fisheries Project initially proposed...
