Watercourse aquaculture trough sewage acquisition and discharge system

Abstract

The invention relates to a watercourse aquaculture trough sewage acquisition and discharge system. The tail end of a watercourse aquaculture trough is provided with a fish blocking net, and the fish blocking net is flush with or higher than a water level line; an upper brim opening of the watercourse aquaculture trough, aslant toward the front lower part, is provided with a foam guide plate; the tail end of the upper brim opening of the watercourse aquaculture trough is provided with a first sewage acquisition trough, the front part of the sewage acquisition trough is fixedly provided with a gas-liquid separation plate dead against the fish blocking net, the upper end of the gas-liquid separation plate is 10-15cm higher than the water level line, and a water passing opening is formed in the lower end of gas-liquid separation plate which is 50-60 cm from the bottom plane of the watercourse aquaculture trough; the bottom of the watercourse aquaculture trough is transversely provided with a nanometer aerator located between the fish blocking net and the gas-liquid separation plate, and bubbles released by the nanometer aerator adsorb sewage through surface tension of the nanometer aerator and rise to take the sewage into the first sewage acquisition trough; the bottom plane of the watercourse aquaculture trough is provided with a sunken type buffer area in the manner of extending backward from the position of the nanometer aerator, the bottom of the buffer area is provided with a second sewage acquisition trough, and a sewage blocking net is fixedly arranged between the buffer area and the tail end of the upper brim opening of the watercourse aquaculture trough.

Description

technical field [0001] The invention relates to a flowing water aquaculture tank set and sewage discharge system, which belongs to the technical field of flowing water aquaculture tank set and sewage discharge. Background technique [0002] The running water aquaculture tank is used for aquaculture, and generally has a box structure, and the left and right ends are constructed of mesh plates or mesh ropes, through which water flow can pass. [0003] The sewage discharge system of the existing running water aquaculture tank generally sets a sewage collection area at the end of the aquaculture tank, and vertically sets a baffle plate about 1 meter above the bottom at the end of the sewage collection area, and then adopts walking sewage suction 4 pairs of sewage collection The tank is used to absorb sewage. This kind of sewage system has poor sewage collection and sewage discharge effects, and most of the sewage enters the pond with the water flow. How to provide a sewage coll...
