Embodiment 1

[0045]Embodiment 1, a kind of resource utilization method of constant temperature industrialized tortoise culture wastewater, comprises the following steps successively:

[0046] 1), discharge the breeding waste liquid in the constant temperature turtle breeding greenhouse 1 into the sedimentation tank 2 for anaerobic fermentation, and respectively obtain the solid matter located in the lower layer and the waste water located in the upper layer;

[0047] The settling tank 2 is provided with two mutually parallel partitions 21, thereby dividing the inner cavity of the settling tank 2 into three settling areas 20 that are parallel to each other and have the same volume (that is, the settling tank 2 adopts a three-grid overflow design) ; The bottoms of adjacent precipitation zones 20 are isolated from each other, and the tops of adjacent precipitation zones 20 are connected. A cover plate 24 is provided on the top of the sedimentation tank 2 to ensure anaerobic fermentation in ea...

Abstract

The invention discloses a method for resource utilizing isothermal industrial chelonian culture waste water, which comprise the following steps: 1) the culture waste liquid in an isothermal chelonian culture booth (1) is discharged in a sedimentation basin (2) for anaerobic fermentation to obtain solids and waste water; 2) solids are prepared to an organic fertilizer; waste water is entered in a collecting pool (3); 3) waste water is entered in a sewage ditch (4); 4) waste water is entered in an integrated biological pool (6) through a sewage water pump (5), water plants are planted in the integrated biological pool (6) and the aquatic animals are cultured; 5) waste water is flowed in a mixed culture pool (7), fishes are stocked and the water plants are planted in the mixed culture pool (7); 6) waste water is flowed in an aquatic vegetable plantation pool (8), the aquatic vegetables are planted in the aquatic vegetable plantation pool (8), 7) waste water processed in the aquatic vegetable plantation pool (8) is flowed in a tail water discharge channel (10). The method enables reasonable and tight combination of breeding industry and planting industry.

Description

technical field [0001] The invention relates to a comprehensive treatment method for aquaculture wastewater, in particular to a resource utilization method for constant-temperature factory turtle aquaculture wastewater. Background technique [0002] Turtle breeding is a special freshwater industry that has developed rapidly in response to market demand after my country's reform and opening up. Since the breakthrough in the constant temperature industrial breeding technology of turtles in the 1980s, significant economic benefits have been driving the rapid development of turtle breeding. The annual output of aquaculture has increased by more than 200 times in the past 20 years, from less than 1,000 tons in the early 1990s to the current annual output of more than 200,000 tons, with an output value of more than 20 billion yuan, becoming the largest high-end freshwater aquatic product consumed in China one. The rapid development of constant-temperature industrialized soft-shelle...
