Embodiment 3

[0049] Treatment methods for aquaculture wastewater, such as Figure 1-4 shown, including the following steps:

[0050] A. Anaerobic digestion treatment:

[0051] The aquaculture wastewater enters the homogenization tank 2 through the feed hopper 1, and after being evenly prepared under the stirring action of the stirring device of the homogenization tank 2, it is passed into the biogas tank 3;

[0052] The aquaculture wastewater forms a mixed state under the action of the stirring device and the reflux spray system in the biogas tank 3, and the sediment produced in the anaerobic digestion process is discharged to the sludge concentration tank 8 through the sludge discharge port. The sludge pump is pumped away, and the remaining aquaculture wastewater is then passed into the upflow anaerobic sludge bed reactor 4;

[0053] The aquaculture wastewater decomposes the organic matter in the remaining aquaculture wastewater into methane and carbon dioxide under the joint action of ...

Abstract

The present invention relates to the technical field of wastewater processing, and discloses an aquaculture wastewater processing system. The system comprises a feed hopper (1), a homogenate pool (2), a biogas pool (3), an upstream anaerobic sludge bed reactor (4), an activated sludge reaction tank (5), a micro-electrolysis reactor (10), an annular aerated biofilter (6) and an ozone disinfection pool (7) that are sequentially connected, wherein the biogas pool is connected with a sludge concentration pool (8). The present invention also discloses an aquaculture wastewater processing method. The method comprises the following steps: anaerobic digestion processing, activated sludge processing, micro-electrolysis reaction, annular aerated biofilter biochemical processing and ozone disinfection. According to the aquaculture wastewater processing system and method thereof, the technology is simple, the concentration gradient in the reaction process is large, and sludge expansion is unlikely to occur; the anti-load shock capability is strong, and the processing effect is good; and by adjusting the operation cycle and controlling the length of time of each working procedure, the effect of removing nitrogen and phosphorus is obvious.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, to a treatment system for aquaculture wastewater, and in particular to a treatment method for aquaculture wastewater. Background technique [0002] Livestock and poultry breeding wastewater has a lot of suspended solids, high ammonia nitrogen concentration, high organic concentration, and strong odor. In terms of its discharge, the discharge of organic matter is twice the discharge of industrial and urban domestic waste, and it also contains The characteristics of pathogens excreted by poultry are difficult to deal with, and it is difficult to meet the discharge standards after treatment by traditional processes. At present, most of the aquaculture wastewater adopts natural biological treatment technology, anaerobic treatment technology, aerobic treatment technology, mixed treatment technology and other biological treatment processes. The effect of single aerobic and anaerobic treatment...
