Problems solved by technology

The field return mode refers to the direct application of wastewater to the land. This mode has the advantages of simplicity and economy, but it occupies a large area and has low resource recovery efficiency, which cannot meet the wastewater treatment requirements of the modern intensive farming industry.
Industrialized treatment mode refers to a kind of method that adopts anaerobic, aerobic, anaerobic-aerobic and other processes to treat aquaculture sewage for the purpose of discharge. It is the main treatment method in European and American countries. Its main disadvantages are high energy consumption and treatment cost High, poor impact resistance
The natural treatment mode refers to the treatment of aquaculture sewage by means of natural treatment methods such as oxidation ponds, land treatment or artificial wetland systems. However, the effect of using this mode to treat organic matter is not ideal

Embodiment 1

[0032] like figure 1 As shown, a comprehensive treatment system for aquaculture sewage includes a sewage collection tank 1, a bioreactor 2, an aeration adjustment tank 3, and a coagulation sedimentation tank 4 connected in sequence, and a grid 5 is arranged in the sewage collection tank. The grid 5 is obliquely arranged in the sewage collection tank, and the upper end of the bioreactor 2 is provided with a water inlet 21. The water inlet 21 of the bioreactor is connected with the water outlet 11 of the sewage collection tank, and the water outlet 22 of the bioreactor is connected with the exposure tank. The water inlet 31 of the air conditioning tank is connected, and the water outlet 32 ​​of the aeration regulating tank is connected with the water inlet 41 of the coagulation sedimentation tank; the agitator 6 is respectively arranged in the coagulation sedimentation tank and the aeration regulating tank; the bioreactor A rotating shaft 7 arranged horizontally is installed ins...

Embodiment 2

[0036] like figure 1 As shown, a comprehensive treatment system for aquaculture sewage includes a sewage collection tank 1, a bioreactor 2, an aeration adjustment tank 3, and a coagulation sedimentation tank 4 connected in sequence. The sewage collection tank 1 is provided with an arc-shaped The grid 5, the grid 5 is obliquely arranged in the sewage collection tank, and the mesh of the grid 5 is 50 orders; The water outlet 11 is connected, the water outlet 22 of the bioreactor is connected with the water inlet 31 of the aeration regulating tank, the water outlet 32 ​​of the aeration regulating tank is connected with the water inlet 41 of the coagulation sedimentation tank; the coagulation sedimentation tank and the aeration Stirrers 6 are respectively arranged in the regulating tank; horizontally arranged rotating shafts 7 are installed in the bioreactor, and a plurality of supporting rods 8 are fixedly installed on the rotating shafts 7, and the supporting rods 8 are arranged...

Embodiment 3

[0041] The difference between this example and Example 2 is that the preparation method of the flocculant used in this example is as follows: fresh potato stems and leaves and rice vinegar are mixed according to the mass ratio of 1:1, placed in a constant temperature oscillator to Stir at room temperature at a rotating speed of 250rpm for 80 minutes, filter after standing for 20 minutes, and get the resulting filtrate; add xanthan gum to the resulting filtrate, the quality of the added xanthan gum is 1% of the quality of potato stems and leaves, mix, and then mix at 300rpm Stir at room temperature for 60 minutes, place in an oven for drying, and set the oven temperature to 80°C; place the dried product in a muffle furnace for roasting at a roasting temperature of 500°C for 3 hours, cool to room temperature, and use a ball mill to roast The product is ground to a particle size of 600nm; the zeolite powder is ground and pulverized to 200 mesh, and the 200 mesh zeolite powder and ...

Abstract

The invention relates to an aquaculture sewage comprehensive treatment system and also relates to a method for treating aquaculture sewage by the device. The aquaculture sewage comprehensive treatment system comprises a sewage collection tank, a bioreactor, an aeration adjusting tank and a coagulation sedimentation tank which are sequentially communicated, wherein a grille is arranged in the sewage collection tank, and a water inlet is formed in the upper end of the bioreactor and is communicated with the water outlet of the sewage collection tank; a stirrer is arranged in each of the coagulation sedimentation tank and the aeration adjusting tank; a spindle is horizontally arranged in the bioreactor, multiple supporting rods are fixedly arranged on the spindle and are vertical to the spindle, spiral blades are fixedly arranged at the free ends of the supporting rods, the outer surfaces of the blades are rough and uneven, and a microorganism degradation inoculant coats the blades. The aquaculture sewage comprehensive treatment system provided by the invention has the advantages that aquaculture pollution degradation efficiency is high and cost is low.

Description

technical field [0001] The invention belongs to the field of aquaculture sewage treatment, and in particular relates to a comprehensive treatment system for aquaculture sewage, and also relates to a method for treating aquaculture sewage by using the above-mentioned device. Background technique [0002] At present, the rapid development of aquaculture has solved the food problem to a certain extent, met people's demand for aquatic products, and solved the problem of relative shortage of natural fishery resources. However, the rapid development of the aquaculture industry has brought serious pollution to the marine ecological environment, which has become a bottleneck that is difficult to break through in my country's aquaculture industry and seriously restricts the sustainable development of my country's aquaculture industry. In marine fish farming, its metabolites account for 20% to 35% of the feeding amount, and the residual bait is 10% to 40% of the feeding amount, which ...
