Problems solved by technology

[0004] At present, the water treatment agents mainly include cationic flocculants, anionic flocculants and zwitterionic flocculants. Among them, cationic flocculants are the most widely used ones. There are deficiencies in both the sewage treatment effect and the processing capacity of the dehydrator, and it is difficult to meet the treatment requirements of tail water, and the preparation equipment of cationic flocculants, anionic flocculants and zwitterionic flocculants is complicated and the cost is high

Embodiment 1

[0048] Such as figure 1 As shown, an aquaculture tail water treatment agent, the aquaculture tail water treatment agent is composed of the following components by weight: 30 to 40 parts of Rhodococcus erythroflatus flocculant, 20 to 30 parts of Bacillus subtilis flocculant and 10 ~20 parts of quaternized acrylamide flocculant.

[0049] A preparation process of an aquaculture tail water treatment agent, the specific steps are as follows:

[0050] Step 1. Preparation of Rhodococcus erythropolis fermentation broth: Inoculate Rhodococcus erythrococcus in the culture medium and culture it at 28-30°C and 130-140rpm for 12-16 hours to obtain Rhodococcus erythropolis seed liquid. Rhodococcus erythroflates seed liquid is added to the high-temperature-treated starch wastewater, and fermented at 28-30°C and 130-140rpm for 20-30 hours to obtain Rhodococcus erythroflates fermentation liquid;

[0051] Step 2, preparation of Bacillus subtilis fermentation liquid: inoculate Bacillus subtili...

Embodiment 2

[0057] Embodiment 2 is a further improvement to Embodiment 1.

[0058] Such as figure 2 , 4 , 5, 6, 7, 8, 9, 10, and 11 show a preparation device for aquaculture tail water treatment agent, comprising two groups of fermentation broth preparation components, flocculant extraction components and composite mixing components, characterized in that: Fermentation broth preparation components include strain tube 1, tube cover 2, No. 1 electric heating ring 3, No. 1 temperature sensor 4, L-connecting tube 5, double-chamber fermentation box 6, closing cover 7, and No. 2 electric heating ring 8. The No. 2 temperature sensor 9 and the liquid discharge pipe 10; the cylinder cover 2 is threadedly connected to the top of the strain liquid cylinder 1, the No. 1 electric heating ring 3 is embedded on the inner wall of the strain liquid cylinder 1, and the No. 1 temperature sensor 4 Installed on the inner wall of the spawn liquid cylinder 1, the No. 1 electric heating ring 3 is equidistantl...

Embodiment 3

[0062] Embodiment 3 is a further improvement to Embodiment 2.

[0063] Such as figure 2 , 3 , 4, 5, and 6, also includes linkage stirring components,

[0064] The linkage stirring assembly includes a connecting rod 11, a connecting plate 12, a double-axis motor 13, a driving pulley 14, a stirring rod 15 for the strain liquid, a stirring rod 16 for the strain liquid, a driving pulley 17, a stirring rod 18 for the fermentation liquid, and a fermentation liquid stirring rod 18. Liquid stirring sub-rod 19, No. 2 transmission pulley 20 and transmission belt 21, connecting rod 11 is welded and fixed on the side wall of strain liquid cylinder 1, connecting plate 12 is arranged on the end of connecting rod 11, and biaxial motor 13 is screwed on the connecting plate 12, the driving pulley 14 is installed on the two output shafts of the biaxial motor 13, the spawn liquid stirring rod 15 rotates and runs through the center of the cylinder cover 2, and the spawn liquid stirring rod 16 ...

Abstract

The invention discloses an aquaculture tail water treatment agent, which is prepared from the following ingredients in parts by weight: 30 to 40 parts of rhodococcus erythropolis flocculant, 20 to 30 parts of bacillus subtilis flocculant and 10 to 20 parts of quaternized acrylamide flocculant. The rhodococcus erythropolis flocculant and the bacillus subtilis flocculant are mixed to form a mixed biological flocculant, the mixed biological flocculant and the quaternized acrylamide flocculant are compounded to produce the aquaculture tail water treatment agent, and the prepared aquaculture tail water treatment agent has the advantages of being non-toxic, harmless, biodegradable and free of secondary pollution. The quaternized acrylamide flocculant is beneficial to improving the bridging effect and the characteristic adsorption effect of the aquaculture tail water treatment agent, and the flocculation performance is improved; meanwhile, the addition amount of the quaternized acrylamide flocculant is small, the raw materials of the mixed biological flocculant are low in price and easy to obtain, and the preparation cost is reduced; in addition, the preparation method is simple, rapid production of enterprises is facilitated, and the production cost of the enterprises is reduced.

Description

technical field [0001] The invention relates to the field of tail water treatment agents, in particular to an aquaculture tail water treatment agent, a preparation process and a preparation device. Background technique [0002] Aquaculture is the waters that humans use for breeding. According to the ecological habits of the breeding objects and the different requirements for the environmental conditions of the waters, aquaculture technology and facilities are used to engage in aquatic economic animals and plants. According to the nature of the waters, it is divided into marine aquaculture and freshwater aquaculture. In the process of aquaculture, aquaculture tail water will be produced. Aquaculture tail water refers to the unused aquaculture water discharged from the aquaculture system to natural waters during or after the aquaculture process. Before the aquaculture tail water is discharged, It needs to be harmlessly treated before it can be discharged into the environment....
