Embodiment 1

[0102] For a certain pond culture (conventional extensive culture mode) water body, since the SS, total nitrogen, total phosphorus, and COD index content mainly need to be removed in the extensive culture water body, module 2 + module 3 + module 4 can be directly used. First pass through module two - biochemical pool, which is composed of Fuweifeng-1 supplemented with amino polysaccharide chelate salt, which can comprehensively improve water pollution indicators, and can quickly and effectively remove phosphorus, nitrogen, and suspended solids; then pass through module three - plant Absorption tanks are used for treatment, and freshwater plants such as reeds, calamus, and hornworts are used to treat N and P; finally, through module 4-clean water enhanced treatment system, advanced treatment is carried out for total nitrogen and total phosphorus indicators to ensure that the effluent indicators are qualified. The treated water can be discharged to public waters.

[0103] Change...

Embodiment 2

[0106] A seawater industrial culture (intensive culture mode) with too high total phosphorus content, most of the intensive culture mode adopts high-density, high-input, and high-yield farming methods, which has a relatively large impact on the environment, and mainly removes SS, total Nitrogen, total phosphorus and excessive organic matter, reduce BOD, adopt module 1 + module 2 + module 4. First pass through module 1-physical precipitation system, and precipitate macromolecular organic matter through chitosan modified filter material; then pass through module 2-biochemical treatment system, composed of phosphorus-fixing bacteria supplemented with amino polysaccharide chelating salt, phosphorus-fixing bacteria have special The phosphorus absorption effect can absorb soluble organic matter in the water body during the growth process and reduce the SS of the water body; then through the module 4-clean water enhanced treatment system, the advanced treatment is carried out for the ...

Embodiment 3

[0110] In a certain eel farm, there are many organic matters in eel breeding, and various pollution indicators of the water body are too high. It is necessary to adopt module 1 + module 2 + module 3 + module 4. After module 1-physical precipitation system, chitosan modified filter material will Part of the colloid is precipitated; then through the module two-biochemical treatment system, it is composed of TC-TD bacteria supplemented with amino polysaccharide chelate salt. TC-TD bacteria has a good denitrification effect, and the amino polysaccharide chelate salt can be TC- TD bacteria provide an inorganic energy source to promote the rapid growth of TC-TD bacteria; then go through module three - plant absorption pool for treatment, and put in seawater plants such as Gracilaria, asparagus, sargassum for treatment; finally through module four - clear water Strengthen the treatment system, do advanced treatment, and do ecological and chemical treatment for aquaculture drug residue...

Abstract

The invention discloses a tail water treatment comprehensive system, an aquaculture tail water treatment comprehensive system and a method thereof. The tail water treatment comprehensive system realizes aquaculture tail water treatment through three methods of physics, chemistry and ecology, the physical method comprises the following steps: on the basis of a quartz sand filter medium, selecting achitosan modified filter material coating, and carrying out adsorption filtration, according to the chemical method, directed chelation chemical treatment is carried out by adding microorganisms assisted by glycosaminoglycan chelate salt aiming at conventional pollution related indexes, antibiotics and antibacterial agents contained in the aquaculture tail water, so that the aquaculture tail water is non-toxic and harmless, the ecological method comprises the following steps: arranging a fresh water aquatic plant system and a seawater aquatic plant system, improving water pollution indexes byan ecological method, and achieving the purpose of deep purification.

Description

technical field [0001] The invention relates to the technical field of water treatment, and more specifically, to a comprehensive tail water treatment system, a comprehensive tail water treatment system for aquaculture and a method thereof. Background technique [0002] The main pollutants in aquaculture tail water are ammonia nitrogen, nitrite, organic matter, phosphorus and fouling organisms. Ammonia nitrogen is the excrement of aquatic animals, and it is also the final product of the decomposition of nitrogen-containing organic matter such as residual bait, feces, animal and plant carcasses, etc. It is easy to cause deterioration of water bodies and is toxic to farmed animals. Nitrite is very toxic to fish. Its presence can cause the ferrous hemoglobin in the blood of fish and shrimp to be oxidized into methemoglobin, which cannot carry oxygen, thereby inhibiting the oxygen-carrying capacity of the blood and causing tissue damage. Oxygen deficiency, aquatic animals' abil...
