Problems solved by technology

This seawater aquaculture wastewater treatment method uses electrocatalytic oxidation to decompose organic matter, ammonia nitrogen, and nitrite nitrogen in seawater wastewater to perform a purification mode, and the purification effect is insufficient.
Chinese patent application CN 10592469A discloses an integrated treatment method for aquaculture wastewater, including sedimentation tanks, biochemical tanks, and plant absorption tanks. The purification method uses multi-channel baffled water celery surface flow wetland to plant hybrid No. 16 water celery to purify wastewater, which is troublesome to operate

Embodiment 1

[0048] Such as Figure 1-2 As shown, a seawater pond culture tail water treatment system includes a first-level sedimentation tank 1, a second-level sedimentation tank 2, a filter-feeding animal purification tank 3, a microbial purification tank 4, and a seaweed purification tank 5 connected in sequence.

[0049] Class I sedimentation tank 1 removes most of the particulate matter through natural sedimentation.

[0050] The second-level sedimentation tank 2 includes an ozone generator 13 and an ozone stirring device (not shown in the figure). The ozone stirring device includes a water inlet pipe, a water pump, and a water outlet pipe. The sewage to be treated enters the water inlet pipe under the suction of the water pump, mixes with the ozone prepared by the ozone generator 13, and then is discharged from the water outlet pipe, and returns to the second-stage sedimentation tank. Through the strong oxidation and flocculation of ozone, the particulate matter and organic matter ...

Embodiment 2

[0057] A seawater pond culture tail water treatment system includes filter-feeding animal purification ponds, microbial purification ponds, and seaweed purification ponds connected in sequence.

[0058] A floating bed is set on the water surface of the filter-feeding animal purification pool, and flower pots are set on the floating bed. There are 4 flower pots per square meter of water surface, and 20 near river oysters are suspended under each flower pot; the plankton and small particulate organic matter. A floating bed is set in the microbial purification tank, and flower pots are set on the floating bed. There are 4 flower pots per square meter of water surface, and 5 filler balls and 1 heavy object are hung under each flower pot in turn, and the filler balls are spaced 5cm apart. Nitrifying bacteria, denitrifying bacteria, Bacillus, Rhodopseudomonas and Lactobacillus acidophilus are placed in the pool water; 1-6 grams of microorganisms are used per cubic meter of water, an...

Embodiment 3

[0063] The aquaculture tail water to be treated comes from a farm in Hainan. The content of particulate matter in the water body is high, and the water body is turbid, which is highly polluted tail water. The original pollutant content is shown in the data before treatment in Table 1 below.

[0064] Table 1 Pollutant content before and after treatment of aquaculture tail water

[0065]

[0066] Adopt the processing system of embodiment 1 to process, and concrete processing method comprises:

[0067] (1) Discharge the aquaculture tail water into the first-stage sedimentation tank through the flow channel, and control the flow rate to 20-25m 3 / h, through natural settlement, most of the particulate matter is removed, and the settled tail water flows into the second-stage sedimentation tank through the U-shaped hidden pipe installed on the wall of the tank.

[0068] (2) Turn on the water pump of the ozone generating device (ozone machine) and the ozone stirring device, and th...

Abstract

The invention discloses a seawater pond breeding tail water treatment system and a seawater pond breeding tail water treatment method. The system comprises a first-stage sedimentation tank, a second-stage sedimentation tank, a filter-feeding animal purification tank, a microbial purification tank and a seaweed purification tank, wherein the tanks are sequentially communicated, and purify tail water. According to the system, proper shellfish, microorganisms and algae varieties are selected to form advantage complementation in purification effect, so that the comprehensive and efficient purification of breeding tail water is realized, the equipment is simple, the use is convenient, and toxic and harmful substances such as organic matters, ammonia nitrogen, suspended matters, COD and the likeaffecting the ecological environment of sea areas in the breeding tail water of southern seawater ponds can be effectively solved.

Description

technical field [0001] The present application relates to the technical field of seawater aquaculture, in particular, to a seawater pond aquaculture tail water treatment system and treatment method. Background technique [0002] With the rapid development of the mariculture industry, the excretion of cultured objects, the decomposition of residual bait and the poor water flow have led to the continuous accumulation of nutrients in the cultured water, seriously threatening the ecological environment of the sea. Feeding high-protein rations and feed, the excrement and residual bait of aquatic animals will be deposited in the water, which will lead to the deterioration of the water quality and ecological environment of the aquaculture water. Once the water quality deteriorates, the feeding and growth of aquatic animals will be seriously affected, and even lead to Poisoning, disease and death occurred. At the same time, aquaculture will discharge a large amount of aquaculture t...
