Description

Abalone farming circulating purification water treatment system

technical field

The utility model relates to a circulating water purification system in aquaculture, in particular to an abalone breeding circulating purification water treatment system.

Background technique

At present, in my country's factory-based land-based abalone farming, the main method is to extract external sea water and enter it into the aquaculture pond after simple sand filtration, or to extract sand well water for flowing water aquaculture, and the waste water is directly discharged into the sea area through the pipeline. Affected by the sea water, it is unstable. When red tide breaks out in the sea area, the water quality is polluted, or epidemic diseases appear around the farm, it cannot be effectively avoided. At the same time, it also has the disadvantages of high energy consumption and large pollution to the sea area. Some water intake time is also limited. Affected by the ebb and flow of water levels, abalone farming is often restricted by natural conditions, frequent disease outbreaks, and high energy consumption also increases the cost of farming.

Utility model content

The purpose of the utility model is to provide a kind of abalone breeding circulating purification water treatment system which can effectively avoid or reduce the dependence on the external environment, keep the water quality stable, and is suitable for the growth and development of the abalone.

Type activated carbon filter pool, the outlet of the recoil type activated carbon filter pool is connected to the water inlet of the culture pond through the flow channel, and the ozone/ultraviolet disinfection device is installed on the flow channel between the water storage buffer tank and the explosion pool.

The water treatment process is that the water flowing out of the breeding pond passes through the recoil physical filter to remove large particles such as residual bait and feces, which are further clarified by the sedimentation tank, and then pumped to the storage buffer tank by the water pump, and then flows through the ozone/ultraviolet disinfection device to kill Bacteria, viruses, parasite eggs and other harmful organisms in the water body, the disinfected water passes through the degassing tank to remove residual ozone, increase dissolved oxygen in the water body and oxidize part of the organic matter, and then decomposes NH ₃ ^- and NO ₂ ^- in the recoil biological purification tank , H ₂ S and other harmful substances, and finally the recoil type activated carbon filter removes harmful substances such as heavy metal ions and then flows back to the breeding pond for recycling.

The recoil treatment tank described in the utility model is composed of a water inlet chamber, a recoil chamber and a water outlet chamber. A partition wall is arranged between the water inlet chamber and the water outlet chamber. The recoil chamber is located below the water outlet chamber. There is a perforated baffle between them, one end of the baffle is joined with the lower end of the partition wall, and a filter and purification layer is laid on the baffle, and the water inlet chamber and the recoil chamber are integrally connected; at the bottom of the water inlet chamber, a There are drain holes. The water flowing into the water inlet chamber passes through the filter purification layer from bottom to top to the water outlet chamber from the recoil chamber to purify the water.

Compared with the prior art, the utility model has the following advantages: (1) the use of closed circulating water treatment can effectively avoid or reduce the dependence on the external environment, keep the water quality stable, facilitate the prevention and management of diseases, and improve the survival rate, After adding heating equipment, it is easy to control the temperature for overwintering, and it can also greatly reduce energy consumption and cost; (2) It adopts recoil filter purification treatment, which is easy to clean, reduces the burden on the filter layer, and prolongs the use time of filter materials.

Detailed ways

As shown in Figure 1, the present embodiment consists of eight culture ponds A, recoil type physical filter pond B, sedimentation pond C, water pump P, water storage buffer pond D, ozone/ultraviolet disinfection device E, degassing pond F, reflection pond Flush type biological purification pool G and recoil type activated carbon filter pool H are composed. The area ratio among the buffer pool D, the explosion pool F, the recoil type biological purification pool G and the recoil type activated carbon filter pool H is 1:1:2:2:1:1. The irradiation thickness of the single-sided water layer of the ozone/ultraviolet disinfection device should be less than 2cm, and the water flow rate should be adjusted to ensure that the irradiation dose is greater than 20000μw.s/cm ² . Two sets can be installed, one of which is reserved. It is advisable that the inflation rate of the inflatable pipe in the gas explosion pool F be slightly boiling with the water body.

As shown in Figure 2, the above-mentioned recoil treatment tank is composed of a water inlet chamber 1, a recoil chamber 2 and a water outlet chamber 3, a partition wall 4 is arranged between the water inlet chamber and the water outlet chamber, and the recoil chamber 2 is located below the water outlet chamber 3 , a perforated baffle 5 is set between the recoil chamber and the water outlet chamber, one end of the baffle 5 is joined to the lower end of the partition wall 4, and a filter and purification layer is laid on the baffle, and the water inlet chamber 1 and the recoil chamber 2 are integrally connected; a sewage hole 6 is provided at the bottom of the water inlet chamber. The depth of the pool is preferably 1.2-1.5m. The baffle is made of concrete. The area of the baffle is about 4/5 of the pool. The distance between the baffle and the bottom of the pool is about 30cm. The thickness of the baffle is about 5cm. Pave gauze on the baffle. It is advisable that the bottom of the pool is slightly inclined to the sewage outlet to facilitate sewage discharge. The sewage outlet is only opened when cleaning the treatment pool; the water inlet of the water inlet chamber is more than 8cm higher than the overflow. According to the actual situation, clean the filter layer in time. The water flowing into the water inlet chamber passes through the filter purification layer from bottom to top to the water outlet chamber from the recoil chamber to purify the water. Spread 3-4cm biochemical cotton on the baffle plate of the recoil physical filter B, and then densely pile 50cm thick pebbles with a diameter of about 2cm in mesh bags on the biochemical cotton, and then pave about 30cm thick bagged fine sand to It constitutes the filter layer in the recoil physical filter pool B. The baffle in the recoil biological purification tank G is lined with bagged coral sand or other materials with a high adsorption area of 50-60 cm thick to facilitate the attachment of beneficial bacteria and decompose ammonia nitrogen, nitrite and hydrogen sulfide in the water body. The baffle plate in the recoil type activated carbon filter pool H is covered with bagged activated carbon particles with a thickness of 40-50 cm to absorb harmful chemicals such as heavy metals in the water body.

The water in each breeding pond is collected into one flow channel through its outlet and enters the recoil physical filter tank. The residual bait and feces and other large particles visible to the naked eye are removed through the recoil physical filter tank. After further clarification in the sedimentation tank, it is pumped by the water pump. To the water storage buffer pool, it flows through the ozone/ultraviolet disinfection device to kill harmful organisms such as bacteria, viruses, and parasite eggs in the water body. The disinfected water passes through the degassing pool to remove residual ozone, increase dissolved oxygen in the water body, and oxidize part of the organic matter. The harmful substances are decomposed by the recoil biological purification tank, and finally the heavy metal ions and other harmful substances are removed by the recoil activated carbon filter tank, and then flowed back to the breeding pond for recycling. According to the actual situation, a small amount of sterilized external sea water is added to the water supply system every 4 to 7 days to supplement part of the water lost by evaporation.
