Problems solved by technology

At present, the treatment methods for jellyfish outbreaks mainly include manual salvage, mechanical crushing, etc. These treatment methods are all treatment measures after the catastrophic emergence of jellyfish, and the losses caused to people's production and life are inevitable.

Embodiment 1

[0025] Depend on figure 1 As shown, the device includes a treatment device, a corrugated plate with a polyp attached, an ultrasonic vibrating plate and an ultrasonic device; the processing device is inserted with at least one corrugated plate with a polyp attached and an ultrasonic vibrating plate, and the ultrasonic vibrating plate communicates with the ultrasonic device through a wire connect.

[0026] The corrugated plate attached to the polyp body is detachably arranged on the opposite side and the bottom of the ultrasonic vibrating plate; wherein, the dish-shaped body or jellyfish body lives for swimming, and the dish-shaped body or jellyfish body to be treated is placed in the reactor, which can float processed in the reactor.

Embodiment 2

[0028] (1) Get 4 groups of corrugated plates attached to the hydra of the sea jellyfish, and each group has 3 repetitions. Set up the control group (do not accept ultrasonic treatment), the 20KHZ frequency treatment group, the 28KHZ frequency treatment group, and the 40KHZ frequency treatment group. body is processed. When processing, the corrugated plate is placed on the opposite side and bottom of the ultrasonic vibrating plate ( figure 1 ), processed once a day, each processing time is 20min. After the treatment, the corrugated plate attached with the polyps of the jellyfish was disassembled and put back into the original incubator to continue culturing. During the treatment period, feed normally and change water. Respectively record the reduction rate (see Fig. 2) of polyps on the corrugated plate that is attached to the jellyfish polyp body after each treatment; Reduction rate=(initial polyp body density a 0 - polyp density a per day after treatment n ) / initial polyp ...

Embodiment 3

[0037] (1) Get 4 groups of corrugated plates attached to the polyps of the jellyfish, each group has 3 repetitions, and in each repetition, the corrugated plates are placed on the opposite side and bottom of the ultrasonic vibrating plate ( figure 1 ). Ultrasonic treatment with 28KHZ frequency, the treatment time is 0min (control group), 20min, 40min, 60min respectively, once a day, during the treatment period, normal feeding and water change. Record the polyp density a of each group of corrugated plates after n days of treatment n , and calculate the reduction rate of the polyp (see Figure 5); reduction rate=(initial polyp density a 0 - polyp density a per day after treatment n ) / initial polyp density a 0 , n is the number of treatment days.

[0038] (2) Take 4 groups of moon jellyfish disks with similar size and good condition, each set up 3 replicates, each replicate 100 disks, and place them in 12 treatment reactors of appropriate size for culture ( figure 1 ). Ultra...

Abstract

The invention belongs to the field of ocean ecological disaster treatment application, and particularly relates to a method for removing jellyfishes in seawater through ultrasonic. A to-be-treated water body is arranged in the ultrasonic environment, jellyfish individuals in the water body in different life history stages are fragmented through the cavitation effect of the ultrasonic till jellyfishes in the body are removed; the release frequency of the ultrasonic is 20 KHZ to 40 KHZ, jellyfishes are subjected to ultrasonic for 20 min to 60 min every time and are subjected to ultrasonic one time. The method is easy and convenient to operate and remarkable in effect, and has good application prospects for controlling ocean ecological problems such as jellyfish blooming in an ocean.

Description

technical field [0001] The invention belongs to the application field of marine ecological disaster treatment, and in particular relates to a method for removing jellyfish in seawater by ultrasonic waves. Background technique [0002] In recent years, outbreaks of jellyfish (mainly moon jellyfish) in China's coastal waters have become increasingly frequent, causing great damage to the marine ecological environment. The outbreak of jellyfish has seriously damaged marine fishery resources and reduced catches; destroyed the beautiful scenery of the coastal area, forced to close some tourist facilities, and even endangered the health of tourists, greatly affecting the coastal tourism industry; sailing ships cannot operate normally ; The cooling water outlets of coastal large-scale industries (such as nuclear power plants, etc.) are blocked, so they are forced to stop working, which brings a lot of inconvenience to the production and life of residents, and even causes major econo...
