specific Embodiment approach 1

[0005] Specific implementation mode one: below in conjunction with attached figure 2 This embodiment will be specifically described. The method for killing chironomus larvae by ultrasonic waves in this embodiment uses ultrasonic waves with a frequency of 147.9 Hz to treat raw water containing chironomus larvae, the ultrasonic power is 120W, and the action time of ultrasonic waves is 5 to 20 minutes. All larvae died within 24 hours.

specific Embodiment approach 2

[0006] Specific implementation mode two: below in conjunction with attached figure 2 This embodiment will be specifically described. The difference between this embodiment and the first embodiment is that the action time of the ultrasonic wave is 5 minutes, and all chironomus larvae in the treated water die within 24 hours. Other steps are the same as those in Embodiment 1. Killing chironomus larvae with a shorter irradiation time can save energy consumption to the greatest extent and reduce costs. This implementation mode is suitable for situations where the requirements for water treatment efficiency are not high.

specific Embodiment approach 3

[0007] Specific implementation mode three: the following in conjunction with the attached figure 2 This embodiment will be specifically described. The difference between this embodiment and Embodiment 1 is that the action time of the ultrasonic waves is 20 minutes, and all chironomus larvae in the water are killed within 8 hours. This embodiment has a higher killing effect. This implementation mode is suitable for situations where high water treatment efficiency is required. Other steps are the same as those in Embodiment 1.

Abstract

The present invention relates to water treatment, and especially supersonic midge larva killing method for water. Unlike available chemical midge larva killing method, which has low killing rate and influences water quality, the present invention treats water containing midge larva with supersonic wave of 147.9 Hz frequency in acting period of 5-20 min and supersonic power of 120 w to kill midge larva completely without generating carcinogenic and mutagenic matters. Compared with other water treating methods, the method of the present invention has the advantages of no generated toxic side matter, operation safety, convenience, low power consumption and low cost, and has also coagulation assisting and algae killing effect.

Description

Technical field: [0001] The invention relates to a water treatment method, in particular to a method for killing chironomus larvae in water by using ultrasonic waves. Background technique: [0002] Ecological deterioration has caused a large number of chironomus larvae in water sources, but it is difficult to effectively remove them by conventional water treatment processes in water plants. The newly hatched chironomus larvae live in planktonic life. They have tenacious vitality, strong anti-oxidation and swimming properties. They can easily penetrate the filter tank and enter the clean water tank to continue to multiply, and then enter the municipal water supply pipe network system. . Chironomus larvae have been found in the clear water pools of water plants and even pipe networks and user water in some large and medium-sized cities in southern my country. The appearance of chironomus larvae in user water not only violates the national regulations on sensory traits in dri...
