【摘要】： 寄生蟲病長(zhǎng)期危害人們身體健康,嚴(yán)重影響了經(jīng)濟(jì)的發(fā)展,制約著人們生活水平的進(jìn)一步提高。因此,寄生蟲病的防治具有重大的社會(huì)意義。殺滅寄主排泄出的寄生蟲卵,切斷感染源,破壞其生命周期,是降低寄生蟲感染率的最有力的方法。 常用的寄生蟲病感染源藥物處理方法存在易產(chǎn)生抗藥性、污染環(huán)境、毒殺其他生物等弊端,改善衛(wèi)生條件措施存在投資大,推進(jìn)速度慢等缺點(diǎn)。針對(duì)現(xiàn)有措施的不足,本文提出了一種利用高壓脈沖電場(chǎng)技術(shù)殺滅寄生蟲卵的新方法,研究了該方法的可行性,介紹了蛔蟲卵生物膜結(jié)構(gòu)的模型,探討了豬蛔蟲卵高壓脈沖電場(chǎng)殺滅機(jī)理,設(shè)計(jì)了高壓脈沖電源,研制了實(shí)驗(yàn)室寄生蟲卵殺滅裝置,進(jìn)行了豬蛔蟲卵高壓脈沖電場(chǎng)殺滅試驗(yàn)。 本文共分為六章： 第一章描述了常見寄生蟲病的危害,介紹了高壓脈沖電場(chǎng)技術(shù)現(xiàn)狀和發(fā)展趨勢(shì),說明了高壓脈沖電場(chǎng)技術(shù)應(yīng)用于寄生蟲卵殺滅的重大意義,指出了本文的研究背景和主要內(nèi)容。 第二章介紹了豬蛔蟲卵的結(jié)構(gòu),探討了豬蛔蟲卵的介電模型,研究了豬蛔蟲卵高壓脈沖電場(chǎng)殺滅技術(shù)機(jī)理。 第三章主要介紹了高壓脈沖發(fā)生器原理,設(shè)計(jì)了基于電力電子開關(guān)器件的高壓脈沖電源。 第四章介紹了高壓脈沖電場(chǎng)試驗(yàn)裝置結(jié)構(gòu),設(shè)計(jì)了四種處理電極形式,分析氣液兩相時(shí)電場(chǎng)分布和電壓擊穿隨機(jī)過程,討論了試驗(yàn)安全性防護(hù)措施。 第五章介紹豬蛔蟲卵殺滅試驗(yàn)設(shè)計(jì),描述了豬蛔蟲卵殺滅試驗(yàn)過程,分析了試驗(yàn)數(shù)據(jù)和實(shí)驗(yàn)現(xiàn)象。 最后結(jié)論部分總結(jié)了本文的創(chuàng)新和不足。 寄生蟲卵高壓脈沖電場(chǎng)殺滅方法避免了現(xiàn)有寄生蟲病防治方法的不足,還具有污水降解,殺菌等功效,具有積極的社會(huì)意義和廣闊的應(yīng)用前景,為進(jìn)一步降低寄生蟲病感染率提供了一種綠色的的嶄新途徑。
[Abstract]:Parasitosis has been harmful to people's health for a long time, has seriously affected the development of economy and restricted the further improvement of people's living standard. Therefore, the prevention and treatment of parasitic diseases has great social significance. Cutting off the source of infection and destroying its life cycle is the most powerful way to reduce the infection rate of parasites. The commonly used drug treatment methods for parasitic infection sources have disadvantages such as easy to produce drug resistance, pollute the environment, poison and kill other living things. The measures to improve sanitary conditions have disadvantages such as large investment, slow speed of advance, etc. In view of the shortcomings of the existing measures, In this paper, a new method of killing parasite eggs by using high voltage pulsed electric field is proposed. The feasibility of this method is studied. The model of biofilm structure of Ascaris lumbricoides eggs is introduced, and the mechanism of killing parasite eggs by high voltage pulsed electric field is discussed. The high voltage pulse power supply was designed, the laboratory parasite egg killing device was developed, and the experiment of killing the eggs of Ascaris suis by high voltage pulse electric field was carried out. This paper is divided into six chapters:. The first chapter describes the harm of common parasitic diseases, introduces the current situation and development trend of high-voltage pulsed electric field technology, and explains the great significance of the application of high-voltage pulsed electric field technology in the killing of parasite eggs. The research background and main contents of this paper are pointed out. In chapter 2, the structure of Ascaris lumbricoides eggs is introduced, the dielectric model of Ascaris lumbricoides eggs is discussed, and the mechanism of high voltage pulsed electric field killing of Ascaris lumbricoides eggs is studied. In chapter 3, the principle of high voltage pulse generator is introduced, and the high voltage pulse power supply based on power electronic switch device is designed. In chapter 4th, the structure of high voltage pulsed electric field test device is introduced, four kinds of treatment electrodes are designed, the electric field distribution and the random process of voltage breakdown in gas-liquid two-phase are analyzed, and the safety protection measures are discussed. Chapter 5th introduces the design of ascaris lumbricoides eggs killing test, describes the process of ascaris suum eggs killing test, analyzes the experimental data and experimental phenomena. Finally, the conclusion summarizes the innovation and deficiency of this paper. The method of killing parasite eggs with high voltage pulse electric field avoids the deficiency of existing methods of preventing and treating parasitic diseases, and has the functions of sewage degradation, sterilization and so on. It has positive social significance and broad application prospect. It provides a new green way to reduce the infection rate of parasitic diseases.
