Abstract: To strengthen enviromental governance，it is necessary to comb the fine dust control technology，providing a technological clue and research basis for further study. Combining the latest document of fine particles control technology at home and abroad，backtracks the routine dedusting technology，combs the research achievement of fine particle coagulation removal theory and technology，focuses on technological feature of electric coagulation technology，acoustic coagulation technology，vapor condensation technology，meanwhile，analyses and concludes the other coagulation tech? nology such as thermal coagulation，chemical coagulation，magnetic coagulation，turbulent coagulation，and light coagulation. On the basis of comprehensis analysis of these technology，points out the development trend of fine particle control technology，aiming to provide references to researchers.

Key words: fine dust, dedusting technology, coagulation technology, electric coagulation technology
