Anti-clogging textile bleaching and dyeing sewage treatment plant

Abstract

The invention discloses an anti-clogging textile bleaching and dyeing sewage treatment plant, which comprises a main box, a sewage inlet pipe, a drainpipe, a second box, an ultraviolet germicidal lamp, a first filter screen plate, a second filter screen plate, a vertical baffle plate, a first silk thread grabbing device and a second silk thread grabbing device. Through the silk thread grabbing devices for grabbing silk threads and fibers in textile bleaching and dyeing sewage, silk threads and fibers are prevented from blocking the sewage treatment plant. by arranging the first filter screen plate, the second filter screen plate and a filter core inside the main box to filter the textile bleaching and dyeing sewage for three times, harmful substances in the textile bleaching and dyeing sewage can be effectively reduced. Through the arrangement of the ultraviolet germicidal lamp for sterilizing the textile bleaching and dyeing sewage, breeding of bacteria is reduced. In comparison withthe traditional technologies, the invention has the following beneficial effects: most water meets requirements of industrial reuse, discharge of wastewater can be reduced, resources are saved, and the environment is protected; and the anti-clogging textile bleaching and dyeing sewage treatment plant has advantages of low investment cost, low energy consumption, high treatment efficiency and the like.

[0002] In order to prevent the deterioration of the natural environment and protect the green mountains, green water, blue sky and sea, people pay more and more attention to environmental protection issues. At present, tens of thousands of dyes are used in the world, and dyeing wastewater mainly contains dyes and pulp , additives, oil agents, acids and bases, fiber impurities and inorganic salts, etc., have the characteristics of complex composition, multiple changes, high concentration, high chroma, strong toxicity, refractory degradation, and wide range of water quality fluctuations. It is the main organic wastewater in my country. One of the sources of pollution, with the development of the textile bleaching and dyeing industry, there are more and more problems in the treatment of wastewater produced by bleaching and dyeing. Traditional processing methods still have a large amount of chemical agents used, high processing costs, large land occupation, complex processes, and investment. Therefore, it is very urgent to find a new type of washing, bleaching and dyeing sewage treatment device with mature technology to replace the traditional treatment process. The sewage produced by textile bleaching and dyeing also contains a large amount of silk and Fibrous matter, traditional sewage treatment devices are easily blocked by silk threads and fibrous matter, which affects the efficiency of sewage treatment
