Textile bleaching and dyeing sewage treatment device

Abstract

The invention discloses a textile bleaching and dyeing sewage treatment device. The textile bleaching and dyeing sewage treatment device comprises a main box body, a sewage inlet pipe, a drain pipe, ablow-off pipe, a filter element, an ultraviolet sterilizing lamp, an active carbon bag, a filter screen board and a vertical baffle plate, wherein the vertical baffle plate is arranged at the lower end inside the main box body; the filter screen board is arranged at the upper end of the vertical baffle plate; the inside of the main box body is partitioned into two cavities through the vertical baffle plate and the filter screen board. Textile bleaching and dyeing sewage is filtered by three times with the filter element, the active carbon bag and the filter screen board arranged in the main box body, so that harmful substances in the textile bleaching and dyeing sewage can be reduced effectively; the ultraviolet sterilizing lamp is provided for sterilizing the textile bleaching and dyeingsewage, so that bacteria breeding is reduced. Compared with the prior art, the textile bleaching and dyeing sewage treatment device has the advantages that most water can be recycled in production, so that the wastewater discharge can be reduced, the resource is saved, and the environment is protected. Meanwhile, the textile bleaching and dyeing sewage treatment device has the advantages of low investment cost, low energy consumption, high treatment efficiency and the like.

Problems solved by technology

[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.
