Problems solved by technology

The fermentation of activated sludge is a key link. High-temperature fermentation can also achieve the purpose of sterilization and disinfection. However, during the process of fermentation and sludge stacking, unpleasant gases will be produced, especially in anaerobic fermentation when the water content is high. The smell is e

Example Embodiment

[0014] The following describes the present invention in more detail through specific embodiments:

[0015] Reference figure 1 , Activated sludge fermentation gas continuous cleaning and deodorization method, including spray washing liquid and gas washing device, 100 kg of tap water for the liquid, 4 kg of sodium chlorite, and then a small amount of liquid potassium hydroxide , Add the amount of liquid potassium hydroxide to adjust the PH value of the liquid to 8.8, then add 0.4 kg of active zinc oxide, and the above components are evenly mixed to become the spray liquid; figure 1 As shown, a vertical cylindrical scrubber (2) is manufactured. An exhaust fan (1) is installed next to the tower. The inlet of the exhaust fan (1) is connected with the gas produced by the activated sludge fermentation field. (1) The outlet is connected to the lower part of the scrubbing tower (2). The scrubbing tower (2) is equipped with a distribution screen (3), a liquid spray pipe (5), a liquid remo...

Abstract

The invention discloses a continuous clean deodorizing method for activated sludge fermentation gas, which pumps gas generated by the fermentation of the activated sludge into a liquid medicine washing tower by an exhaust fan, by using the liquid medicine for spray washing, emptying is realized after fermentation smell is removed, and the liquid medicine is circularly used by a pump, thus solvingthe problem that the activated sludge fermentation gas needs the continuous clean deodorizing, having the advantages of simple equipment, easy operation, and continuous, fast and clean removing odor generated by the fermentation of the activated sludge and the like, and being widely applied to deodorizing of the activated sludge.

Description

technical field [0001] The invention relates to a method for deodorizing fermented gas, in particular to a method for continuously cleaning and deodorizing activated sludge fermented gas. Background technique [0002] At present, my country's sewage treatment plants are generally built throughout the country. The by-products of sewage plants, the amount of activated sludge has increased sharply, reaching tens of millions of tons per year in the country. The harmlessness and resource utilization of activated sludge has become an urgent need. Major issues to be solved; at present, the disposal of activated sludge is mainly landfill, which is prone to secondary pollution, followed by incineration or agricultural use. A better solution should be fermentation in solar sheds, dehydration and drying at the same time, so that the water content of activated sludge Reduce from 75 to 82% to about 20%, and then go to incineration or agricultural use or landfill, so as to achieve the goals...
