Latent heat transpiration odor treatment device and mud biscuitization and odor treatment method

Abstract

The invention discloses a latent heat transpiration stink treatment device which is composed of a wet carburizing reactor, a three-phase latent heat recovery device and a five-stage deodorization device. The invention also discloses a sludge cake drying and stink treatment method by using the treatment device. By using the wet carburizing reactor to treat the sludge, the organic constituents are utilized to generate heat and lower the water content of the sludge; and the three-phase latent heat recovery device is utilized to dry the sludge cake to be treated, so that the water content of the sludge cake can be lowered to 30-40% to 0%. The water content of the treated sludge cake is greatly lowered, thereby maintaining the original nutrients and heat energy and achieving better effects in incineration, land reclamation and composting. The method solves the problem of stink in the sludge drying treatment process, improves the air quality and working environment in the treatment process, and implements the completeness of the sludge treatment technique.

Description

technical field [0001] The invention relates to a combined device for mud biscuitization and odor treatment. [0002] The present invention also relates to a method for mud biscuitization and odor treatment using the above-mentioned device. Background technique [0003] With the continuous improvement of my country's urban sewage treatment rate, the output of urban mud cake has increased sharply. As of 2009, the mud cake output of my country's sewage treatment plants has exceeded 30 million tons. But at present, the effective disposal rate of mud cake in cities nationwide is less than 10%, seriously lagging behind the development of sewage treatment. [0004] Because the mud cake has the characteristics of high moisture content, rich organic matter, strong fluidity, and heavy odor, but in the process of mud cake processing, odor pollution is a prominent environmental problem faced by the industry. The mud cake contains a variety of easily degradable organic matter and abu...
