Abstract

The invention discloses a biological treatment system of sludge odor and a method for treating the sludge odor by utilizing the same, relating to the field of solid waste treatment. The biological treatment system of the sludge odor comprises an odor collector, an odor fan, an intake pipe, a biological deodorization tower, an outlet pipe, an active carbon adsorption device, a gas monitor and a discharge pipe. The method for treating the sludge odor by utilizing the biological treatment system comprises the following steps of: (1) injecting a bacterial solution enriched with thiobacillus denitrificans and nitrobacteria, acclimatizing for three weeks to finish starting; and (2) charging odor into the biological treatment system for treating through the odor fan. According to the biological treatment system of the sludge odor and the method for treating the sludge odor by utilizing the same, disclosed by the invention, main components of the sludge odor are removed by utilizing thiobacillus denitrificans and nitrobacteria, soft-hard bilayer fillers are adopted and active carbon is adopted for the following adsorption, thus the treatment effect is ensured; in addition, the biological treatment system of the sludge odor and the method for treating the sludge odor by utilizing the same, disclosed by the invention, have the advantages of low energy consumption and operation cost, and high safety and reliability, and is suitable for odor treatment of a large / middle sludge treatment project.

Description

technical field [0001] The invention relates to the field of solid waste treatment. Background technique [0002] With the acceleration of social development and urbanization, the construction of sewage treatment plants has increased, and the output of sludge has also increased rapidly. The treatment and disposal of sludge has become a new focus in comprehensive environmental management. Because the sludge emits odor, it will have adverse effects on the surrounding environment and operators during the process of sludge treatment and disposal, so the odor generated by the sludge should be collected and treated. The main components of sludge odor are inorganic substances such as hydrogen sulfide and ammonia, and methyl mercaptan, methylamine, methyl sulfide, etc. Among the components, hydrogen sulfide and ammonia have the highest concentrations. [0003] Deodorization technology developed relatively early in foreign countries and has a wide range of applications. In China, i...
