Abstract

The invention discloses a device for collecting and measuring VSCs gas released by anaerobic stable sludge, which relates to the technical field of biological treatment of sludge. The device comprises a box body system and a gas collecting and measuring system. A first conduit, a second conduit, a third conduit, a fan and a temperature sensing probe are arranged at the top of the box body, one ends of the first conduit, the second conduit and the third conduit are communicated with an inner cavity of the box body, and the other ends are respectively communicated with a gas carrier tank or a Suma tank, a portable high-precision hydrogen sulfide detector and a gas buffer sampling bag. A first valve, a second valve and a third valve are respectively arranged on the first conduit, the second conduit and the third conduit; a sampling port is formed in the bottom of the box body. According to the device for collecting and measuring VSCs gas released by anaerobic stable sludge, the box body system and the gas collection and measurement system are combined, so that the measured discharge rate and discharge amount of the VSCs in the anaerobic stable sludge and the daily change condition are more accurate.

Description

technical field [0001] The invention relates to the technical field of sludge biological treatment, in particular to a device for collecting and measuring VSCs (volatile sulfide) gas released from anaerobic stable sludge. Background technique [0002] With the advancement of my country's urbanization process, my country's urban sewage treatment rate has increased year by year, and the sludge production has also increased sharply. Sludge from urban sewage treatment plants not only has high water content and is perishable, but also has a strong odor. The malodorous gas produced by the sludge will not only cause serious damage to the ecological environment, but also limit the disposal and resource utilization of sludge. At present, the sludge treatment methods of urban sewage treatment plants across the country are different. Only about 10% of the sludge is treated and disposed of through composting and fertilizer technology and then reused on the land, and about 20% of the slu...
