The invention relates to an anaerobic tank heating system. The anaerobic tank heating system comprises an anaerobic tank body, an outer hot water source, a water inlet pipe, a heating pipeline and a water outlet pipe, wherein the heating pipeline is arranged inside the anaerobic tank body, two ends of the heating pipeline are respectively connected with the water inlet pipe and the water outlet pipe, the water inlet pipe and the water outlet pipe respectively extend out of the anaerobic tank body, the periphery of the outer wall of the water inlet pipe and the water outlet pipe is connected with the anaerobic tank body in a sealing manner, and one end, away from the anaerobic tank, of the water inlet pipe is connected with the outer hot water source. The residual hot water in the production is continuously conveyed to the heating pipeline in the anaerobic tank body, waste water in the anaerobic tank body exchanges the hot water flowing in the heating pipeline, so that the temperature of the waste water in the anaerobic tank can rapidly increase to 30 to 38 DEG C from below 20 DEG C, and the heating time is reduced by 70 to 90 percent compared with the traditional heating way; and the sludge activity of the anaerobic bacteria can be rapidly restored, the capability of the anaerobic tank for treating the waste water can be restored, and the stable operation in the production canbe ensured.
Description
technical field [0001] The invention relates to the technical field of sewage treatment anaerobic tank equipment, in particular to an anaerobic tank heating system and a rapid and stable heating method. Background technique [0002] With the serious situation of domestic environmental protection, industrial wastewater treatment has attracted more and more attention from the society. Especially in winter, when the temperature drops, the anaerobic system will face the problem of starting and stopping at any time. In the past, when the anaerobic tank was shut down and restarted in winter, due to temperature constraints, it was necessary to gradually increase the temperature inside the anaerobic tank through external heating to restore the activity of anaerobic bacteria. However, the external heating will cause the temperature to rise unevenly and slowly; this will prolong the anaerobic start-up time, affect the production operation, and limit the treatment capacity and treatme...
