Abstract

The invention relates to a coiled tube type sludge sampling and activity evaluation device for an anaerobic reactor and a working method thereof. The device comprises a coiled tube sampling system, asludge testing system and a PLC control system. The coil sampling system comprises the anaerobic reactor, a stainless steel hose, a support frame and a positive and negative constant-speed coil-metering pump. The sludge testing system comprises a densimeter, a pH/T tester, a storage reaction tank with a stirrer, a pressure gauge, a methane/carbon dioxide concentration tester, a methane emptying pipe with a control valve, a metering pump and a detection liquid storage tank. The PLC control system includes a PLC central controller. The whole sampling period comprises two times of full-height sampling of the anaerobic reactor from bottom to top and from top to bottom, thus ensuring the representativeness, comprehensiveness and data accuracy of the sampled sludge.

Description

Technical field: [0001] The invention relates to a coiled tube sludge sampling and activity evaluation device for an anaerobic reactor and a working method thereof, belonging to the field of special equipment for anaerobic treatment of high-concentration sewage in environmental protection engineering. Background technique: [0002] The anaerobic reactor has the characteristics of small footprint, high processing load, low operating cost and energy recovery; it has always occupied an extremely important and core position in the treatment of high-concentration wastewater. Under the guidance of the national policy of energy conservation and emission reduction, the design and construction of anaerobic reactors are showing a gradual upward trend. At present, the most common anaerobic reactors for high-concentration wastewater in China mainly include UASB, EGSB, and IC reactors. The properties and activity of the anaerobic sludge filled in the reactors directly determine the opera...
