Novel anaerobic reactor

Abstract

The invention provides a novel anaerobic reactor which comprises a rack, a reaction mechanism is mounted at the top of the rack, the reaction mechanism comprises a reaction tank, a bottom tank is riveted to the bottom of the reaction tank, and an emptying valve is inserted into the bottom of the bottom tank. According to the invention, an intelligent pH meter with modbus communication, a COD online detector and a temperature sensor are used, and a regulating valve with an adjustable opening degree and a related water pump with frequency conversion control are combined to communicate with a self-developed intelligent water affair cloud platform, so that data are uniformly transmitted to a database; real-time changes of pH, temperature, COD and other signals in the anaerobic reactor are predicted and analyzed through an artificial intelligence optimization control model, the production efficiency is improved, and the power consumption is reduced; and through data prediction, the probability of failure of the anaerobic process section is greatly reduced, and an intelligent production mode of unattended operation or few-person operation of the anaerobic process section is realized.

Description

technical field [0001] The invention relates to the technical field of anaerobic reactors, in particular to a novel anaerobic reactor. Background technique [0002] Anaerobic biological treatment refers to the process of decomposing organic matter to produce CH4 and CO2 under anaerobic conditions by the joint action of various microorganisms (anaerobic or facultative) microorganisms. There are three stages in the anaerobic treatment process, which are the hydrolytic acidification stage, the hydrogen production stage and the methane production stage. The commonly used anaerobic reactors mainly include upflow anaerobic sludge bed, anaerobic expanded bed, and internal circulation. Anaerobic reactors, etc. Let's take typical examples such as upflow anaerobic sludge bed and internal circulation anaerobic reactor: 1. The upflow UASB anaerobic reactor uses a variety of anaerobic bacteria to carry out all anaerobic reaction processes such as hydrolysis acidification, acid product...

AI Technical Summary

Problems solved by technology

1. Both adopt the form of bottom water inlet and upper water outlet. The reactor contains a large amount of anaerobic sludge. After a long time of operation, the sludge will settle. After the sludge settles, the lower water distributor will be blocked. After the blockage, it is very difficult to clean it. Troublesome and affects the water inlet efficiency of the entire reactor

[0005] 2. Gas-water separation needs to install a three-phase separator on the top of the reactor. The three-phase separator is used to separate the sludge, water and the generated biogas. The three-phase separator is located at the top of the reactor where the gas and water are in contact with each other. In general, this part is most prone to corrosion, so the life of the separator is limited, and when a problem occurs, it will affect the use and reduce the processing efficiency

[0006] 3. The existing process will generate sludge during the reaction process. The amount of sludge in the reactor is a stable amount. As time goes by, the sludge will increase. At this time, the excess sludge needs to be removed For external discharge, since the sludge is a hazardous waste, it will not only cause harm to the environment but also cause high treatment costs

[0007] 4. The reaction environment of the reaction tank is closely related to the sewage data. The temperature and pH value of the sewage have a great influence on the reaction efficiency of microorganisms in the reaction tank. However, the existing reaction system cannot collect and record sewage information. Manual collection is not only intensive, but also And the efficiency is low. At the same time, the existing system cannot control the environment in the reaction tank, the efficiency of sewage treatment is low, and automation and intelligent control cannot be achieved.
