Abstract
The invention discloses a bioreactor for online automatic pH control. The bioreactor comprises a data acquisition controller, an alkali storage tank, an acid storage tank, a regulation tank and a biological reaction tank, wherein the data acquisition controller comprises a pH acquisition unit, a liquid level acquisition unit and an electromagnetic valve which are connected with a peristaltic pump control unit; the alkali storage tank and the acid storage tank are connected with the regulation tank and the biological reaction tank through a pipeline with an electromagnetic valve; a liquid inlet of the regulation tank is connected with the biological reaction tank through a pipeline with a peristaltic pump, and a liquid outlet is connected with the biological reaction tank through the pipeline with an electromagnetic valve; the regulation tank is provided with a pH meter and a liquid level meter; the biological reaction tank is provided with a gas outlet, a stirrer and a liquid level meter; the pH meter is connected with the pH acquisition unit; the liquid level meter is connected with the liquid level acquisition unit; the electromagnetic valve and the peristaltic pump are connected with the electromagnetic valve and the peristaltic pump control unit. The bioreactor disclosed by the invention can effectively realize online control on the pH in the reactor in real time so as to avoid local impact of high-concentration acid-base reagent on microbial activity and promote long-term efficient and stable operation of the reactor.
