Device and method for temperature-controlled aerobic-anaerobic coupled biological hydrogen production

Abstract

A device for temperature-controlled aerobic-anaerobic coupled biological hydrogen production comprises a fermentation tank which is installed on a base, wherein the base is provided with a universal wheel which can rotate for 36 degrees and a wheel lock; one side of a fermentation tank body is provided with a feed port, and the other side of the fermentation tank body is provided with a discharge port; the inner part of the fermentation tank is a double-reaction area structure which consists of an aerobic pretreatment chamber and a fermentation hydrogen production chamber, and valves which can be opened from one direction are respectively arranged in the middles of the aerobic pretreatment chamber and the fermentation hydrogen production chamber; a baffle is installed at the inner wall of the fermentation tank; the fermentation tank body is of a double-layer structure, namely two independent interlayers wrapping the aerobic pretreatment chamber and the fermentation hydrogen production chamber; heat transfer liquid is filled in interlayers; the two interlayers are respectively provided with a liquid inlet valve and a liquid discharge valve, and connected by pipelines to form a temperature control layer; and a nanophase ceramic membrane roller penetrates through the center of the tank body, and the gas outlet of the nanophase ceramic membrane roller is connected with a gas collection device. The invention further discloses a method for biological hydrogen production utilizing the device.

Description

technical field [0001] The invention belongs to the technical field of biological energy, and in particular relates to a non-powered good temperature control-anaerobic coupled biological hydrogen production device. [0002] The present invention also relates to a method for biological hydrogen production using the hydrogen production device. Background technique [0003] The increasing depletion of global non-renewable energy and environmental pollution pose a serious threat to human survival and sustainable development. The development of clean energy with high added value has become a research hotspot. As an efficient, clean and renewable energy, hydrogen has attracted increasing attention. [0004] With the advancement of the construction of a new socialist countryside, while the living standards of villagers have improved, it has also brought about environmental pollution and waste of resources in villages and towns. According to reports, my country is the country with...
