Embodiment Construction

[0010] As shown in the drawings, the spiral self-circulating anaerobic bioreactor has a reactor body, which has a reactor body and a support 20. The reactor body is divided into a plug flow reaction chamber 1, a gas collection chamber 2 and a gas chamber from bottom to top. The liquid separation chamber 3; the plug flow reaction chamber 1 is connected with the gas collection chamber 2 through the outer cylindrical expanding pipe 10, and the mud discharge pipe 4 and the water inlet pipe 5 are arranged at the lower end of the plug flow reaction chamber 1, and the plug flow reaction The chamber 1 is provided with a spiral plate 6 and a return pipe 8. The lower end of the return pipe 8 is connected to the bottom of the reaction chamber, and the upper end is connected with the center of the three-phase separator 14 and the center of the reducer 12; The three-phase separator 14 communicates with the settling chamber 13 through the sludge return slot 9 below the gas collecting hood 11...

Abstract

The invention discloses a spiral type self loop anaerobic organisms reactor. It has the identity and support for the reactor. The reactor includes plug flow reaction chamber, common air chamber and gas liquid separation. The plug flow reaction chamber connects to common air chamber by excircle tube flaring pipe. The bottom of plug flow reaction chamber has discharge pipeline and influent pipe. The spiral lamina and back flow are set in plug flow reaction chamber. The bottom of back flow connects to the bottom of reaction chamber. Superior end connects with the center of three phase separator reducing pipe. The return-sludge flow sew of the bottom of three phase separator connects to settling chamber. The turbid water lifting pipe and back flow are fixed on the flaring pipe back flow board of three phase separator. The invention could effectively denial short current and air emerging phenomenon, intensify ground substance degradation. It ensures the high efficiency and stable of the running feature of reactor.

Description

technical field [0001] The invention relates to a spiral self-circulation anaerobic bioreactor. Background technique [0002] Anaerobic biological treatment technology is the process of converting organic pollutants into biogas by using the metabolism of microorganisms under anaerobic conditions, so as to purify sewage. Compared with aerobic biological treatment, anaerobic biological treatment has the characteristics of low energy consumption, low sludge output, and the ability to recover clean energy (biogas). It is one of the effective means to realize circular economy and has broad application prospects. [0003] With the deepening of people's understanding of anaerobic biological processes and the popularization of the application of anaerobic biological treatment technology, anaerobic bioreactors have also been better developed. So far, anaerobic bioreactors have been developed to the third generation of high-efficiency reactors represented by anaerobic granular sludge...
