Sewage treatment anaerobic reactor with scum and crusting eliminating function

Abstract

The invention discloses a sewage treatment anaerobic reactor with a scum and crusting eliminating function, the reactor comprises a reactor body, the lower part of the reactor body is provided with a water inlet and a sludge outlet, and a lower-layer three-phase separator and an upper-layer three-phase separator are sequentially fixed in the inner cavity of the reactor body from bottom to top. An overflow weir is fixed on the upper-layer three-phase separator in the inner cavity of the reactor body, and a water outlet is formed in the overflow weir. The lower-layer three-phase separator and the upper-layer three-phase separator are both communicated with an exhaust pipe, the exhaust pipe is connected with a liquid seal device fixed on the top surface of the reactor body, and the liquid seal device is connected with a biogas cabinet outside the reactor body. A pneumatic shell breaking mechanism is fixed between the upper-layer three-phase separator and the overflow weir, is provided with a plurality of upward air nozzles, and is connected with the biogas cabinet through a pressure pump. The reactor not only can utilize the generated biogas to break scum or crusts at the upper part of the reactor, but also has the characteristic of improving the solid-liquid separation effect.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an anaerobic reactor for sewage treatment with the function of eliminating scum and encrustation. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] In terms of industrial wastewater treatment, the pollutants in some chemical industry and chemical industrial park wastewater have complex components, such as benzene compounds, pyridine compounds, refractory polymers, etc. At the same time, wastewater often contains a large amount of salt, resulting in poor biodegradability of wastewater. Therefore, this type of sewage is subjected to anaerobic biological trea...

Problems solved by technology

[0004] However, because the sewage needs to stay in the anaerobic reactor for a long time, as the reaction proceeds, it is easy to form scum on the liquid surface of the sewage, and even form crusts in severe cases, which will hinder the treated sewage, Biogas Emissions
