Sleeve type split-phase anaerobic reactor for organic wastewater treatment as well as regulating and controlling method for treating sulfur-containing and nitrogen-containing wastewater by using reactor

Abstract

The invention relates to an anaerobic reactor for treating organic wastewater and an application method, particularly to a sleeve type split-phase anaerobic reactor for organic wastewater treatment as well as a regulating and controlling method for treating sulfur-containing and nitrogen-containing wastewater by using the reactor, and aims to solve problems that existing two-stage anaerobic reactor equipment occupies large areas and pipeline connection is complex. The sleeve type split-phase anaerobic reactor comprises an inner barrel, an outer barrel, a water distribution device and two three-phase separation devices, wherein the inner barrel and the outer barrel are arranged coaxially, the water distribution device is mounted at the bottom of the inner barrel, one three-phase separation device is arranged at the upper part of the inner barrel, a water outlet is formed in the wall of the inner barrel, a settling zone is defined by a cofferdam and the outer wall of the inner barrel, and multiple downcomers are fixed on a bottom plate of the cofferdam and extend to the bottom of the outer barrel. The sleeve type two-stage anaerobic reactor is closely arranged, occupies a small area and is simple to manage and control, the two-stage biochemical treatment process of hydrolytic acidification and anaerobic methane production of the wastewater is finished in one reactor, and the quality of effluent is improved.

Description

technical field [0001] The invention relates to a novel anaerobic reactor for treating organic waste water and a control method for treating sulfur-containing and nitrogen-containing organic waste water using the same. Background technique [0002] Anaerobic biological treatment of high-concentration organic wastewater will undergo reaction processes such as hydrolytic acidification and methane production. Acidogenic bacteria and methanogenic bacteria are quite different in terms of nutritional requirements, growth rate and sensitivity to environmental conditions, and their ecological niches are also very different. In a single-phase anaerobic reactor, it is difficult to achieve a coordinated balance between the two types of flora. The two-phase anaerobic treatment process separates the two stages of hydrolytic acidification and methanation into two series reaction units, so that acid-producing bacteria and methanogenic bacteria can grow under their respective optimal envir...
