Control method for treating sulfur-containing and nitrogen-containing wastewater by using sleeve-type phase-separation anaerobic reactor for organic wastewater treatment

Abstract

A sleeve-type phase-separation anaerobic reactor for organic wastewater treatment and a control method for treating sulfur-containing and nitrogen-containing wastewater. The present invention relates to an anaerobic reactor for treating organic wastewater and its application method. The first-stage anaerobic reactor equipment occupies a large area and the pipeline connection is complicated. The sleeve-type phase-splitting anaerobic reactor includes an inner cylinder, an outer cylinder, a water distribution device and two three-phase separation devices. The inner cylinder and the outer cylinder are coaxially arranged, and a water distribution device is installed at the bottom of the inner cylinder. The upper part of the cylinder is equipped with a three-phase separation device, and a water outlet is opened on the wall of the inner cylinder. The coffering weir and the outer wall of the inner cylinder form a sedimentation area, and a plurality of downpipes are fixed on the bottom plate of the cofferdam. Extends to the bottom of the outer cylinder. The sleeve-type two-stage anaerobic reactor of the present invention is closely arranged, occupies a small area, and is simple in management and control, and realizes the two-stage biochemical treatment process of hydrolytic acidification and anaerobic methane production of waste water in one reactor, and improves the water output. water quality.

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...
