High-efficiency three-phase separator based on up-flow anaerobic reactor

Abstract

The invention provides a high-efficiency three-phase separator based on an up-flow anaerobic reactor. The high-efficiency three-phase separator comprises a separation shell and a separation element, wherein the separation shell can be divided into a reaction area, a three-phase separation area, a gas collection chamber and a settling area from bottom to top; and the separation element is arranged in the three-phase separation area. According to the invention, the sludge loss can be avoided, the sludge precipitation can be accelerated, and the sludge concentration and retention time of the bed layer are ensured, so that the treatment effect of the up-flow anaerobic reactor is improved. By arranging a sufficient number of reflecting covers, firstly, a gas-liquid mixture is separated from sludge particles, and the flow state of rising liquid is shaped into an ordered plug flow mode in the device, so that the sludge can be sufficiently and quickly precipitated. In addition, the height of the gas collection chamber has enough allowance, and the upper part is provided with a defoaming piece, so that a stable gas-liquid interface is formed to realize efficient separation and collection of gas. In a word, the three-phase separator is reasonable in design, the treatment efficiency of the up-flow anaerobic reactor can be remarkably improved, and the three-phase separator has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of wastewater anaerobic treatment, in particular to a high-efficiency three-phase separator based on an upflow anaerobic reactor. Background technique [0002] Anaerobic biological treatment technology is a process in which facultative anaerobic and anaerobic microbial populations convert organic matter into methane and carbon dioxide under anaerobic conditions. Since the treatment process does not require oxygen supply, it can reduce a large amount of system energy consumption, and has the advantages of good COD removal effect, high reaction rate and strong adaptability to toxic substances, so anaerobic reaction is widely used in the water treatment industry. [0003] At present, the most widely used process device is the upflow anaerobic sludge reactor (UASB). Its working principle is to enter the sewage from the bottom of the reactor and pass through the anaerobic sludge bed from bottom to top. Anaerobic...
