VT-MBR (Vertical Tubular-Membrane Bioreactor)

Abstract

The invention discloses a VT-MBR (Vertical Tubular-Membrane Bioreactor), which consists of a VTBR (Vertical Tubular Biochemical Reactor) device, a membrane separating device, a buffer pool, a circulating pump and an exhaust port, wherein feed water and an air source enter the VTBR device consisting of multiple stages of VTBR reaction columns through a jet mixing device; the tail end of the VTBR device is connected with the membrane separating device; a residual liquid in the membrane separating device enters the buffer pool, and is circulated to the VTBR device through the circulating pump; tail gas in the membrane separating device is exhausted through the exhaust port on the upper part of the buffer pool; the membrane separating device is formed by connecting a tubular membrane assemblyin series; pressure gauges are connected above and below the membrane assembly; membrane filtering power is provided by a residual pressure on the tail part of the VTBR device; water discharge is controlled by regulating a pressure with a pressure regulating valve; the tubular membrane assembly consists of a series of membrane bundles, and is sealed through epoxy resin; and a gas-liquid mixing and shunting device is arranged at the bottom of the tubular membrane assembly. Due to the adoption of the VT-MBR, the biodegradability of the VTBR device is strengthened, the treatment load is raised, the membrane pollution capacity is controlled effectively simultaneously, and a membrane pollution period is prolonged.

Description

technical field [0001] The invention relates to a wastewater treatment technology, in particular to a VT-MBR bioreactor. Background technique [0002] With the rapid development of my country's economy and the acceleration of urbanization, my country's industrial water use and residential water use have increased significantly, and the discharge of industrial wastewater and domestic sewage has aggravated the situation of resource water shortage and water quality water shortage in my country. Sewage treatment technology can not only solve the problem of water pollution and environment, but also an important way to solve the problem of water shortage. Among them, biological sewage treatment technology has a history of nearly a hundred years, but the pursuit of higher treatment effect and lower operating cost has always been the goal pursued by people. [0003] The vertical baffle biochemical reactor (VTBR) technology was invented based on the principle of deep well aeration. ...

Problems solved by technology

However, in the process of membrane filtration, due to the problem of membrane fouling, the operating cost of the reactor increases and the benefit decreases

Studies have shown that aeration can form a gas-liquid two-phase flow on the membrane surface and increase the shear force on the membrane surface, which can effectively control the membrane fouling behavior, but the increase in aeration may increase the energy consumption of the reactor, thereby increasing the cost
