Description

Self-sinking MABR membrane water treatment system

Technical Field

The utility model belongs to the technical field of the water treatment, concretely relates to from formula MABR membrane water treatment system that sinks.

Background

Aerobic biochemistry is one of the main biochemical techniques for treating wastewater, and can directly decompose organic matters to finally change into water and carbon dioxide. For waste water with low COD, such as polluted river water, the aerobic treatment is the most effective treatment technology for eliminating black and odor and improving water quality. The conventional aerobic biochemical technology needs to provide oxygen to the water body for the metabolism of aerobic bacteria. At present, the mainstream method is to use a high-pressure blower to blow air into water, form relatively small bubbles through an aeration head or an aeration pipe, and then enter a water body, wherein oxygen in the bubbles is dissolved in the water body. The technology has the disadvantages that the blower needs higher pressure and has high operation energy consumption due to the water depth.

The MABR technology adopts non-pressure oxygen supply, has very low operation energy consumption and has very great application prospect. The MABR membrane adopted in the market at present has two forms of a hollow fiber membrane and a flexible flat sheet membrane, and the two forms of membranes are filled with air in the membrane during the operation process, so that the comprehensive density of the membrane unit is less than 1 and the membrane unit floats to the water surface. To prevent floating of the MABR membrane. Generally, an integrated structure is adopted, and an MABR membrane is placed in a stainless steel membrane frame and fixed at the water bottom through the membrane frame. The integration of such integrated structure MABR membranes into a sewage treatment plant is very efficient, since the sewage treatment plant is equipped with circulation and agitation functions inside. However, when the system is applied to water purification of a river channel, the installation and fixation of the bottom of the river channel are inconvenient, and the construction difficulty is large. In addition, since circulation and agitation equipment cannot be provided, the river water and the membrane surface cannot be sufficiently exchanged, and the treatment efficiency is low.
