Description

Technical Field

[0001] This utility model relates to the field of integrated MBR device technology, and in particular to an integrated MBR device. Background Technology

[0002] Integrated MBR (Membrane Bioreactor) devices, as an advanced wastewater treatment technology, have demonstrated high treatment efficiency in practical applications. However, they also have some drawbacks that limit their wider application. The following are some of the drawbacks of integrated MBR devices:

[0003] 1. High operating costs: Frequent membrane replacement, expensive membranes, and high energy consumption are the main reasons for high operating costs. High energy consumption mainly comes from the large aeration volume of the system and other power consumption during the treatment process.

[0004] 2. Membrane fouling: The accumulation of recalcitrant organic matter can inhibit microorganisms and exacerbate membrane fouling. Membrane fouling leads to decreased membrane flux, deterioration of effluent quality, and may even require frequent replacement of membrane modules.

[0005] 3. Sludge treatment issues: Long-term operation without sludge discharge will lead to a continuous increase in sludge content, causing the MBR membrane to become easily clogged and resulting in a sharp drop in effluent flow. High concentrations of sludge will also increase the total phosphorus (TP) content in the wastewater, affecting the quality of the effluent.

[0006] There is a need for a device that can reduce operating costs, clean membrane modules, and solve sludge treatment problems. Utility Model Content
