Abstract

The invention discloses an integrated membrane bioreactor for recycling schoolyard wastewater. The integrated membrane bioreactor comprises a water inlet tank, a water inlet pump, an inclined plate, a membrane bioreactor, a membrane component, a sucking pump, a sludge discharge hole and an aerator, wherein the water inlet tank is connected with the water inlet of the membrane bioreactor via the water inlet pump; the sludge discharge hole is formed in the bottom of the membrane bioreactor; the inclined plate, the membrane component and the aerator are arranged inside the membrane bioreactor; the aerator is arranged at the bottom of the membrane bioreactor; the inclined plate is positioned on the water inlet side of the membrane bioreactor; the membrane component is positioned on the water outlet side of the membrane bioreactor and is connected with the sucking pump. As the integrated membrane bioreactor is organically combined with schoolyard wastewater, not only is schoolyard wastewater effectively treated, but also treated water can be recycled for toile flushing, greening and the like, and environmental benefits and economic benefits of urban pollution treatment, energy conservation and emission reduction and pollutant recycling and reuse are increased to a very large extent.

Description

technical field [0001] The invention relates to a membrane bioreactor, in particular to an integrated membrane bioreactor for reuse of campus wastewater. Background technique [0002] With the vigorous development of education in our country, the scale and number of schools are also increasing day by day. As a large water user, the school has a low pollution level of domestic wastewater and is easy to treat. It is mainly composed of laundry wastewater, canteen wastewater, toilet flushing and shower wastewater, accounting for about 70-80% of campus water consumption, and the COD of sewage water is 2000mg / L Around 800mg / L for ammonia nitrogen, and around 50g / L for SS. There are more than 2,000 colleges and universities across the country, and the per capita water consumption of students is 170 tons. Most of the sewage is discharged to nearby sewage treatment plants for treatment, which increases the pressure on municipal pipelines and sewage treatment plants. In particular, ...
