Filled membrane biological processor

Abstract

The invention discloses a filled membrane biological processor which comprises a water treatment vessel, a hollow fiber membrane group, an aeration pipe network, a water collecting main pipe and a bracket, wherein the hollow fiber membrane group consists of a hollow fiber membrane and a water collecting pipe; the water treatment vessel is internally provided with soliquoid with the density of 0.9 to 1.0g / cm, and the soliquoid consists of a multihole shell and filling materials; the material of the multihole shell is polypropylene or polyethylene; and the filling material is at least one out of activated carbon fiber, granular active carbon, mekralon, polyethylene fiber and ion exchange resin. The processor is beneficial for the degradation of organic substances, the elimination of the pollutant of ammonia nitrogen and the cleaning of the hollow fiber membrane; the breakage and enwinding of the hollow fiber membrane are avoided; besides, the processor is beneficial to the distribution of air, avoids the short circuit of air water, and reduces the air water ratio and energy consumption.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a membrane biological processor. Background technique [0002] At present, when using hollow fiber membranes to treat water, especially sewage and wastewater, there are some defects. First, due to uneven aeration, gas-water short circuit is easy to occur, and the flushing effect of the gas-water mixture on the surface of the hollow fiber membrane is insufficient. The pollutants on the surface of the hollow fiber membrane will be silted up, and the surface of the hollow fiber membrane will be blocked; secondly, the microorganisms lack a suitable "nest" in the hollow fiber membrane assembly - the biological carrier, which limits the growth and reproduction of microorganisms; The hollow fiber membranes are broken and entangled due to large swings under the action of air and water, resulting in a decline in the quality of the effluent; fourth, due to insufficient utilization ...
