Abstract
The utility model is a membranous biological reactor that belongs to the field of water treatment equipments. The technical proposal of the reactor is as follows: a filter bed is included; a water inlet is provided at the bottom of the filter bed; a biological activated carbon filter bed is provided close to the bottom of the filter bed and above the water inlet; and membranous components are provided at the top of the biological activated carbon filter bed. The proposal permits the passage of slightly polluted water through the biologically active carbon filter before reaching the membranous components, and thus the utility model has a simple structure, low manufacture costs, and optimal purifying effects.
Description
Technical field
The utility model relates to a kind of membrane bioreactor, relates in particular to a kind of integral type film biological reactor.
Background technology
Membrane Bio-reactor Technology is an emerging water treatment new technology, is the combination of traditional biological treatment process and membrane separation technique, successfully is applied to water treatment.Membrane bioreactor generally is made up of membrane separation assemblies and bio-reactor two portions, and the position according to membrane module is provided with mainly is divided into two kinds of separated type and submergeds.The membrane bioreactor combination process of submerged is that membrane module is inserted in the bio-reactor, obtain filtrate through film, material such as suspended substance and active sludge is trapped within the bio-reactor, for high ammonia nitrogen, high organic micro-polluted source water or the filtration flux of film is reduced, resistance increases, increased energy consumption, operational management inconvenience.
Summary of the invention
The utility model is at the existing in prior technology shortcoming, and provide a kind of technical scheme of integral type film biological reactor, this scheme adopts at micro-polluted water through being provided with the primary purification device of biologic active carbon filtration layer before the membrane module, it is simple in structure, low cost of manufacture, good purification.
The utility model is realized by following technical measures: it comprises the filter tank, bottom in the filter tank is provided with water-in, in the filter tank,, be provided with membrane module on the top of biological activated carbon filtering layer near bottom and above water-in, be provided with the biological activated carbon filtering layer.
In the bottom of described membrane module, the top of biological activated carbon filtering layer is provided with aerating apparatus.Establish aeration tube in membrane module bottom, so that membrane module is cleaned, its aeration intensity only need satisfy the requirement of cleaning.This is that therefore, aeration intensity is lower because do not need biological activated carbon fluidisation in water.
Be provided with aerating apparatus and back-purge system in biological activated carbon filtering layer bottom.Can when influent ammonia nitrogen is higher, carry out aeration aerating like this and, keep its cleaning unobstructed regularly to the biological activated carbon filter back flushing.Specifically comprise the filter tank aeration tube and the filter tank recoil tracheae that are connected with biological activated carbon filtering layer bottom cavity.Be provided with the water purification water outlet on the top in filter tank.The water-in that bottom, described filter tank is provided with is connected with the filter tank backflushing water intake pipe with the filter tank water inlet pipe.
This utility model can design assembling in the following way, space more than the biological activated carbon filter charcoal layer is increased, membrane module is placed in the water on filtering layer top, when filter tank water level and the clean water basin water level discrepancy in elevation bigger, can utilize the waterhead water outlet, reduce working cost, biological activated carbon filter adopts upwards stream mode, the water inlet of bottom, pond, and at bottom, pond aeration, aeration rate is according to influent ammonium concentration, and gas: water generally is no more than 0.5: 1, as ozonation technology and when adopting pure oxygen to be ozone gas source, aeration not.Usually because aeration rate is little, the biological activated carbon filtering layer still is maintained fixed the state of bed, and the water of handling through the biological activated carbon filtering layer filters water outlet on top by membrane module, establishes aeration tube in membrane module bottom, so that membrane module is cleaned, aeration intensity only need satisfy the requirement of cleaning.Owing to do not need biological activated carbon fluidisation in water, therefore, aeration intensity is lower.In the biological activated carbon filter bottom back-purge system is set, regularly to the biological activated carbon filter back flushing.Though biological activated carbon filter is carried out aeration, owing to the filtration crown_interception of membrane module, there is not the losing issue of biological activated carbon, because to biological activated carbon filtering layer aeration, solved under the high ammonia nitrogen situation the insufficient problem of dissolved oxygen in the biological activated carbon filter, guaranteed removal ammonia nitrogen.
