Description

A kind of integrated MABR device for black and odorous water improvement
Technical field
This utility model is related to a kind of device for black and odorous water improvement and administering method and in particular to one kind is for black The integrated MABR device of smelly water body treating and administering method.
Background technology
River course, as the important component part of urban ecological system, has offer aquatile environment, beautifying city, landscape Amusement etc. multiple ecological functions, additionally undertake control flood and drain flooded fields, the critical function such as environment of regulating the climate, pollutant of dissolving, be city The basis that city depends on for existence and development.With the fast development of China's urban economy, urbanization, process of industrialization constantly advance, City river water environment is heavily contaminated and destroys, and oxygen-consuming organic pollution, nitrogen and phosphorus content remain high and lead to urban river water Body is black smelly and eutrophication situation is extremely serious.
In view of the particularity of city river, it is significantly poor that black-odor riverway water restoration and treatment and traditional sewage disposal exist The opposite sex.Divide according to action principle, current domestic and international application is broadly divided into Physical, change in black-odor riverway aquatic ecological restoration technology Method and bio-ecological process three major types:
Physical is broadly divided into diversion erosion and deposition, cuts dirty pollution treatment, Sediment Dredging etc..Such method investment and operating cost are relatively Height, enforcement difficulty is larger to slacken water body self-purification ability thereby increases and it is possible to destroy the original biome in river course, thus being restoration of the ecosystem It is negatively affected.
Chemical method is primarily referred to as removing pollutant in eliminating water using chemical agent.Such method implements simple, instant effect, But easily cause secondary pollution of water.
Bio-ecological process refers to defeated using animal, plant, the purification of microorganism and multiple biological food chain being formed Go out purification and the reparation that forwarding function completes polluted-water.Such method stably effectively, secure persistent, energy resource consumption few, but its Clean-up effect is affected by multiple condition such as water quality, the hydrology and weather and factor, and responding time is longer, need to periodically manage, and not It is applied to serious pollution river regulation.
MBR membrane bioreactor, as rising in recent years sewage disposal technology, achieves for black-odor riverway water remediation Good effect, compared with conventional river course recovery technique, its treatment effect significantly improves, and operational management is more convenient, takes up an area face Long-pending less, but there is fouling membrane, clogging seriously, need periodically to carry out dosing backwash, and because malodorous black water is contained within relatively Many surfactants, can produce substantial amounts of foam during oxygenic aeration, and with volatile contaminant loss, endanger Surrounding enviroment, air stripping loss larger, oxygen utilization rate is low, fan energy consumption virtual height, in addition single MBR membrane bioreactor lack de- Nitrogen efficiency, need to set up additional process to meet black smelly river total nitrogen and remove requirement.
