Description
Technical field
The invention belongs to the technical fields using biotechnology processing sludge, and in particular to a kind of be reduced with metazoa remains
The reaction unit of remaining sludge.
Background technique
The processing of China's sanitary wastewater and industrial wastewater mostly uses greatly activated sludge process, and there is capital expenditure to save, handle for it
The good advantage of effect, but it always exists a maximum drawback, that is, it can generate in the process of running a large amount of remaining dirty
Mud.In traditional activated sludge process, every degradation 1kg BOD5(Biochemical Oxygen Demand, five biochemical aerobic
Amount) excess sludge that about 15-100L can be generated, for handling or the expense for the treatment of excess sludge accounts for about sewage treatment total cost
25%-65%, the expense that European countries are used to handle excess sludge every year is as high as 2,800,000,000 RMB.It is clear that any
The measure for advantageously reducing excess sludge will all bring huge economic benefit.
Secondly, various Treatment of Sludge and the fund that method of disposal needs are huge, at present in the world at 80% or more sewage
Manage factory's application is Wastewater Treated by Activated Sludge Process sewage, and such as in America and Europe, Treatment of Sludge capital cost accounts for sewage treatment plant's total capital investment cost
Ratio is up to 60-70%.In recent years, wastewater treatment in China factory sharply increases, and corresponding surplus sludge volume is also increasing, and
The excess sludge disposition means in China are mainly landfill, burning and compost or he uses, and these types of method, which all exists, to be difficult to overcome
Technical bottleneck, sludge treatment ability lags far behind the actual needs of sludge treatment, especially this year, with some new environments
The promulgation and implementation of method, the depth and range require sewage treatment are all significantly increased, and inevitably result in the yield of excess sludge
It is increasing, meanwhile, excess sludge disposition of keeping under strict control is tightened by country, all realizes strictly from sludge entrucking-transport and disposition each stage
Monitoring, supply falls short of demand in sludge transport disposition market, and the operating cost of sewage treatment plant increases substantially, the processing and disposition of sludge
The a great problem of environmental area will be become.The demand urgent in face of this needs to develop a kind of sludge reduction process, realizes dirty
Mud source reduction.Existing multiple technologies are used for sludge reduction at present, mainly use physical chemistry or biological means, mainly
It destroys cell combination water or melts born of the same parents' technology, it is subsequent to still need to add a large amount of medicament and filter press dehydration.
Its attention, the predation digestion on biological (sludge organism chain top) after directly utilizing, from food
Chain pyramid it can be seen that, energy from bottom to food chain top transmit during, 90% or more is all distributed with form of heat
Fall, to reduce sludge yield from source.In actual operation, pig kiss wheel animalcule and erythema wooden dipper body worm are reported and can largely bite
Sludge is eaten, notably under the action of them, sludge concentration is down to 3000mg/L from 10000mg/L in the time.But at present this
Kind method is merely resting on the laboratory research stage, and engineer application is less.Therefore, according to these metazoa metabolic characteristics, originally
Invention has devised a kind of reaction unit with metazoa decrement excess sludge, is suitable for urban wastewater treatment firm excess sludge
In engineer application.
