Description
Technical field
The utility model belongs to the technical field using biotechnology processing sludge, and in particular to a kind of to be subtracted with metazoa
Measure the reaction unit of excess 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

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
Utility model has devised a kind of reaction unit with metazoa decrement excess sludge, and it is remaining to be suitable for urban wastewater treatment firm
In sludge engineer application.
