Description
Technical field
The present invention relates to technical field of sewage, especially a kind of magnetic sludge zero-emission sullage continuous processing technique and
Dedicated unit.
Background technique
With the increase of city domestic sewage and Industrial Wastewater Treatment amount, the yield of excess sludge is also being increased rapidly,
Only municipal China generates municipal sludge of 30,000,000 ton of -4,000 ten thousand tons of moisture content 80% or so every year.The year two thousand twenty is expected, I
The municipal sludge yield of state is up to 60,000,000 ton -9,000 ten thousand tons.The volume of sludge is far smaller than sewage volume, but for dirt
The disposition cost of mud can account for or even surmount 50% or more of entire sewage treatment plant's general consumption, to sewage treatment discharge
The processing disposition of excess sludge is the problem of perplexing people for many years, and especially the factors such as economy, environment and regulation are increasingly tight in recent years
The limitation of lattice so that sludge routine method of disposal using more and more difficult, so in this context, various mud decrement skills
Art is come into being.The minimizing of excess sludge can be divided into the subsequent minimizing and process minimizing of sludge.Sludge process minimizing
Refer in the treatment process of sewage, by the operational process of change technique, or use certain technological means, is guaranteeing not
Under the premise of influencing sewage effluent quality, the yield of excess sludge is made to reach minimum, fundamentally reduces the yield of sludge, it is all
As aerobic-precipitating-anaerobism (OSA), high-solubility oxygen aeration system, aerobic-anaerobism alternate treatment technique and two-part are dirty
Mud decrement process etc. can realize mud decrement from biochemical treatment process.It is final remaining but due to being biochemical method after all
Sludge still can occur, it is still desirable to realize recycling, innoxious processing by subsequent processing.And the minimizing of subsequent sludge
Can be by means such as physics, chemistry, biology or process integrations, but must take into account the economic benefit and Environmental Effect of process
Benefit.The excess sludge of excess sludge especially secondary settling tank, volume is big, and moisture content is very high, deals with and is difficult and excess sludge
One bottleneck problem of minimizing.
By taking sanitary sewage disposal relatively common at present as an example, activated sludge process is often used, eventually passing through secondary settling tank will
Activated sludge is separated, and a portion is back to and provides a large amount of microorganisms into being mixed at water with sewage, another part send to
Sludge-tank carries out subsequent processing.Although which is widely used, but its energy consumption is high in dehydration process, and produce
The processing disposal process of raw solid sludges is highly difficult, so sludge zero discharge technology becomes the target that current people pursue.

Portion's connection；Mud discharging mouth is arranged in deozonization slot left lower, and water out is arranged in deozonization slot left upper portion, which passes through first
The pretreating sewage import of water pump connection activated sludge aeration tank.
3. a kind of dedicated unit of magnetic sludge zero-emission sullage continuous processing technique according to claim 2, feature
Be: first cleaning shoe and the second cleaning shoe is that the inclined plate being obliquely installed by two is formed by connecting.
4. a kind of dedicated unit of magnetic sludge zero-emission sullage continuous processing technique according to claim 2, feature
It is: lower vertical plate is set below the bending part of first cleaning shoe.
5. a kind of dedicated unit of magnetic sludge zero-emission sullage continuous processing technique according to claim 2, feature
Be: the mud discharging mouth is located at the lower section of the second cleaning shoe, and is located at the left side of riser.
