Description
Technical field
The utility model is mainly concerned with technical field of sludge treatment, refers in particular to the high concentration evil that a kind of sludge pyrohydrolysis is produced
The device of odour processing.
Background technology
According to《National environmental protection " 12 " is planned》And《" 12 " whole nation urban wastewater treatment and regeneration are set
Apply construction plan》Requirement, by 2015, sewage treatment facility rate of load condensate brought up to more than 80%, and treatment rate of domestic sewage reaches
To 85%；At that time, the sewage disposal scale of China is up to 208,050,000 m3/d.According to house town and country construction portion on national city
The town sewage treatment facility first quarter in 2016 builds the circular with running situation：By in by the end of March, 2016, the whole nation sets city city
City, county add up to build up urban wastewater treatment firm 3910, and sewage treatment capacity is 1.67 hundred million m3/d；The sludge supervened (contains
Water rate is in terms of 80%) nearly 50,000,000 t/a or so (every ten thousand m35~10t of sewage production mud).Moreover, the numeral also with 10%~
15% speed increase.
The sewage disposal cause of China in the past few decades, has there is breakthrough progress.Yet with China
There is serious " the light mud of heavy water " phenomenon in construction of wastewater treatment plant, cause a large amount of sludge " overstocked ", the place of reasonable benefit/risk is not obtained
Reason disposal.Accordingly, with respect to more ripe sewage disposal technology, specific resistance to filtration technology is in China still in starting
Stage, and slower development.According to《" 12 " whole nation urban wastewater treatment and the planning of regeneration Facilities Construction》：To 2015
Year, the sewage sludge harmlessness processing disposal rate of municipality directly under the Central Government, provincial capital and cities specifically designated in the state plan reaches 80%, and other the planned cities reach
70%, county town and emphasis town reach 30%.But by the end of the year in 2014, national specific resistance to filtration Facilities Construction was only completed " ten
Two or five " the 43.4% of the object of planning, i.e., 224.81 ten thousand ton/year, breach is huge.
Anaerobic digestion is widely used as one of Treatment of Sludge important technology in American-European countries, is also encouraged energetically by China
Development.But so far, China's only more than 50 family's sewage plants have anaerobic sludge digestion equipment, and 40% or so stops transport.Whole nation warp
The sludge of Anaerobic Treatment is crossed less than 2%.It is main reason is that China's sludge generally existing sand content height, the content of organic matter are low
Problem, causes that anaerobic digestion operational efficiency is poor, and gas production is low.Pyrohydrolysis can have as a kind of emerging sludge pre-treatment techniques
The water and organic matter of microorganism and extracellular polymeric in microorganism structure in effect destruction sludge, release sludge, and will be difficult to give birth to
The larger molecular organicses of thing degraded are hydrolyzed to the small organic molecule of easily biological-degradable, so as to improve digestion and the dehydration property of sludge
Energy.
Existing traditional pyrohydrolysis processing mode is " catalytic oxidation desulfurization+chemistry alkali cleaning+biological deodorizing ", and its equipment includes
Catalytic oxidation desulfurization tower, chemical caustic wash tower, biological deodorizing case, blower fan, humidification pump and humidification case.But traditional handicraft and equipment are present
Following defect：
1st, in foul smell hydrogen sulfide, sulfurous organic compound is easily caused catalyst inactivation in existing method, causes under treatment effeciency
Drop, the catalyst change frequency, which is improved, also results in operating cost raising.
2nd, the set odor removal is not provided with foul smell cooling system, and high temperature foul smell is easily caused microorganism in biological deodorizing system and lost
It is living.
3rd, the organic odor gas concentration such as methyl mercaptan, methyl sulfide and trimethylamine height and foul smell olfact pole in pyrohydrolysis foul smell
Low, this method is relatively low to organic matter foul gas removal efficiency, it is impossible to ensure that pyrohydrolysis, especially high-temperature-hot-water are taken off at foul smell
Manage qualified discharge.
