The method of row Treatment of Sludge.
Background technique
In recent years, with the continuous propulsion of urbanization process, the urban wastewater treatment firm in China enters a high speed and increases
The long stage.The sludge yield of national sewage treatment plant in 2015 has broken through 30,000,000 tons (with 80% moisture content according to incompletely statistics
Meter).But long-standing " the light mud of heavy water " phenomenon leads to specific resistance to filtration during the construction of wastewater treatment in China factory and operation
Facility wretched insufficiency, resource utilization be not horizontal universal high.Since mud organic substance content is high, it is smelly easily to degenerate, and contain cause of disease
The poisonous and harmful substances such as body, heavy metal and persistence organic pollutant, if without dealing carefully with disposition, easily to water body, soil
Etc. causing secondary pollution, threatening environment safety and publilc health.
The biological treatment of sludge realize in sludge to greatest extent the conversion of substance and the energy with separate, be that one kind can be held
Continuous sewage sludge harmlessness, recycling treatment disposal options.But the biological treatment of sludge is generally limited by more difficult broken in solid particle
The cell wall rigid structure of solution and slow larger molecular organics hydrolytic process.In response to this problem, scholars expand a series of
Sludge pretreatment research, including ultrasonic wave cracks, the conditioning of ozone treatment, microwave, hot alkali treatment, cellulase treatment etc..Wherein,
Biological enzyme pretreatment belongs to the strengthening process of biological treatment because of it, have the advantages that easy to operate, mild condition, activation energy it is low etc. and
It has received widespread attention.The enzyme characteristic of biological enzyme makes it have salient feature, while also it being caused to deposit in practical applications
In certain restrictive condition: (1) vulnerable to external condition influence deactivation, most of enzyme is protein, be easy by high temperature,
Strong acid, highly basic and heavy metal influence and lose activity, and poisonous and harmful substance that may be present is same in sludge complicated ingredient
It will lead to biological enzyme to lose activity and be difficult to the effect that plays a role；(2) application cost is higher, and the production cost of native enzyme is higher,
So its application cost in sludge also correspondinglys increase.
Therefore, it develops a kind of high treating effect and practical sludge treating agent and processing method is with very important
Meaning.
