Increase.The safe handling of a large amount of sludge, handling problems annoying sewage treatment plant, and more and more sewage sludges are nowhere stacked,
Sewage treatment plant is caused to face the awkward situation for stopping operation.
Anaerobic digestion process is made of multistep microbial degradation process, including is acidified, is produced acid, methane phase stage.Hydrolysis is
The rate-limiting step of complex substrate anaerobic digestion containing particulate matter.Main cause is: most of organic matters are present in micro- in sludge
In biological cell, the hydrolysis of cell wall is more difficult, and anaerobic sludge digestion process is caused to take a long time.It is pre- by sludge
Processing can destroy the structure and cell wall of sludge, and sludge flocculation structure is made to change, and reduce sludge partial size, and intracellular organic matter is molten
Enter water phase out, fast hydrolyzing is small molecule compound the ectoenzyme under the action of, increases the yield and anaerobic digestion of methane
Efficiency.
The method of sludge pretreatment has much at present, and main method has Microwave Pretreatment, ultrasonic pretreatment, soda acid to locate in advance
Reason, Grape berry, biological treatment and combination pretreatment etc., the generally existing cumbersome, structure of the device that these methods use
Complicated, the disadvantages of short time consumption is long.
Utility model content
For the deficiency of current excess sludge anaerobic digestion preconditioning technique, present applicant proposes a kind of enhancing dewatered sludges
The device of anaerobic digestion performance, the device is easy to operate, time-consuming short.
To achieve the above object, the technical solution of the application are as follows: a kind of device for enhancing dewatered sludge anaerobic digestion performance,
Specifically include: sludge initial adjustment pond, sludge accurate adjustment pond and anaerobic digestion tower are equipped with submersible sewage pump a in sludge initial adjustment bottom of pond portion, described latent
Dirt pump a is connected with one end of blow-off line a, and the other end of the blow-off line a is put in sludge accurate adjustment pond, in sludge accurate adjustment pond
Bottom is equipped with submersible sewage pump b, and the submersible sewage pump b is connected with one end of blow-off line b, and the other end of the blow-off line b, which is put in, to be detested
Oxygen digests in tower；Liquidometer a is equipped in sludge initial adjustment pond, nitrite nitrogen monitors device a, blender a on-line；In sludge accurate adjustment pond
