Abstract
The present invention relates to technical field of sludge treatment, particularly relate to a kind of sludge pre-treatment method.The present invention provides a kind of sludge pre-treatment method, comprises the following steps: step A: add water to, in mud, stir, obtain mud serosity；Step B: with mineral acid by the pH regulator of mud serosity to 26, stir；Step C: adding sludge dewatering pre-treatment medicaments in mud acid solution, interpolation limit, limit is quickly stirred；Step D: finally mud is processed 3 5min under the microwave that power is 320 800W.The present invention can remove mud stench, kills the harmful microorganism such as pathogen and parasite, improves sewage sludge harmlessness level, can greatly reduce the follow-up disposal of subsequent transportation expense, beneficially mud, simple to operate.
Description
Technical field
The present invention relates to technical field of sludge treatment, particularly relate to a kind of sludge pre-treatment method.
Background technology
Treatment of Sludge has multiple route, including landfill, burning, compost, making building materials, Land_use change etc., no matter takes
Which kind of processing method, sludge dewatering is all a pre-treatment link of non-the normally off key.But sludge structure is complicated and loose, Yi Cheng
Colloid, has the strongest hydrophilic, and cell interior water content ratio is great, gives the operation being realized physical property dehydration by active force
Bring challenges, often produce the problems such as dewatering efficiency is low, and energy consumption increases, equipment unreliability increase.
Summary of the invention
For defect or deficiency present in prior art, the technical problem to be solved is: provide a kind of dirty
Mud preprocess method, it is possible to first destroy colloidal stability and the cell micelle structure of mud before dehydration, improve follow-up dehydration
Efficiency.
To achieve these goals, the technical scheme that the present invention takes is to provide a kind of sludge pre-treatment method, including with
Lower step:
Step A: add water to, in mud, stir, obtain mud serosity；
Step B: with mineral acid by the pH regulator of mud serosity to 2-6, stir；
Step C: adding sludge dewatering pre-treatment medicaments in mud acid solution, interpolation limit, limit is quickly stirred；
Step D: finally mud is processed under the microwave that power is 320-800W 3-5min.
As a further improvement on the present invention, described mineral acid is sulphuric acid or hydrochloric acid or nitric acid.
As a further improvement on the present invention, the mixing time of described stirring is more than 10 minutes.
As a further improvement on the present invention, the mixing speed of described quick stirring is for being less than in 20r/ min, during stirring
Between be 30 minutes.
The invention has the beneficial effects as follows: the present invention can remove mud stench, kill harmful micro-life such as pathogen and parasite
Thing, improves sewage sludge harmlessness level, can greatly reduce subsequent transportation expense, and the follow-up disposal of favourable mud is simple to operate.
Detailed description of the invention
Below in conjunction with explanation and detailed description of the invention the present invention is further described.
The present invention provides a kind of sludge pre-treatment method, comprises the following steps:
Step A: add water to, in mud, stir, obtain mud serosity；
Step B: with mineral acid by the pH regulator of mud serosity to 2-6, stir；
Step C: adding sludge dewatering pre-treatment medicaments in mud acid solution, interpolation limit, limit is quickly stirred；
Step D: finally mud is processed under the microwave that power is 320-800W 3-5min.
Described mineral acid is sulphuric acid or hydrochloric acid or nitric acid.
The mixing time of described stirring is more than 10 minutes.
The mixing speed of described quick stirring is for less than in 20r/ min, and mixing time is 30 minutes.
Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert
Being embodied as of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of present inventive concept, it is also possible to make some simple deduction or replace, all should be considered as belonging to the present invention's
Protection domain.
