Description
Technical field
The present invention relates to sludge treatment fields, more particularly to a kind of municipal sewer mud purification method.
Background technique
In urban sanitation work, need periodically to remove rubbish, the sludge etc. in sewer, to guarantee that sewer is unobstructed.
With the high speed development of China's urban construction, the length of city sewer is also increased rapidly, and the dredging work of sewer becomes to get over
Come heavier.The complicated component of sewage sludge also contains a large amount of organic matter, difficult to degrade except containing in addition to a large amount of moisture
The ingredients such as organic matter, various trace elements, pathogenic microorganism and parasitic ovum, heavy metal and salt, if not dealing carefully with these
Mud, it will cause these mud to flow into river, causes ecological pollution.
Summary of the invention
The purpose of the present invention is to provide a kind of municipal sewer mud purification methods of avoidable ecological pollution.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of municipal sewer mud purification method, comprising the following steps:
(1) mud is collected: being collected the mud in sewer by sludge vehicle, and is transferred to sludge-tank；
(2) it pre-processes: the flocculant of 3~5kg being added in every cube of mud, the mud added with flocculant is stirred equal
2~3h is stood after even, is extracted out the waste water of muck surface by water pump after standing；
(3) sterilizing: after waste water exhausts, being added the fungicide of 2~3kg in every cube of mud, quiet after mixing evenly
4~6h is set, the molysite of 1~2kg is then added in every cube of mud；
(4) getting fat: the catalyst of 3~4kg is added in every cube of mud, sprinkles sodium hydroxide, hydrogen-oxygen after uniform stirring
Change sodium with a thickness of 3~4cm, and cover film and seal sludge-tank and ferment, fermentation time is 2~3d；
(5) it dries: the mud after fermentation being salvaged, is dried by rotary kiln, and the mud after drying is led to
It crosses pulverizer and breaks into powdery；
(6) 0.2~0.4kg of cinder, 0.1~0.2kg of plant ash, fine sand system fertilizer: are added in the mud of the powdery of every kg
Base manure is made in 0.3~0.4kg and 0.3~0.4kg of clay after mixing evenly.
Include the parts by weight of following components in every kg fungicide in the step (3): 4~6kg of hypochlorous acid, quick lime 3~
2~4kg of 5kg and calper calcium peroxide.
Catalyst in the step (4) is yeast.
The present invention has the effect that
(1) by setting pre-treatment step, the waste water in mud can be separated, to improve the efficiency of mud purification；
(2) by setting sterilizing step, the pathogenic microorganism and parasitic ovum in mud be can remove, while by adding
Enter molysite, the stench of mud can be reduced, causes ecological pollution when to avoid using mud；
(3) by setting getting fat step, the fertility in mud can be improved, to improve the utilization efficiency of mud；
(4) by the way that sodium hydroxide is added, temperature when mud fermentation can be improved, to shorten fermentation time, improve fermentation effect
Rate；
(5) by setting baking step, it can remove remaining moisture in mud and be convenient for simultaneously with reducing the volume of mud
Later period system fertilizer；
(6) fertile step is made by setting, the fertility in mud can be mixed with cinder, plant ash, fine sand and clay, is avoided
Fertility is lost；
(7) by the way that cinder is added in the mud of powdery, insert the mud of powdery in cinder, in order to fertility storage,
Fertility is lost after can avoid rain drop erosion.
