Abstract
The invention discloses a kind of method for sludge treatment, first mix sawdust or stalk slag etc. by 10:50-100:1-2 weight ratio with sludge, Treatment of Sludge zymophyte powder；It is carried out heap fermentation 15-30 days using microbial fermentation bacterium in sludge；Then it carries out the technique such as burning again, reduces the discharge of poisonous and harmful substance in subsequent processing, the present invention adds sawdust in sludge, and the burning for being also beneficial to sludge is complete.By the method for the invention, become harmless soil constituent after Treatment of Sludge, can be used as fertilizer improvement soil fertility.
Description
Technical field
The invention belongs to a kind of environmental protection technology, the processing technique of specifically a kind of sludge.
Background technique
With the sharply expansion of city size, ever-increasing trend is presented in quantity of wastewater effluent, forms a large amount of sludge.These
Sludge passes through traditional extremely difficult processing of method.If these sludge stored for a long time, ambient atmosphere environment can be seriously affected.
Traditional method for sludge treatment includes sanitary landfill method, incineration method, the direct brick-making process of sludge, aerobic fermentation composting method
With direct solidification method etc..The substances such as middle microorganism, pathogen easily cause air environmental pollution in sludge handling process.
Summary of the invention
The object of the present invention is to provide a kind of processing method of sludge, harmful and noxious substance in the sludge that can effectively degrade,
In sludge handling process, the disposal of pollutants to environment is reduced.
Technical scheme is as follows:
A kind of method for sludge treatment, it is characterised in that the following steps are included:
(1), sawdust or stalk slag etc. are mixed with sludge, Treatment of Sludge zymophyte powder by 10:50-100:1-2 weight ratio；
(2), it is carried out heap fermentation 15-30 days using microbial fermentation bacterium in sludge；
(3), the mixing sludge after fermentation is sent into belt filter press filters pressing, obtains filter cake and filtrate；
(3), gained filtrate is sent into clarifier-tank, and flocculant is added by amount of filtrate and carries out secondary precipitation；
(4), the water outlet after precipitating flows into membrane module, carries out disinfection through the filtered water of membrane module, then sterilized device, kills water
Middle microorganism, is finally discharged or is utilized；
(5), filter cake is cut into the bulk no more than 20 centimetres, carries out desiccation；
(6), the filter cake after desiccation incinerator is sent into burn；
(7), clinker is transported as fertilizer or other purposes.
The sludge is municipal waste water treatment sludge.
Advantages of the present invention, Treatment of Sludge zymophyte powder have the multi-functional strain of anaerobism, oxygen-consuming.It is micro- in the product
Biology generates digestive ferment during growth and breeding, a large amount of organic wastes contained in the filter mud to decompose municipal wastewater treatment plant discharge
Object, and the foul odour in sludge is removed, the product of decomposition is converted further further through oxidation, reduction and hydrolysis, after
It is converted to organic fertilizer.Growth of the multi-functional strain in heap fermentation strengthens, effectively inhibition varied bacteria growing, to prevent
Generate the harmful substances such as stink and pathogenic bacteria.The condition provided for later period Treatment of Sludge.The present invention adds saw in sludge
The materials such as end can be effectively reduced the water content of sludge, while provide preferable habitat for multi-functional bacterium, be conducive to strain
Growth；Sludge after fermentation carries out filters pressing, and water content decline is sent incinerator to burn, reduced in sludge incineration after filter cake desiccation
The discharge of harmful substance pernicious gas, protects environment.The present invention adds sawdust in sludge, and the burning for being also beneficial to sludge is complete
Entirely.By the method for the invention, become harmless soil constituent after Treatment of Sludge, can be used as fertilizer improvement soil fertility.
Specific embodiment
A kind of method for sludge treatment, it is characterised in that the following steps are included:
(1), sawdust or stalk slag etc. are mixed with municipal waste water treatment sludge, Treatment of Sludge zymophyte powder by 10:80:1 weight ratio
It closes；
(2), it is carried out heap fermentation 30 days using microbial fermentation bacterium in sludge；
(3), the mixing sludge after fermentation is sent into belt filter press filters pressing, obtains filter cake and filtrate；
(3), gained filtrate is sent into clarifier-tank, and 1-3% high polymer coagulant is added by amount of filtrate and carries out secondary precipitation；
(4), the water outlet after precipitating flows into membrane module, carries out disinfection through the filtered water of membrane module, then sterilized device, kills water
Middle microorganism, is finally discharged or is utilized；
(5), filter cake is cut into the bulk no more than 20 centimetres, carries out desiccation；
(6), the filter cake after desiccation incinerator is sent into burn；
(7), clinker is transported as fertilizer or other purposes.
The present invention is in advance handled sludge with Multifunctional fermentation bacterium, pathogenic bacteria etc. in sludge of effectively degrading it is harmful at
Point, be conducive to subsequent treatment process.
Claims (2)
1. a kind of method for sludge treatment, it is characterised in that the following steps are included:
