Abstract
The invention provides a kind of method of efficient process riverway sludge, the mud accumulated for a long time using river course, the materials such as stalk, wood sawdust, rice bran are mixed, are fermented, then add the extra-nutrition element such as phosphate fertilizer, night soil, it is in ecological organic fertilier to prepare, the problem of sludge treatment is difficult is not only solved, and rationally make use of the materials such as stalk, wood sawdust, rice bran, the influence that crop straw burning etc. is caused to amblent air temperature is alleviated, green non-pollution, market value is big.
Description
Technical field
The present invention relates to sludge treatment field, and in particular to a kind of method of efficient process riverway sludge.
Background technology
Mud and muck soil are deposited in hydrostatic or slowly flowing water environment, and with the one of microbial action
In kind structured soils, mud in banking process, vegetation etc. can be constantly mixed into, constantly fermentation, mud has high micro- life in itself
Matter-element element and nutrition；Sludge treatment on the market be generally solidification, dehydration, stably, desiccation or burning, fail to make full use of, it is real
On border in the plant cultivation of large area, many using ecological organoclay, price is high, and mud such as is converted into organic great soil group, then had
There is great market.
The content of the invention
In view of this, it is an object of the invention to provide a kind of method of efficient process riverway sludge, it is possible to resolve riverway sludge
Processing is difficult, cost is high, without income the problem of.
In order to solve the above technical problems, the technical scheme is that：
A kind of method of efficient process riverway sludge, comprises the following steps：
A. crush：It is placed in through mud in homogenizer, stirring is crushed；
B. removal of impurities：Multiple screening process is carried out to mud using the different screen cloth in aperture, the different mud of particle diameter is obtained；
C. it is aerated and dehydrates：The mud particle diameter obtained in step b is added in different aeration tanks, at aeration
Reason, aeration pressure is 1.2-1.8MPa, then, and the mud of Air Exposure is carried out into press filtration, dewater treatment, drying is subsequently placed in
In case, heat drying, further dehydration, obtains soft mud pellet；
D. by the mud pellet obtained in step c mixed straw powder, wood sawdust, rice bran in proportion, it is placed in stirring in mixer
Mix, after stirring, be sprinkled into the mixed liquor of water, urea and leavening, be placed in casing, external heat, ferment at least 48h；
E. after the completion of fermenting, spread out, sprinkle the mixed liquor of phosphate fertilizer and night soil, then the mud pellet in step c is uniformly sprinkled
Thin layer, dries 1-2h；
F. packed by quality, i.e. ecological organic fertilier.
Preferably, in the step c temperature of heat drying at 80-110 DEG C.
Preferably, the mass ratio of the stalk powder, wood sawdust, rice bran and mud pellet is：3:1:1:12.
Preferably, the mass ratio of the water, urea and mud pellet is：0.05:0.01：10, appropriate leavening.
Preferably, the mud pellet layer height fermented in the casing is in below 2m.
Preferably, the phosphate fertilizer, night soil and mud pellet are in mass ratio：1:1：50.
Beneficial effects of the present invention：The mud accumulated for a long time using river course, mixes the materials such as stalk, wood sawdust, rice bran, hair
Ferment, then the extra-nutrition element such as phosphate fertilizer, night soil is added, it is in ecological organic fertilier to prepare, and not only solves asking for sludge treatment hardly possible
Topic, and the materials such as stalk, wood sawdust, rice bran are rationally make use of, the influence that crop straw burning etc. is caused to amblent air temperature is alleviated, it is green
Color is pollution-free, and market value is big.
Embodiment
Hereinafter, the embodiment to the present invention is described in further detail, so that technical solution of the present invention is more readily understood
And grasp.
