Abstract
This invention relates to a kind of silt processing method. The method includes following steps: silt dehydration; cutting and granulation; then heat for drying. Dry temperature controlled at 100 to 300 deg, 200 deg is best. This invention solves the handling problem of municipal sewage plant, lake, watercourse and marshy silt. The silt after treatment could be directly used as vegetable manure.
Description
Technical field
The present invention relates to a kind of process for treating sludge.
Background technology
Present China's mud of having of lake, river course only, annual collection capacity can reach 7,000 ten thousand tons at least, adds the mud of municipal sewage system, and annual general collection amount can reach more than 100,000,000 tons.Gather mud, help river training, prevent water quality eutrophication and purifying city environment.
For the processing of mud and sludge, prior art mainly contains three kinds of treatment processs: the one, be poured directly in the sea.Do the Marine Pollution resource like this, prohibited by international community; The 2nd, take the method for burning.Big with this method power consumption, the cost height, but floor space is little when handling, and area, China Macao is handled mud and is all adopted this method at present; The 3rd, landfill.This can cause underground contaminated water source, and countries such as France have prohibited and made in this way.
Summary of the invention
The objective of the invention is for a kind of process for treating sludge that is used for municipal sewage plant, lake, river course and wetland is provided.
For realizing purpose of the present invention, this specification sheets provides a kind of process for treating sludge, may further comprise the steps: with sludge dewatering; The chopping granulation; Heating, drying then.The temperature of oven dry is between 100 ℃ to 300 ℃, and the best is 200 ℃.
The mud grain that this method oven dry back produces mixes with coal with 1% to 50% adding proportion scope, can make propellant combination.Mud grain after the oven dry and coal blended adding proportion the best are 10%.
The mud grain that this method oven dry back produces is sprinkled in the flowers and trees cultivation soil as fertilizer, also can put into the additive that phosphorus or potassium or nitrogen or multiple composition mix therein, makes its nutrition more comprehensively.
Typing is burnt in the pulverizing of mud grain, brickmaking, baking that this method oven dry back produces.
The invention solves the sludge treatment problem of municipal sewage plant, lake, river course and wetland, the mud finished product that obtains after the processing can be directly used in the fertilizer of flowers and trees plant, to the flowers and trees fertilising on urban afforestation band, motorway limit.This process for treating sludge is by the chopping granulation, cut brokenly the hydrobiont cell walls that contains in the mud, originally the moisture that is included in the cell walls fully is evaporated, has solved the problem that mud can't be dried fully, realized energy-conservation to mud, efficiently, dispose up hill and dale.
Purpose of the present invention, feature and advantage will be in conjunction with the embodiments, are further described.
Embodiment
Following embodiment is provided.To help to understand the present invention by embodiment, but not limit content of the present invention.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
Embodiment 1: this process for treating sludge, be used to handle the mud of river course, wetland, and it is transformed into fertilizer, fuel additive or is used for brickmaking etc.This method may further comprise the steps: with sludge dewatering; The chopping granulation; Heating, drying then.The temperature of oven dry is 200 ℃.
The mud grain that this method oven dry back produces mixes with coal with 10% adding proportion scope, can make propellant combination.
Embodiment 2: the mud grain that embodiment 1 described method oven dry back produces is sprinkled in the flowers and trees cultivation soil as fertilizer.
Embodiment 3: typing is burnt in the pulverizing of mud grain, brickmaking, baking that embodiment 1 described method oven dry back produces.Mud is manufactured fragment of brick to be used.
