Abstract
The invention discloses a production method of sludge ecological environment-friendly vegetation blocks, which comprises the following materials in parts by weight: 50-60 parts of stone powder; 20-30 parts of cement and 18-23 parts of sludge, and the concrete production method comprises the following steps: the invention is characterized in that stone powder and cement are uniformly mixed according to the weight part ratio, then the sludge prepared according to the weight part ratio is diluted into sludge slurry by adding water, then the sludge slurry is pumped into the mixture of the stone powder and the cement and is uniformly mixed, finally, the uniformly mixed materials are sent into a pressing machine for pressing and forming, and the finished product is obtained by airing, and the invention has the advantages that: not only has no sewage and waste gas discharge and protects the environment, but also has simple and easy production method and well realizes the harmless treatment of the sludge.
Description
Technical Field
The invention relates to the technical field of components for ecological slope protection, in particular to the technical field of vegetation blocks for ecological slope protection.
Background
At present, the water bank protection of rivers and lakes in China is protected in a greening ecological mode, various organisms can survive and propagate on the protected water bank protection while the water bank protection is stable, and the integrity of an ecological system of the water bank protection is kept. At present, the vegetation blocks for slope protection which are applied more are all made of concrete.
However, in the early stage dredging process of rivers and lakes, a large amount of sludge and mud can be cleaned from the bottoms of the rivers and lakes, and if the sludge and mud are directly accumulated on the bank, the environment is not only influenced, but also unpleasant odor can be emitted. At present, another treatment method adopted by people is to use the sludge slurry as a raw material to manufacture the vegetation block for the concrete slope protection, in the using process, firstly, sludge slurry needs to be subjected to plate-and-frame filtering and extrusion to remove most of moisture in the slurry, then, a filter cake formed after extrusion is dried in the air or directly used for manufacturing the vegetation block for the concrete slope protection, and the treatment method has the defects that: firstly, the water squeezed out by filtration cannot be effectively and reasonably treated, if the water is directly discharged, environmental pollution is caused, and unpleasant odor can be emitted for a long time; secondly, if the filter cake formed after extrusion is directly used for producing the concrete vegetation block, the agglomerated sludge filter cake cannot be uniformly mixed with cement and stone powder, so that the product quality of the concrete vegetation block is influenced; if use after drying the filter cake, still need will dry the filter cake smash just, otherwise also can appear unable and cement and the even condition of mountain flour misce bene.
Disclosure of Invention
The invention provides a production method of sludge ecological environment-friendly plant growth blocks, which can carry out harmless treatment on sludge, does not need extrusion and airing, does not discharge sewage and waste gas and can ensure the product quality in order to solve the defects of the prior art.
The technical solution adopted by the present invention to solve the above technical problems is as follows:
the production method of the sludge ecological environment-friendly vegetation block comprises the following materials in parts by weight: 50-60 parts of stone powder; 20-30 parts of cement and 18-23 parts of sludge, and the concrete production method comprises the following steps: the method comprises the steps of uniformly mixing stone powder and cement according to the weight part ratio, diluting sludge with water according to the weight part ratio to form sludge slurry, pumping the sludge slurry into a mixture of the stone powder and the cement, uniformly mixing the sludge slurry and the cement, finally, feeding the uniformly mixed material into a pressing machine for pressing and forming, and airing to obtain the finished product.
Preferably, the water content of the sludge slurry after the sludge is diluted by adding water reaches 50-75%.
The invention adopts the technical proposal to achieve the following beneficial effects: the sludge is directly diluted into sludge slurry by adding water and then is uniformly mixed with the stone powder and the cement to manufacture the product, so that the conventional processes of filtering, extruding and drying are reduced, sewage and waste gas are not discharged, the environment is protected, the production method is simple and easy to implement, the harmless treatment of the sludge is well realized, and the problem that the product quality is influenced because the sludge cannot be uniformly mixed with the stone powder and the cement when being dried after being extruded or directly used as a raw material to manufacture the product is solved.
