Abstract

The invention discloses a method for preparing split bricks by utilizing sludge in a red lotus lake. The method comprises the following steps of: drying a raw material, namely the sludge in the red lotus lake, to form particles, adding 16% of quartz sand, 25% of cement, 16% of emulsion, 12% of flame retardant, 13% of fly ash, 16% of modified industrial waste slag, 3% of titanium dioxide, 5% of biological particles and water, mixing, then uniformly stirring, performing extrusion molding, then drying, and further calcining for preparation. According to the method disclosed by the invention, the sludge in the red lotus lake is utilized, and other raw materials are further added for producing the split bricks, so that the water quality in the red lotus lake can be improved, the harmless and resource comprehensive utilization of the sludge in the red lotus lake can also be realized, the waste can be turned into valuable things, and the produced split bricks can not only meet the using requirements of decorative materials for exterior walls of buildings, parks, gardens, squares and residential courtyards, but also be used as carriers for building novel materials.

Description

A kind ofly utilize red Lianhu mud to prepare the method for Splitting Tile
Technical field
The invention belongs to environment protection and utilization of resources field, be specifically related to a kind ofly utilize red Lianhu mud to prepare the method for Splitting Tile.
Background technology
Red Lianhu mountain shape once is free and easy colourful, and the loke shore complications cause, and Hu Cha, the peninsula are wherein dimly visible, and green hill is dark green, and lake water is so clear that you can see the bottom.Red Lianhu landscape is unique, and is with fresh air, without any pollution and noise.All of a sudden as heaven on earth, the Land of Peach Blossoms.Spring has the peach of dying young to be full of ridge, and there are red lotus 10000 points in the summer, and the winter faced wintersweet and met snow, and 8,000 mu of pure lake water of that water quality are more arranged to a rich perfume of osmanthus blossoms was wafted to us by the breeze the autumn, and transmit the landscape of the funny wild goose of fisherman's song every morning and evening for you, just as a rare bright jewel.
because exploitation is excessive, and the Changjiang river current slow down, contain a large amount of microorganisms in current red Lianhu mud, pathogenic agent, heavy metal and organic pollutant, be not good at causing the secondary severe contamination as processing, particularly enter season in midsummer, rising along with temperature, having a large amount of blue-green algaes in red Lianhu water produces, but analyze and find from the production process of blue-green algae, it not only has relation with water quality temperature, and with red Lianhu in a large amount of mud of existing close relationship is arranged, present water conservancy at different levels environmental administration every year clears out later disposal to the mud of red Lianhu, Main Means or landfill and burning disposal are main, owing to containing a large amount of organism and heavy metal in mud, as adopt landfill, can bring great harm to soil, simultaneously because the mud water ratio is higher, mechanical property is poor, not only take the landfill place, often can also cause secondary pollution.As adopt burning disposal, and investment and running cost are all higher, and particularly energy consumption is larger, also exists simultaneously the problem of the off gas treatment while burning.Therefore, properly settling the problem of utilizing of red Lianhu mud, become the task of top priority, is also effectively to solve red Lianhu water quality, prevents the important topic that blue-green algae grows.
Summary of the invention
There is technical deficiency in the technical problem to be solved in the present invention at present mainly for the disposal of red Lianhu mud, provides that a kind of cost is low, effective, applied widely, a kind of of non-secondary pollution utilizes red Lianhu mud to prepare the Splitting Tile method.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind ofly utilize red Lianhu mud to prepare the method for Splitting Tile, with the dry material of the red Lianhu mud of raw material, add quartz sand 16%, cement 25%, emulsion 16%, fire retardant 12%, flyash 13%, modified industry waste residue 16%, titanium dioxide 3%, biological particles 5% and water and mix rear uniform stirring, by carrying out drying after extrusion molding, then make after calcining.
The dry material of described red Lianhu mud is formed by red Lianhu mud drying and crushing, and its water ratio is 20%~40%.
The pressure of described extrusion molding is 30~50Mpa, and the forming pressure hold-time is no less than 2 seconds.
Described drying temperature is 80 ℃~90 ℃, and be 5~10 hours time of drying.
Need place under field conditions (factors) 24 hours~48 hours.
Described calcining temperature is 1000~1100 ℃, and calcination time is 12~18 hours
The present invention utilizes red Lianhu mud and adds other raw material production Splitting Tiles, can realize the lifting of red Lianhu water quality, also can realize the innoxious and comprehensive utilization of resources of red Lianhu mud, it is turned waste into wealth, the Splitting Tile of producing can meet building outer wall decorative material, park, the service requirements of gardens, square, house garden, again can be as the carrier of building type material.
The present invention can solve the difficult problem that red Lianhu sludge treatment is disposed from source, thoroughly solved the problem of red Lianhu heavy metal in sludge, pathogenic agent and organic pollutant, has realized the renewable resource utilization of mud, has avoided the generation of secondary pollution.it is good that the Splitting Tile of producing not only has folding strength, the characteristics such as scour resistance is good, and the Splitting Tile of producing is after high-temperature calcination, can not produce secondary pollution, can save the required soil that takies of a large amount of landfills, also can effectively avoid the exhaust emission environmental problem that adopts burning to bring, carrying out promoting the use of of environmental renovation and building outer wall decorative material in conjunction with present China simultaneously, from resource circulation utilization, meet China environmental protection comprehensive utilization of resources requirement, the relatively more applicable building outer wall decorative material of this Splitting Tile and park, gardens, square, house garden and afforestation ecological engineering.
