Abstract
The invention relates to a process for preparing baking-free bricks by using bio-degraded sludge. The process comprises the following steps: (1) performing fermentation inactivation treatment to the bio-degraded sludge; (2) drying the inactivated sludge in air; (3) performing crushing pre-treatment to the sludge; (4) uniformly mixing the crushed sludge with lime, calcium sulfate dihydrate, slag, cement and Gubang CN-1 soil stabilizer materials; (5) feeding the mixed materials into a brick press, and forming green bricks while controlling the pressure to be 1200KN; (6) transporting the green bricks to a storage area, and naturally drying in the shade for 7 days while preventing the green bricks from sunshine irradiation and rain, thus obtaining product bricks. Due to the adoption of the process, secondary pollution of various degrees to the environment caused by the bio-degraded sludge generated in a penicillin production wastewater treatment process is avoided, the zero adding of the clay is realized, and furthermore, the using amount of non-renewable resources is reduced and the air pollution caused by flue gas emission are avoided.
Description
Technical field
The present invention is the technique relating to a kind of making brick from sludge, particularly relates to a kind of technique using biological degradation mud making burn-free bricks.
Background technology
In modern society, along with industrial expansion environment protection more and more causes the attention of people, especially the process of industrial waste is become to the effective means of environment protection, obtained investigation and application widely.Penicillin is antibacterials the most frequently used clinically, has made tremendous contribution to the health of the mankind.Can produce a certain amount of biological degradation mud in waste water produced from penicillin production treating processes, at present its process be there is no to effective treatment measures of economic environmental protection, no matter which kind of current processing mode all can cause the secondary pollution of environment in various degree.In addition, the demand of China's building trade to brick is huge, conventional sintering brick be utilize take farmland clay through sintering make, thus cause soil resource to run off in a large number, ruin field phenomenon very serious, current China has prohibited and has produced and use clay to fire brick for industry and covil construction.
Therefore, the pollution caused physical environment in order to avoid biological degradation sludge treatment is improper, also in order to avoid taking the destruction of farmland clay-brickmaking to soil resource, need to develop a kind of biological degradation mud using pharmacy wastewater treatment process to produce and prepare non-burning brick technique, to solve the biological degradation mud that can produce in waste water produced from penicillin production treating processes to the pollution problem of environment, solve simultaneously and do not add clay and finished product and all need to carry out to fire because existing brickmaking technology process departs from and caused to take when farmland clay destroys soil resource and fires energy consumption and fume emission to the environmental problem of topsoil.
Summary of the invention
Technical problem to be solved by this invention overcomes prior art the lack of standardization and situation of existing brickmaking technology to environmental disruption, the wasting of resources provides a kind of technique of biological degradation mud making burn-free bricks to biological degradation sludge treatment, and this technique can realize zero of clay and adds and can avoid biological degradation sludge pollution environment and brickmaking to a large amount of consumption of the energy, fume emission to the pollution of air.
Technical problem of the present invention is realized by following technical scheme.
A technique for biological degradation mud making burn-free bricks, this technique comprises the following steps: after (1) carries out fermentation inactivation treatment (2) deactivation to biological degradation mud, mud carries out airing process; (3) comminution pretreatment is carried out to mud; (4) by even for the mixing of materials such as the mud after pulverizing and lime, terra alba, slag, cement, solid nation CN-1 soil-solidified-agent; (5) mixture being sent into brick press control pressure is 1200KN, makes adobe; (6) be transported to stacking place, avoid direct sunlight and drench with rain, after naturally drying in the shade 7 days, becoming finished bricks.
The technique of above-mentioned a kind of biological degradation mud making burn-free bricks, step (1) carries out fermentation inactivation treatment 5 to 7 days to biological degradation mud.
The technique of above-mentioned a kind of biological degradation mud making burn-free bricks, after step (2) deactivation, mud carries out filter-press dehydration, airing process, and moisture controlled is about 15%.
The technique of above-mentioned a kind of biological degradation mud making burn-free bricks, step (3) carries out comminution pretreatment to mud, and particle diameter controls within 1mm.
The technique of above-mentioned a kind of biological degradation mud making burn-free bricks, the mud after pulverizing mixes with 4.5:1:0.5:3:0.99:0.01 ratio with lime, terra alba, slag, cement, solid nation CN-1 soil-solidified-agent by step (4).
The technique of above-mentioned a kind of biological degradation mud making burn-free bricks, the material mixed is sent into special brick press by step (5), and control pressure is 1200KN, makes adobe.
The technique of a kind of biological degradation mud making burn-free bricks of the present invention has following beneficial effect:
1, avoid the biological degradation mud that produces in waste water produced from penicillin production treating processes and secondary pollution is in various degree caused to environment, process for the biological degradation mud of pharmacy wastewater treatment process generation provides a kind of effective measure of economic environmental protection, has founded the new concept that pharmacy corporation environmental protection treatment is up to standard;
2, by can to realize zero interpolation of clay to the pre-treatment of biological degradation mud and the interpolation proportioning of other auxiliary material, thus avoid and ruin the generation that soil is adopted in field, avoid a large amount of losses of soil resource, for industry and covil construction brick provide new thinking;
3, baking-free brick-making is realized by the measure such as use the interpolation proportioning of biological degradation mud and a series of pre-treatment and other auxiliary material, dry in the shade, decrease the usage quantity of Nonrenewable resources and fume emission to the pollution of air, for new standard is set up in brickmaking industry.
