The geotube technology is a brand new environmental protection technology that is vigorously innovated and developed by global village scientists and Hong Kong researchers after absorbing advanced low-carbon governance technologies and concepts in Europe and the United States, based on actual engineering applications. The technology integrates incoming water, separation, filtering and sludge dewatering and solidification treatment, and is equipped with a fully automated management system. Compared with traditional processes, the treatment performance is more stable, the process is simpler, the results are better, and the total input and treatment cost is more competitive.
Technical principles The equivalent pore size formed using the material of the earthen pipe bag has two dynamic factors, the filter structure and the liquid pressure in the bag, and the separation of mud and water by adding water purification agents, water leaches out of the pipe bag and sludge remains in the pipe bag. The leaching water completely meets the relevant emission standards and can be collected and recycled.
Filling: After the waste water or sludge is added to the drug, the soil pipe bag is filled by a pump.
Dehydration: Clean water reaches the pipe bag and more than 99% of the solid particles are stored in the earthwork pipe bag.
Solidification: The solid particles are stored in a tube bag.
Technical features / advantages
Economy / energy saving: no need for large equipment and plant investment; Only a small number of non-professional operators are required; The dewatering part of the sludge does not require electricity and has the advantage of energy saving and emission reduction.
Convenience: The diameter and length of the earthen pipe bags can be adjusted according to the needs, the plasticity is strong, and they can be stacked, and the transportation is convenient.
Environmental protection: The construction is completely closed, there is almost no noise, and it is not easy to cause secondary pollution.
High efficiency: Completely meets the treatment amount of wastewater and sludge, and the treatment capacity can be increased and decreased according to the pump flow.
The reduction effect is good: the sludge volume can be basically reduced by more than 90% in one month, making subsequent removal and treatment simpler.
Wide application: large and small wastewater treatment projects and sludge dewatering projects can be used.
Scope of application of the technology
1 Ecological restoration: the silting of polluted bottom mud in rivers, lakes, reservoirs, seaports, terminals, etc. and the subsequent disposal;
2 Municipal sludge treatment (waterworks and sewage plants sludge), industrial sludge treatment (chemical, pharmaceutical, printing and dyeing, etc.);
3 Wastewater treatment for agricultural, livestock and fishing farms, wastewater treatment for farms, and waste treatment for aquaculture beds;
4 Powder coal ash and low ash treatment in power plants, sulphur desulfurization and dusting sludge in steel plants, sludge treatment in aluminum plants and ceramic plants, etc.
5 Wastewater treatment and waste recycling in mine mining and mining, dewatering of liquids in construction, etc.;
Comparison of technical methods for groundwater dewater treatment
Traditional natural dewatering of mud dumps: This method disposes of the bottom mud of a reservoir, the technology is simple, the area is relatively large, and is
The common method used in domestic mud treatment projects, including the clean-up and treatment of the Tai River mud, is to be found. But the effectiveness of this method of dehydration
The rate is very low, and there are certain environmental and safety risks associated with this method of handling contaminated sludge at the dump.
Because the bottom mud in the dump is bare and in direct contact with the surrounding environment, if the residual water treatment in the dump does not meet the standards, it will
It causes secondary pollution of the surrounding water.
Mechanical dehydration method: Treatment of organic pollution and heavy metal pollution substrate, although the dehydration effect is good, but storage
The one-time investment in equipment is high, the power energy needs to be consumed, the workshop buildings are built, and the processing capacity cannot meet the reservoir.
The requirement for short site-level sludge treatment is inadequate.
Therefore, faced with the implementation needs of large-scale reservoir bottom drying treatment and the difficulty of disposing of bottom mud at traditional dumping sites,
There is an urgent need to find new and viable technologies and methods for sludge disposal. At present, earthwork pipe bags are contaminated abroad
Groundwater dewatering is widely used in groundwater dredging projects such as those in Tianjin, China. Wuhan’s Xisha River sludge removal project, New China Tianjin Eco City Sewerage Reservoir treatment project, and the sludge treatment project of Taihe Wuxi section is used and has good results. Its dewatering process is economical, simple and efficient, and is very suitable for domestic bottom mud disposal projects of rivers, rivers and reservoirs.
