Struggling with "blue ice"
Recently, at the Peace Hotel (City. Xining), Department of Science and Technology organized a scientific conference around solving the problem of water hyacinth proliferation packed on the Vam Co Dong River. Many ideas in many different angles were presented, showing hyacinth problem no longer own fear anyone.
Hyacinth on the Vam Co Dong River, running through the town of Dau.
Rep Co. VMC Xining called hyacinth on the Vam Co Dong River as "blue ice" and proposed salvage finished hyacinth, split into three categories: root used as organic fertilizer, building materials themselves do unburned leaves can cause microbial organic fertilizer or animal feed. The company representative said, this is the optimal solution, ensuring harmony between the benefits and costs during the implementation of the contract between the government Xining Company.
Representatives Corporation Global Renewable Energy (GRE) - investment enterprise application deployment process technology, recycling, renewable energy from hazardous waste and medical waste for that can be turned into compost hyacinth solid and liquid fuel, desiccant, animal feed, fertilizer and biogas leaves. The company confirmed that this solution has a highly modern and in sync, save time, solve one part fertilizer for fields, livestock feed, renewable energy and environmental improvements.
Meanwhile, representatives of the University of Natural Resources and Environment City. Ho Chi Minh proposed solution: water hyacinth after salvage, was transferred to the device automatically cut the desired size, mixed with microorganisms and other materials to ensure a balance of moisture and nutrients for microbial production of agricultural service. This technology is low cost, can be applied in practice for all canals in the country.
Particularly representatives from the Institute of Southern Studies says irrigation, water hyacinth on the Vam Co Dong River is the source of methane generation potential enormous. With very rapid growth, large biomass hundreds of thousands of tons, which is also organic materials critical for the manufacture of biogas and electricity production.
Associate Professor Dr Phung Chi Sy of the Institute of Tropical Technology and Environmental Protection and Mai Pham Duy Thong masters of the Center for Environmental Technology to fond of the idea of producing handicraft from water hyacinth. According to Sy, hyacinth weaving fine arts in the Mekong Delta have started to stabilize, but the lack of raw materials. Xining to organize people to go cut hyacinths sold to establishments producing handicrafts in the West. In the long run, Xining should form the hyacinth weaving village. To do this, he plans to donate Sy: "To hyacinth weaving standards, should use wireless systems, zoning hyacinth stakes on both sides of the river. This method also works to reduce riverbank erosion and streaming for easy navigation. "
While many units and individuals in favor of the idea of using water hyacinth as a natural resource, is Professor, Dr. Nguyen Van Phuoc Institute of Environment and Natural Resources City. Ho Chi Minh City are interested in finding methods of limiting hyacinth proliferation. He said that the main cause of invasive water hyacinth on the Vam Co Dong river and canal system in the province of Tay Ninh is caused by domestic waste water, livestock, industrial production and processing of starch tapioca, rubber, sugar cane waste into rivers and streams. The waste is increasing organic content and nutrients in the water, creating conditions for algae and hyacinth grow. To solve this problem thoroughly, the most important is the need to focus on treating pollution and water pollution restrictions. Dr. Phuoc also presents a method of wastewater treatment household activities, wastewater from swine lagoon wastewater tapioca starch, rubber and suggested the State management agencies strictly canals .
Hyacinth been people Xining purchase handicrafts made.
Three doctoral Le Khac Hoang, Dang Thien and Nguyen Thi Hong Loan from Ho Chi Minh City University of Agriculture and Forestry. Ho Chi Minh comments should handle hyacinth with biological measures. The authors of this presentation, there are two species of beetles, but the world is used for biocontrol very effective hyacinths and N.eichhoniae N. bruchi. Both insects were imported from Thailand, Florida (USA), breeding and release into the natural environment to control water hyacinth from 20 years ago. Representing the group, said: "From the results of research in many countries around the world on the use of natural enemies to control water hyacinth shows, this solution has the potential to contribute to the work of prevention and hyacinth control. This measure long-term effectiveness of technical as well as economic, and minimize environmental impact than chemical methods ".
At the conference, there were many other speeches. Each presentation are a scientific research project full of enthusiasm. All the staff are the responsibility of the Ministry of Science and Technology, Department of Science and Technology in Tay Ninh province recorded to research and verify the feasibility before deciding to apply in practice.
Over the years, Xining still struggling hard with remedies Vam hyacinth on the river, as they went about teaching chase downstream collectors hyacinth stalks to produce handicrafts, organized salvage ... which costs money and labor. However, all is not showing the desired effect. Currently, "blue ice" hyacinth still compete daily hourly proliferate, performance, John got together, covering the surface of the river. This situation has caused a lot of problems for waterways, causing damage to agricultural production, especially in aquaculture in the river. Farmers still waiting eyestrain really an effective measure that was born to help them remove the problem was caused by water hyacinth.
