The stone industry is a characteristic industry of Rizhao City, which has contributed to the development of the town economy. However, in the process of stone processing, environmental pollution is inevitably caused, especially the water quality of Rizhao Reservoir. Over the years, the party committees and governments of the Rizhao City and the environmental protection departments have actively explored the long-term mechanism for the comprehensive management of the stone industry, achieving a win-win situation for economic benefits and environmental protection.
The waste water and sawing mud generated during the processing of stone will be polluted without any treatment, which will pollute the water source and destroy the use of the land. At the beginning of the development of the stone industry, the vast number of industrialized households did not understand or cooperate. As the concept of environmental protection became more and more popular, the party committees and governments of the various levels and the environmental protection departments unremittingly educated, managed, and guided the majority of business households from passive governance. Actively manage and consciously carry out stone pollution control.
Dong Yanping, a stone processing industry in Wulian County, said that at the beginning, we didn’t know the truth. I don’t know what it’s like, but what is the water, as long as you can earn something, you can do it, but after this. In the past few years, the city and county environmental protection departments and the local party committee and government have correctly guided, now the big guys clearly understand that the pollution of stone is no longer governed, then how our next generation, future generations live in this space, our green mountains and green waters What to do, now we all take the initiative to cooperate with our environmental protection department, so that the stone pollution is not discharged, zero emissions.
There are 889 stone processing enterprises in the street town of Wulian County, with an annual processing of 30 million square meters of plates, which is the main industry in the area. In order to ensure the healthy development of this pillar industry, and to protect the local natural ecological environment, the town party committee government has increased the control of stone pollution, strictly required the stone industry households to produce according to environmental protection requirements, and guide the processing industry to change production methods. Scale and intensive development, reduce the production of solid waste and production water consumption, further transform the concept of development, focus on the development of environmental protection, and unremittingly carry out comprehensive management.
Wu Lixian, the town manager of Wulian County, said that with the support of the municipal and county environmental protection departments, the comprehensive management of the stone industry in the street town has achieved two changes. One is the change from regulation to demonstration, and the households are transformed from passive governance. For the purpose of active governance, the second is to change from simple palliative to standard and cure, and jointly developed flocculant with Fuzhou University, and jointly developed new equipment and new technology such as sawing filter press with Shandong University. Flocculant can effectively solve water and saw. The separation of the mud and the sawing and pressure filter can realize the recycling of water and ensure the timely removal of the sawing mud. Through rectification, the town's rivers have been maintained as a national first-class water quality standard for three years, and wastes such as sawing saws have been recycled effectively.
In the comprehensive management of pollution in the stone industry, Chenye Town of Donggang District adopts a market-oriented operation method to carry out centralized transportation and centralized treatment of wastes such as sawing mud produced by processing.
Qin Yuhe, director of the Stone Management Committee of Chenjing Town, Donggang District, said that in the pollution remediation of the stone community, while doing a good job in comprehensive environmental improvement, we also focused on the work of sawing and cleaning the mud. At the beginning of the year, we set up through social bidding. The sawing and mud removal company is responsible for the sawing and mud removal company, and uniformly clears the saw mud waste generated by the entire stone community, clears it to the fixed storage place, and uniformly processes it. This avoids the stone industry households from cutting the mud residue. The chaotic phenomenon of chaos, so that the stone community environment has been fundamentally improved.
FLD Type aluminum armor rod is mainly used in overhead transmission and distribution line construction for purposes such as binding conductors to insulators, field assembly of aerial cable, and for armoring conductors subject to excessive wear.
When busbar is connected with different type bolt strain or suspension clamps, it must wrap Aluminum Armor Tape, direction of winding spreading towards the outer aluminum strands. The exposed outlets of the two ends should be less than 10mm while the outlets must be gripped into the clamp; aluminum armor tape needs to be wound evenly on the over 3cm position between the bound ceramic insulator parts. The binder deserves to be selected as equivalent model conductor on which the middle part of binder is used for wrapping the conductor along the two sides of ceramic insulator in the bottom-up processing, respectively; until the two ends of binder returns to the opposite positions of ceramic insulator as crossover, then up to the opposite once again through bottom to up winding.
