According to the statistics of China Iron and Steel Industry Association, the comprehensive utilization rate of solid waste in Daqiuzhuang Spiral Pipes and key steel companies in China is over 95%. The solid wastes such as Spiral Pipes and Steel Slag in Daqiuzhuang are mainly used for sale and building materials. Zhuang spiral pipe, solid waste disposal process management and utilization level need to be improved urgently. Daqiuzhuang spiral pipe, solid waste utilization technology innovation and standard system need to be strengthened, Daguozhuang spiral pipe, comprehensive resource utilization industry standardization and large-scale development level needs to be improved . The specific performance is:
Not enough attention, Daqiuzhuang spiral pipe, iron and steel enterprise solid waste utilization management level needs to be improved. Iron and steel enterprises generally have scattered solid waste recycling management and unclear ownership. Daqiuzhuang Spiral Tubes, lack of major solid waste generation measurement facilities, Daqiuzhuang Spiral Tubes, accurate measurement of solid waste generation quantities, solid waste utilization channels and flow, solid waste Supervising the recycling process and incomplete overall management of solid waste utilization projects, etc., Daqiuzhuang spiral pipe, the level of fine solid waste management needs to be improved. For example, the solid waste utilization methods of Japan's steel slag have detailed data statistics, Daeguzhuang spiral pipe, and China has no relevant statistical data. In terms of solid waste statistics and process supervision, companies such as South Korea's Posco, Japan's JFE and China's Baosteel are significantly better than other steel companies. At present, Daguozhuang spiral tube, although China has formulated a preferential tax reduction policy for solid waste utilization products, Daqiuzhuang spiral tube, but the implementation of solid waste utilization product certification and tax preferential policies is difficult to implement. Factors such as low added value and general economic benefits have affected the Daqiuzhuang spiral pipe and iron and steel enterprises' enthusiasm for solid waste utilization and their willingness. At present, although the state has established a sewage discharge permit system and a standard for sewage charges, Daqiuzhuang Spiral Pipe, there is no detailed supervision on the generation and discharge of solid waste. Daqiuzhuang Spiral Pipe, solid waste recovery, storage, transportation, disposal and The monitoring of the final waste flow and other processes is not enough, and the Daqiuzhuang spiral tube causes the solid waste to be dumped and discarded randomly.
The numbers are unclear, and the statistics of solid waste utilization in the iron and steel industry need to be improved. In China, there are more than 500 companies with smelting production capacity and Daqiuzhuang spiral tubes, but the industry association focuses on statistics of only over 100 steel solid waste companies. Daqiuzhuang spiral tubes have a small sample size. Industry statistics mainly include data on solid waste generation, recovery, utilization and utilization. Daqiuzhuang spiral pipe, solid waste utilization methods and utilization technology statistics are relatively lacking. Daqiuzhuang spiral pipe cannot monitor the final flow of solid waste. Compared with the situation of different solid waste utilization technology projects, the Daqiuzhuang spiral pipe is not conducive to comprehensive analysis and grasp of the solid waste utilization situation of the iron and steel industry. In addition, Daguozhuang spiral pipe, solid waste statistics are mainly reported by enterprises, and Daguozhuang spiral pipe, the authenticity of the data and the understanding of statistical caliber are also uncertain.
Technical bottlenecks, Daqiuzhuang spiral pipe, steel waste solid waste utilization technology level needs to be improved. At present, Daqiuzhuang spiral pipe, the steel industry's research on solid waste source reduction technology is not deep enough and not systematic enough. Daqiuzhuang spiral pipe, the standardization of solid waste disposal and harmless treatment are not detailed enough. Problems such as single solid waste resource utilization technology, low added value of products, and shortage of low cost and efficient solid waste utilization technology. For example, Daguozhuang spiral pipe, steel slag and other bulk solid waste utilization are mainly concentrated in the construction areas such as manufacturing building materials products, engineering backfilling and paving. Daguizhuang spiral pipe is affected by factors such as the limited downstream building material market and sufficient raw material sources. However, the iron and steel slag in the western region of China is generally in a state of storage and cannot be used for resources. In addition, Daqiuzhuang spiral pipe, the solid waste utilization technology research and development and promotion of the promotion mechanism is not perfect, Daqiuzhuang spiral pipe, the industry-university-research connection is not close, Daqiuzhuang spiral pipe, related technology, equipment standards, product standards construction lagging and technical evaluation standards The lack of Daqiuzhuang spiral tubes makes it difficult to support the promotion and application of advanced technology and equipment.
Industry barriers, Daqiuzhuang spiral pipes, and the coordinated development of upstream and downstream solid waste utilization need to be strengthened. The solid waste utilization of the iron and steel industry has a wide range of characteristics and obvious industry crossover characteristics. Daguozhuang spiral pipes have significant cross-sections with downstream building materials, nonferrous metals, chemical industry, agriculture and other fields. Daqiuzhuang spiral pipes, especially steel slag in the field of building materials Resource utilization. But currently there are generally poor upstream and downstream connections, technical barriers and qualification barriers between different industries, Daguozhuang spiral pipe, upstream solid waste utilization technology, product and equipment standards that overlap, cross or even conflict with downstream, Daguozhuang spiral pipe, and upstream Solid waste utilization products are not recognized downstream.
In addition, in Daqiuzhuang spiral pipe, the solid waste utilization of the iron and steel industry in China still has the problems of small scale, scattered operation, and low industrialization level. The number of Daqiuzhuang spiral pipe, leading, backbone and pillar enterprises is relatively small. In particular, the solid waste utilization technology research and development, promotion, and equipment industrialization are insufficient. The Daqiuzhuang spiral tube has become an important factor restricting the standardized and large-scale development of the solid waste utilization industry.
