At present, my country's domestic waste exceeds 270 million tons every year and is increasing year by year. Against the background that traditional single facility methods are prone to frequent mass incidents, Shanghai, Beijing and others regard solid waste disposal bases as major livelihood projects and national ecological civilization construction to solve the problem of garbage siege. Since 2001, the project team has carried out major scientific and technological research in the field of energy and environmental technology, relying on the Laogang base, which covers an area of more than 29 km2, serves more than 14 million people, handles more than 60% of Shanghai's garbage, and ranks first in the world in terms of total facilities. Breakthrough international advanced innovation results. 1 Scientific and technological innovation (1) Key technologies for intensive conservation of landfill land in ultra-large solid waste bases, overcoming the problems of low landfill height of soft soil foundations with mudflats defects and serious land waste. Innovatively designed technologies such as static load pressurized and strong drainage foundation reinforcement, lateral tube well interlayer drainage, and foundation vertical settlement-horizontal displacement monitoring. The landfill height has been increased from 22m to 47m, and the storage capacity utilization rate has been increased by 67%; Developed ecological restoration and utilization technology for old landfill sites, and graded utilization of stabilized sites with low, medium, and height rdquo; 3.34 million m2. Significantly improve the comprehensive performance and use efficiency of land. (2) Key technologies for intelligent and efficient clean energy in ultra-large solid waste bases to overcome the problems of single energy utilization and low efficiency. The first Venturi self-circulation negative pressure drainage and gas collection integrated technology has increased the landfill gas extraction efficiency by more than 20%, innovatively designed gas-electricity-heat cogeneration technology, and cogeneration efficiency of 84%. Developed a new type of grate containing rare earth metal RE for strong air distribution, the first flue gas recirculation low-air ratio combustion-wet GGH heat exchange process, and the first to build a single-furnace 750t/d, the world's first 9000t/d waste incineration plant; Created a multi-dimensional clean energy complementary intelligent dispatch technology, ldquo; wind/light/biogas/incineration heat energy rdquo; complementary utilization of 297.5MW. The annual electricity consumption on the Internet is more than 500 million kilowatt-hours. (3) Key technologies for efficient cleaning of secondary pollution in ultra-large solid waste bases, overcoming the problem of pollution ldquo; compounding and amplification rdquo; effects. The first technologies such as anaerobic reactor-regulation tank linkage multi-source conditioning, low reflux ratio and low hydraulic retention time efficient denitrification, and nanofiltration-two-stage material membrane-two-stage reverse osmosis zero-moving concentrate to achieve high-concentration mixed leachate water reuse and zero emission; invented microbial inoculants source odor suppression and refined landfill technology for minimum working area, developed mobile capture equipment and heat storage purification equipment to achieve a strong reduction of more than 70% in large-area unorganized odorous gas sources. (4) Key technologies for green and intelligent management of ultra-large solid waste bases, and overcome the outstanding problem of the proximity effect of solid waste facilities. It pioneered a new strategic paradigm for solid waste facilities in megacities, providing significant support for the construction and operation of world-class old port bases; built ldquo; internal online monitoring, 1km professional feedback, 8km public perception rdquo; odor monitoring and response network, developed material and energy collaborative interaction and intelligent control technology to achieve horizontal ldquo; base-community-public rdquo; risk three-party interaction, and vertical ldquo; enterprise-district-municipal bureau rdquo; information three-level linkage. 2 There are 96 intellectual property invention patents and 115 utility models. Standards and specifications: 9 national, 48 industry, 6 local, 32 monographs, and 411 papers (including 124 SCI/EI);11 innovative achievements have reached the international advanced level. 3 Apply and promote a large number of original world-class technological achievements and fully use them in the Laogang super-large solid waste base, ensuring the safe, orderly and efficient operation of Shanghai's city; promote them to 10 provinces and cities including Chengdu, Nanjing, and Qingdao, serving 76 million people., The amount of garbage is 74,000 tons/day. In the past three years, the new output value has been 8.2 billion yuan and the profit has been 1.3 billion yuan, with significant social and economic benefits. It has led the development of solid waste technology in my country and made significant contributions to the construction of ecological civilization in my country.
