1、概况唐山市是河北省乃至全国的重工业基地之一。目前,全市每年约产生粉煤灰及其它工业废渣2600万吨,累计堆存量已达2.88亿吨。全市九个燃煤电厂年排粉煤灰达300万吨,占全省粉煤灰年排放总量的50％,目前,在建与筹建的燃煤电厂装机容量近百万千瓦,粉煤灰排放量呈逐年上升趋势。由于复建与发展,对建材与墙材需求量大,目前,仅实心粘土砖厂就有366个,占挖地约3万余亩,年产粘土砖约30亿块,年耗标煤达40万吨,再加上开滦的大面积采煤塌陷等给唐山的土地资源及环境保护造成很大的威胁,形势极为严峻。
1. Overview Tangshan City is one of the heavy industrial bases in Hebei Province and even the whole country. At present, the city produces about 26 million tons of fly ash and other industrial waste each year, and the accumulated stockpiles have reached 288 million tons. The city’s nine coal-fired power plants have an annual discharge of 3 million tons of fly ash, accounting for 50% of the total annual fly ash emissions in the province. At present, the installed capacity of coal-fired power plants under construction and preparation is nearly 1 million kilowatts, and fly ash Emissions are increasing year by year. Due to rehabilitation and development, there is a large demand for building materials and wall materials. At present, there are only 366 solid brick bricks, accounting for more than 30,000 acres of excavated land, and an annual output of about 3 billion clay bricks. 400,000 tons, together with the large-scale coal mining collapse of Kaiyuan, pose a great threat to Tangshan’s land resources and environmental protection. The situation is extremely grim.
