恩平地处珠江三角洲,人多地少,取土制砖越来越困难,恩城建材厂为此多次搬迁。与其毗邻的氮肥厂,每天排出废渣60吨。其中沸腾炉渣25吨,造气炉渣35吨。十余年来,堆放废渣约20万吨,占农田近百亩,最后,被迫倒入锦江,污染环境。如能利用这些废渣制砖,则可变害为利,一举两得。在有关单位的支持配合下,我们经过两年的试验,直接利用这两种废渣制出强度较好的煤渣砖。恩城建材厂利用废渣制砖的第一期工程于1979年7月投产,日产砖14000块,能把氮肥厂每天的废渣“吃”掉。 Enping is located in the Pearl River Delta, where there are more people and less land, and it is getting more and more difficult to take home bricks. The Encheng Building Materials Factory has moved several times for this purpose. The nitrogen fertilizer plant adjacent to it discharges 60 tons of waste residue every day. There are 25 tons of boiling slag and 35 tons of gas slag. In the past ten years, about 200,000 tons of waste residue was dumped, accounting for nearly 100 acres of farmland. Finally, it was forced to pour into Jinjiang and pollute the environment. If these bricks can be used to make bricks, it can be used as an advantage. With the support of the relevant units, we have used two years of experiments to directly use these two types of waste residue to produce stronger cinder blocks. The first phase project of the Encheng Building Materials Factory using waste residue bricks was put into operation in July 1979, and 14,000 bricks per day were able to “eat” the daily waste residue from the nitrogen fertilizer plant.
