众所周知,在密实砌块生产中,为防止制品表面疏松,需在搅拌时加热水,提高混合料温度。一般加热水量由原材料中粉煤灰及煤渣含水量多少而定,按我厂目前二跨二班制日产700立米计算<每立米需加水100～300公斤左右,则日用水量为70～210吨左右;同时其水需用蒸汽加热到80℃左右。另一方面在我厂加气混凝土制品蒸压养护及密实砌块蒸养养护过程中排出的废水 As we all know, in the production of dense blocks, in order to prevent the surface of the products from being loose, it is necessary to heat the water while stirring and increase the temperature of the mixture. The amount of heating water is generally determined by the amount of fly ash and coal slag contained in the raw material. According to our plant’s current two-span, two-shift daily production of 700 um, each ridge requires about 100 to 300 kg of water, and the daily water consumption is 70 to 210 tons. At the same time, the water needs to be heated to about 80°C with steam. On the other hand, the waste water discharged during the autoclaved curing of aerated concrete products and the curing of dense blocks in our factory
