With the domestic and foreign advanced oxidizing preconditioning ( it can remove ammonia and nitrogen organic material, humic acid, magnesium and HVM film ) separating technology, it separated solid precipitant from brine so as to obtain purified salt brine. 该工艺采用国内外先进的氧化预处理除氨氮有机物、腐植酸、镁和HVM膜分离技术将反应生成的固体沉淀物从卤水中分离出来,从而得到纯净的盐卤水。
Quickening foaming speed while postponing gel time by bloked amine catalysts with organic acid could improve the foam flowability and shorten the demold time, thus according with the demands of modernized production technology of polyurethane rigid foams. 用有机酸封闭叔胺催化剂,加快了发泡速度同时推迟凝胶时间,可改善泡沫流动性并缩短脱模时间。从而满足聚氨酯硬泡现代化生产的工艺要求。
In mixed organic carboxylic acid solutions, a gray ceramic like film with excellent appearance and higher hardness is obtained on cast aluminum alloy by using electrochemical deposition ceramic film ( EDCF ) technology. 利用电化学沉积陶瓷膜(EDCF)技术将铸铝ZL108合金置于有机羧酸复合体系,制得了具有较高硬度和良好外观的灰色类陶瓷膜。
Waste activated sludge ( WAS ) contains large amounts of organic matter. Hydrolysis and acidification of WAS can reduce the sludge concentration and the production of volatile fatty acid ( VFAs ) can be used as carbon source of biological nutrient removal technology. 剩余污泥中含有大量有机物,其水解酸化过程能实现污泥的减量,同时回收利用酸化产物中的挥发性脂肪酸,用于生物脱氮除磷工艺,能有效解决城市污水碳源不足的问题。
