磷复肥污水封闭循环利用技术研究

Phosphatic Fertilizer Production Process Waste Water Closed Recycling Technology Research

磷复肥生产过程中要产生大量的污水,且含有磷石膏,且含有磷石膏、磷酸和氟化物等,直接排放,不仅会引起水资源和农田的严重污染,而且石膏还会堵塞沟渠。另外,污水中所含的污水中所含的P2O5也随之流失,造成资源浪费。因此,污水的治理,直接关系到环境保护与企业的经济效益。

Produce large amounts of sewage containing phosphorus gypsum, phosphate to phosphate and compound fertilizer production process, And and fluoride etc, The direct discharge, Not only will cause serious pollution of water resources and farmland, And the plaster will jam conduit. In addition, Contained in the effluent of P2O5 also will be lost, resulting in a waste of resources Therefore, sewage treatment, directly related to environmental protection and the economic benefit of enterprise.
