1.0.1 The code is formulated to implement national water resources saving and environment protection policies, promote the cyclic utilization of industrial cooling water and the sewage reclamations, effectively control and reduce all sorts of harms caused by re-circulated cooling water, guarantee the recuperation efficiency and service life of implements, decrease the water pollution and enable the industrial cycle cooling water treatment to be state-of-art, economical and practical, and secure, stable.
1.0.2 This code is applicable to newly-built, expanded and re-built re-circulated cooling water treatment designs which adopt surface water, groundwater and reuse water as make-up water.
1.0.3 Industrial cooling water treatment design should correspond with demands such as production safety, environment protection, energy conservation and water saving, and is facilitated to carry out construction, maintenance and operation management.
1.0.4 Industrial cycle cooling water treatment design should introduce state-of-art productive practice experience and scientific payoffs and adopt new technique positively and prudently.
1.0.5 Industrial cycle cooling water treatment designs should correspond with relative national current standards and specifications, besides this code.
