请翻译另外在其他文件规定方面《船舶水污染防治技术政策》中将生活污水分为黑水和灰水两类其中灰水包括来自洗碗水、厨房水槽、淋浴、洗衣、洗澡池和洗手池下水道的排水不包括来自货物处所的排水。并同时要求应逐步实施灰水管控。、在饮用水水源保护区等不得排放生活污水的水域内应采取将生活污水收集储存在船上相应装置内并关闭排水阀等控制措施防止生活污水进入环境水体并按规定对相关控制措施进行记录。但该文件仅为指导性文件缺

In addition, in terms of other file regulations, the "Technical Policy for Ship Water Pollution Prevention and Control" classifies domestic sewage into black water and grey water. Grey water includes wastewater from dishwashing, kitchen sinks, showers, laundry, bathing tubs, and hand basins, excluding wastewater from cargo areas. It also requires the gradual implementation of grey water control and the adoption of control measures such as collecting and storing domestic sewage on board in corresponding devices and closing drainage valves in water areas where domestic sewage is not allowed to be discharged, such as drinking water sources protection zones, to prevent domestic sewage from entering the environment water bodies. Furthermore, it stipulates that records should be kept for relevant control measures. However, this document is only a guiding document and lacks legal enforceability.
