[Previous technical standards] . < Traditionally, the clean water treatment process is mostly coagulation: and the settlement process is used for each sequence, and the design standard of the child drop unit is based on the original water turbidity of two thousand degrees. Within 100% of the water, if the turbidity reaches 5,000 kWh, it is necessary to strengthen the pharmacy. The amount of water is only about 85 percent. When the turbidity is 5,000 to 10,000 kWh, the amount of water is reduced to 80%, and about 10,000 degrees. Only 50% of the water can be discharged, and only 10% of the 15,000 or more, and when the water output is only 75% to 85%, the partition is required: water supply, which has a considerable impact on people's livelihood or industry.
