可以的话就给我分
谢谢哈

Adopt the embrane method to wash the waste water and deal with second to the printed substrate, in the hope of reaching surfacinging accord with the standard of retrieval and utilization of normal water, reduce the heavy metal ion to pollute, it is the purpose that the producer saves the expenses of water. Regard entering the water flow, producing water rate as condition, study, strain a little - to normal water water quality reverse osmosis - second reverse osmosis, strain a little - receive, strain - reverse osmosis two technological process.仅供参考

Adopt membrane method to carry out two stage treatment on printed substrate irrigation waste water, to look forward to reaching out water according with middle, water returns to with the standard , cuts down the heavy metal ion contaminate, be that the manufacturer economizes the purpose using water to expend. With water-entering rate of flow , product water rates as a precondition, have studied decline to filter- the reverse osmosis- two stage reverse osmosis , decline filter- accept the effect filtering- reverse osmosis two kinds process flows centring water water quality.

A membrane on the printed circuit board washing wastewater secondary treatment, with a view to comply with effluent standards in the water reuse, reduce heavy metal pollution, save water for the factory expenditure purposes. To water flow, water production rate of conditions on the micro - reverse osmosis - two reverse osmosis, microfiltration - NF - the two reverse osmosis water quality in the process of the impact.
