求翻译：这种工艺在结晶和离子交换过程中要使用大量的硫酸调节发酵液和母液的pH，造成环境污染；将味精废水这样高浓度的有机废水，当成“废水”处理，运行费用高而经济效益低。在技术上和经济上是不合理的。所以开发一种既有经济效益，又有环境效益的谷氨酸提取无污染工艺即清洁生产工艺就有很大的现实意义是什么意思？

This process in the crystallization and ion exchange process to use a lot of sulfuric acid to adjust the ph of the fermentation broth and the mother liquor, resulting in environmental pollution; monosodium glutamate wastewater with high concentrations of organic wastewater, as a "waste" to deal with

This process in crystalline and ion exchange process that you want to use a lot of fermented liquid sulfuric acid and adjust the pH mother liquor, resulting in environmental pollution; monosodium glutamate wastewater will be such a high concentration of organic wastewater, treated as "waste" disposa

This craft must use the massive sulfuric acid adjustment fermentation fluid and mother liquor pH in the crystallization and the ionic exchange process, causes the environmental pollution; The monosodium glutamate waste water such high potency organic waste water, regards as “the waste water” process

This process in crystalline and ion exchange process and regulation to use large amounts of sulfuric acid in fermentation broth of mother liquor pH, causing environmental pollution; such high concentration organic wastewater of monosodium glutamate wastewater, as "wastewater" treatment, low running
