阐述了水解酸化工艺的机理，介绍了其以独立的工艺或与其他工艺相结合在印染废水处理中的应用，并分析了水解酸化过程中微生物及其产生的胞外酶的作用。另外，本文还总结了水解酸化阶段的优化调控方法，包括直接投加菌剂或共代谢基质类物质和投加激活剂，并概括了水解酸化调控效果的评价指标，包括pH值、色度、挥发性脂肪酸 VFA、BOD5/COD、有机物组成的变化、酶活、微生物种群结构变化。目前，虽然水解酸化工艺在印染废水处理中应用广泛且有所成效，但是对其中微生物的作用机制尚不十分了解，无法有针对性地对功能菌群进行优化调控。本文提出在深入探讨微生物作用机理的基础上，针对功能菌群进行优化调控，是提高水解酸化速率的一个有效途径，从而最大限度地发挥水解酸化工艺在印染废水处理中的作用。

The paper sketched the mechanisms of hydrolytic acidification process,introduced the applications of the independent process or combined with other technologies in dyeing wastewater treatment,and analyzed the roles of microbes and extracellular enzymes in hydrolytic acidification process. This paper also summarized the optimization regulation methods of hydrolytic acidification stages,including adding microbial agents or co-metabolism matrixes and activators. The evaluation indexes of hydrolytic acidification regulation effect were generalized , including pH value , chromaticity,volatile fatty acids (VFA),BOD5/COD,variation of organic matters,enzyme activity and changes of microbial population. Currently,although hydrolytic acidification process is widely used and made some achievements in dyeing wastewater treatment,the mechanisms of microbes in it are still not clear making the specifically regulations of functional microbes difficult. This paper proposed an effective way t

研究蔬菜类废物两相厌氧消化过程中水解酸化液物化性质随水解时间的变化情况,结合总有机碳（TOC）、溶解性有机碳（DOC）、颗粒粒径和溶解性有机物（DOM）分子量的分析,探讨了蔬菜类废物水解酸化过程中TOC溶出和颗粒降解之间的关系,分析了水解酸化相颗粒物降解规律.实验结果表明,蔬菜类废物水解过程可以分成两个阶段：易水解的颗粒物在前5d迅速水解,TOC浓度迅速升高,在第5d达到最大值4920mg/L,水解产生颗粒态物质的二次平均直径从第1d的58.38μm降至第5d的4.64μm,有机物快速溶出,DOC/TOC比值在第4d达到最大值85%,该水解过程可用Contois模型模拟；第5d后,难水解颗粒物质的缓慢水解起主导作用,颗粒态物质的二次平均直径从4.64μm开始逐渐增大,并稳定在8.97~10.68μm范围内,TOC和DOC溶出率逐渐降低,且DOC溶出率小于TOC溶出率.大分子溶解性有机物的降解也主要集中在水解过程的前5d,水解第1d 产生的大分子 DOM（1.6×109~1.9×109Da）到第5d 已经全部降解成分子量在5×104~4×106Da 的DOM；第5d过后,DOM的分子量分布情况并未发生较大变化.表明蔬菜类废物两相厌氧消化工艺过程中水解时间可缩短为5d.

During the two-phase anaerobic digestion process of vegetable waste, changes of hydrolytic acidification liquid’s physical-chemical properties were investigated. The relationship among dissolution of total organic carbon (TOC), dissolved organic carbon (DOC) and particulate degradation was discussed. The mechanism of particle hydrolysis acidification was assessed by combining the trend of TOC, DOC, particle size distribution and molecular weight evolution. The experiment results showed that, the hydrolysis process of vegetable waste could be divided into two stages. In the first five days, particulates with high degree of hydrolysis began to hydrolyze quickly. The TOC value rose rapidly, reaching the maximum of 4920mg/L in the fifth day. The quadratic mean diameter of particulates generated from hydrolysis dropped from 58.38 μm in the first day to 4.64 μm in the fifth day. Furthermore, organic matter dissolved rapidly, with a maximum of 85%DOC/TOC ratio. This process could

With the process of micro electrolysis -hydrolysis acidification -nitrification and denitrification in the treatment of hairwork wastewater, that micro electrolysis removed chromaticity and other pollutants in wastewater, improved the biodegradability in wastewater, to facilitate the subsequent biochemical treatment, and hydrolysis acidification of subsequent processing volumetric loading, improved the efficiency of removing, which had an obvious effect of organic nitrogen in the water ammoniation, nitrification and denitrification can transform all the NH3 -N that produced by the hydrolysis. Running results showed that when the flooding water COD was 1 100 mg/L, ammonia nitrogen was 120 mg/L, the degradation process of COD and nitrogen removal effect was good. The process assuranced system effluent COD<40 mg/L, ammonia nitrogen <5 mg/L, and achieved the primary standard of sewage comprehensive discharge standard.

某污水厂在提升出水标准的工艺调控中,对磷的生物法去除进行了理论分析和实践研究,通过强化水解酸化效果,并对活性污泥在整个生化系统中的分布和循环进行调控后,试验取得了显著的生物除磷效果,当进水TP为4~5 mg/L时,出水TP1 mg/L。实践表明污泥龄并不一定对磷的去除效果有较大影响。在发挥水解酸化作用的基础上,创造条件使活性污泥在整个厌氧和好氧生化系统中充分循环是发挥生物除磷作用的关键环节。

The theory and practice on phosphorus removal were analyzed during the upgrading of effluent standard in a wastewater treatment plant. The results show by strengthening hydrolytic acidification and adjusting distribution and cyclic of activated sludge in the biochemical system,there is a remarkable effect on phosphorus removal. Practice also indicates that sludge age has not necessarily effect on phosphorus removal. Based on the action of hydrolysis acidification effect,to create conditions for the activated sludge to practice full circulation in the biochemical system is the key link on biological phosphorus removal.
