污泥处理处置是排水行业面临的严峻挑战之一。如若处理不当，不但会浪费污泥中所蕴含的资源和能源，还会产生新的环境污染。项目立项之初，我国80%以上污泥未得到有效处理，污泥处理技术落后于发达国家，缺乏适合我国泥质特点的处理技术。污泥定量化技术缺乏，污泥处理设施无法准确设计；污泥减量化技术缺乏，大量污泥随意堆放；污泥资源化技术缺乏，污泥中资源和能源大量浪费。为破解我国污泥难题，亟需开发符合我国污泥特点和经济技术水平的污泥处理技术。

Sludge treatment and disposal is one of the most serious challenges that the drainage industry faces. If the sludge was improperly disposed，not only would the resources and energy contained be wasted， but would also cause new environmental pollution. In the beginning of this project，more than 80% of the sludge was not treated effectively in China， while thesludge treatment technologies lagged behind those of the developed countries， and did not suit the sludge characteristics of our country. As the quantitative technology of sludge production was unavailable， sludge treatment facilities couldn’t be designed accurately; as the sludge reduction technology was unavailable， a large amount of sludge was piled up carelessly; and as the sludge utilization technology was unavailable，lots of resources and energy contained in the sludge were wasted. To solve the problem， there was a pressing need to develop sludge treatment technologies that suit the sludge characteristics and economic and technological level in China.

建立适合国情的污泥产量计算模型

Building the Sludge Production Calculation Model That Suits Chinese Situations

首次建立适合我国国情的初沉污泥和剩余污泥产量计算模型，通过历时3年的中试研究和对100多座污水处理厂的运行数据分析，揭示了水温、污泥龄、污泥负荷等关键因子对模型参数的交互影响规律，率定了多工况条件下模型参数典型值，开创性地解决了我国污水处理厂污泥产量预测不准确的技术难题，项目成果被我国国家标准《室外排水设计规范》引用。

The calculation models of primary sludge and secondary sludge production that suit Chinese situations were built for the first time through three-year pilot study and the operational data analysis of more than 100 waste water treatment plants. The interactive effects that key factors such as water temperature， SRT， sludge loading had on the model parameters were revealed， and typical values of the model parameters under different operating conditions were quantified. The problem that the sewage treatment plants in our country faced in sludge yield forecast was successfully solved， and the project achievement was cited in China’s national standard Code for Design of Outdoor Waste water Engineering.

首次将电化学处理引入污泥调理预处理，解决了污泥脱水驱动力不足的技术难题，获取了最佳电解电压、电解时间和电极板间距等核心工艺参数，显著提高了污泥的脱水性能。首次将Fenton试剂引入污泥调理，发明了一种污泥高效低耗深度脱水方法，解决了污泥水分结合形态破解困难的技术难题，形成了基于泥质特性的Fenton试剂与铁盐、聚丙烯酰胺、聚合硫酸铝等复配调理的系列技术和最佳参数。(www.xing528.com)

Electrochemical treatment technology was introduced into sludge pre-treatment field for the first time， and the problem of driving force insufficiency solved. Optimal parameters， such as electrolytic voltage， time and electrode gap were quantified， and the dewatering performance of sewage sludge was obviously improved. Sludge deep dewatering process of high efficiency and low consumption was invented by introducing Fenton reagent into it， and the problem of water combination form breaking was tackled， while a series of technologies and optimal parameters based on the sludge characteristics were researched of compounding Fenton reagent and ferric salt，polyacrylamide， polymer aluminum sulfate.

The integration technology of effectively utilizing sludge biomass was developed， and the negative influence that sands had on anaerobic digestion efficiency was eliminated though the development of sand and dreg removal technology and equipment， removing more than 90% of the sand with the size bigger than 2 mm. Through the development of anaerobic digestion technology for high-solid content sludge as well as sludge and organic waste co-digestion technology， bio-gas production was improved by more than 60%. Through the development of biogas desulfurization technology， H2S content in the bio-gas was reduced to less than 5 mg/L， thus significantly improving the bio-gas quality.

随着我国城镇化进程的加速，污水处理量日益增加，污水处理过程伴随产生的污泥量也急剧增加，污泥处理处置已成为污水处理厂面临的严峻挑战之一。该项目研究成果具有重要的工程实用价值，不仅可以指导污泥处理系统的科学设计、运行和管理，而且还可以指导污泥的减量化和资源化利用。项目研究成果还可以在上海和全国其他地区进一步推广应用，为污水处理厂污泥减量化和资源化利用提供技术支持，具有广阔的成果发展或转移化前景。

With the acceleration of urbanization process in China， the sewage quantity is increasing sharply， which brings along more sludge production; therefor， sludge treatment and disposal has become one of the most serious challenges that the drainage industry faces. This research project’s results have important practical engineeringvalue， which can not only guide the scientific design， operation and management of sludge treatment system， but also be helpful to sludge reduction and utilization. These results are supposed to be further applied in Shanghai and the rest of China， and to provide technical support for sewage plants’ sludge reduction and utilization， which will have broad transformation and development prospects.
