The COD,ammonia nitrogen and turbidity of secondary effluent can be farther removed by aerated filter and the reclaimed water qualities are improved.

好气滤池同时具有普通滤池和曝气生物滤池的优点，能对二级出水中的COD、氨氮和浊度等指标进一步去除，提高再生水水质。

Aerobic filters have the advantages of both common filters and biological aerated filter. The COD, ammonia nitrogen and turbidity of secondary effluent can be farther removed by aerated filter and the reclaimed water qualities are improved.

好气滤池同时具有普通滤池和曝气生物滤池的优点，能对二级出水中的COD、氨氮和浊度等指标进一步去除，提高再生水水质。

A process for treating the sludge generated by alumina sewage treating system incldues such steps as pumping the alumina sewage in sand depositing pool then in depositing pool, mixing the bottom sludge, the sewage from sand-water separator, and the regenerated water from filter to obtain backflush water, heating in desilicating heater, washing the secondary red mud to recover Na2O and Al2O3, anjd returning the washing liquid containing Na2O and Al2O3 back to the flow of production of alumina.

本发明公开了一种氧化铝废水处理系统的污泥处置新工艺，它将氧化铝废水先进入沉砂池中进行沉砂处理后才进入沉淀池中，将虹吸泥机从沉淀池中吸出的底流污泥和砂水分离器分离出的污水以及将部分经过滤器过滤后所得的再生水作为反冲洗水一起通过污泥泵送到脱硅加热器中加热得污泥热水，然后将污泥热水用于二赤泥洗涤沉降，以回收赤泥附着的Na2O和Al2O3，将洗涤赤泥后含有Na2O和Al2O3的洗液送到氧化铝生产流程中重新使用。

In addition, reasonably use reclaimed water resource and develop scientific agricultural measures can effectively pervert soil salification and basification.

此外，合理利用再生水灌溉以及制定科学的农业措施能够有效防止土壤盐碱化。

This thesis also discusses the method and water quality according to thesustainable development strategy. It also introduces the using method ofrejuvenated water on agriculture and the trend in the artificial everglade aswell.

本文同时根据可持续发展的思路，着重论述了再生水的利用途径、水质保证等方面的内容，并介绍了具体再生水用于农业的方法和人工湿地研究的进展情况。

Advanced step-water heating layer by layer settles successfully problem of mixing of boiled and unboiled water of traditional single tank heater*and at the same time gets rid of huge body, low-efficient heating, water-leaking, non-heating, unboiled water mixing of multi-tank heater.

先进的步进逐层加热技术有效解决了冷热水混合问题，避免了传统单箱式开水器生水混入的问题和多箱式开水器体积庞大、加热效率不高、浮球阀控制不可靠造成的漏水、不加热、生水混入等难题。

The research result showed that(1) The reclaimed water used didn't influence the sensory quality of a given turf grass tested;under irrigation of reclaimed water,Festuca arundinacea are the best,followed by Buchloe dactyloides and Zoysia japonica;(2) The influence of different types of irrigation water on growth characters of turfgrass is species-dependence;(3) Irrigation by reclaimed water and fresh+reclaimed water increases Na~+,CEC,and total porosity of the turf soil in comparison to fresh water,and improves soil quality.

结果表明：本研究使用的再生水对所供测试绿化草种的颜色、覆盖度、质地和均匀性无不良影响，再生水灌溉条件下，高羊茅表现出了最强的综合耐污能力，其次是结缕草和野牛草。灌溉水类型对于草坪草的生长指标的影响具有种的特异性。再生水灌溉和&清水+再生水&交替灌溉提高了土壤的阳离子交换量和总孔隙度，有利于土壤物理性状的改善。

As the shortage of water resource is seriously,reclaimed water has been used on turf as substitute of fresh water.3 types of water(fresh water,fresh+reclaimed water,and reclaimed water)were used to irrigate 5 common turfgrasses(Poa pratensis,Festuca arundinacea,Zoysia japonica,Buchloe dactyloides,Radix liriopes) during 2003-2005;the growth characters and sensory quality of turf grasses and soil responses were investigated.

随着城市绿地与人争水的问题日益突出，再生水作为替代水资源在草坪草上的应用日益广泛。本试验于2003-2005年用3种类型灌溉水(清水、&清水+再生水&、再生水)处理5种草坪草(草地早熟禾、高羊茅、结缕草、野牛草和山麦冬)，从观赏品质和生长指标方面进行耐污性评价，并分析再生水对土壤的影响。

Results Inbreathe and dermal exposure to THMs in reclaimed water were the main ways of exposure for occupational worker and general populations in road clearing and public garden virescence in Beijing.

结果 再生水中氯仿、一溴二氯甲烷、二溴一氯甲烷、三溴甲烷的浓度分别为0.875~108、0.06~11.0、未检出～5.82、未检出～3.04μg/L。再生水回用于道路压尘、公园绿化，人群通过吸人和皮肤两种途径暴露于再生水，吸人暴露为主要途径，其消毒副产物THMS中。

During the course of building model, considering practicalrequirement qualification, this text has arranged recycling water requirement order and realized preferable supply strategies in the condition of lack water. According to requirements, the same kind water use is optimized. Optimized scheme build five linotyped plan models, which achieves total perfect of recycling water recourses.Geography information system has offered the revelation, storage, analysis and management of space datum.

在建立模型的过程，充分考虑到结合实际的需求条件，将再生水的需求类型排列次序，在再生水供给不足的条件下，实现优先供给策略，对于同类型的用水还要根据其用水地大小和需求量多少再进行优先供给，优化配制共建立了五套线性规划模型，五套模型的组合使用较好的实现了再生水资源的总体优化。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
