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。

The preparation process includes the following steps: dissolving activator and RE oxide in the molar ratio of 0.01-0.02 in concentrated nitric acid and heating to dry, dissolving the obtain RE nitrate in deionized water to obtain solution of RE nitrate; dissolving soluble tungstate and surfactant in deionized water to obtain tungstate solution; mixing the RE nitrate solution and the tungstate solution through stirring to reaction for 25-60 min to obtain white precipitate; hydrothermal reaction of the precipitate in a reaction kettle at 100-260 deg.c for 24-72 hr; centrifugally separating, washing and drying to obtain the product.

浓硝酸的加入量保证稀土氧化物溶解就可以，过量的硝酸可以加热除去；将可溶性钨酸盐和表面活性剂溶解于去离子水中，得到钨酸盐溶液，表面活剂性的加入量为反应原料重量的0-30wt％；将稀土硝酸盐溶液加入到钨酸盐溶液中搅拌，发生沉淀反应，磁力搅拌时间为25-60分钟，得到白色沉淀；将含有沉淀物的溶液作为前驱物加入到反应釜中，发生水热反应，反应温度为100-260℃，反应时间为24～72小时；离心分离，洗涤，干燥，即得所需产物。

Taking the irrigation with reclaimed water of Dawukou Forest Park in Ningxia as an example, through the indoor test of one-dimensional dust columniation , the regular patten of pollutant shift in soil when irrigated with reclaimed water at different infiltration condition was studied.

摘要以宁夏回族自治区大武口市森林公园利用再生水灌溉为例，通过室内一维土柱试验模拟土壤的入渗过程，研究了不同灌溉入渗条件下污染物在土壤中的运移规律，结果表明：土壤的吸附作用是影响该地区土壤污染物迁移的主要因素。

Working principle is the power that uses water pump to serve as loop and sparge, the one side in gush room or 3 form Shui Lian, sparge is formed inside gush fog chamber, the Qi Wu of the generation when spray paint or burnish or dir

工作元理是使用水泵作为循环与喷雾的前进力，在喷房的一边或者三面产生水濂，在喷雾房内产生喷雾，喷涂或者磨擦时型成的漆雾或者尘士，在强效抽风作用以及影晌下经过水濂时随水势到水池内，剩余的通过喷雾室重新冲冼由排风机抽走，进而使排到室外的空气air达到和实现最好的诘白作用，满意环境保护请求。

The explosion of World War 2 made lots of women worn pants for working. 1960's the third revolution of science and technology developed fast, and the woman's rights become more and more active which made women get the right to wear pants freely.

西方女士裤装在最初只是贵族女性的运动穿着；二战的爆发使大量女性穿上裤子顶替男人的工作岗位；60年代，第三次科技革命风生水起，女权运动也随之活跃起来，使女性完全拥有了穿着裤装的自由。

A combined technology of ' tertiary treatment - ecological purification - in situ remediation' was proposed to reutilize the secondary treatment effluent with assured water quality and ecological safety of the urban rivers.

通过对相关案例和水质标准的分析，阐述深度处理和生态净化对污水景观河道回用的重要意义；提出改善回灌河道水质和确保生态安全的城市污水&三级处理+生态净化+河道修复&工艺；以宁波市南区污水处理厂污水再生回用工程工艺设计为例，从河道水体现状、再生水水质水量、投资与效益及配套保障措施等方面，探讨采用该工艺进行城市污水尾水再生和景观河道回灌，实现生态环境利用的技术经济可行性。
