Reuse world

Today, one of China’s sewage treatment plants are being built like a dry pull onions. Wastewater treatment as a guarantee the water quality, promote water reuse in a good way, has been more and more people are recognized. For the water supply enterprises, sewage treatment market-oriented path is also grown larger in width and has a sewage treatment plant as “throwing a long line to catch a big fish,” characteristics of municipal infrastructure projects in the economic turmoil of the society, has been full of “favor.” For

attendant and sewage treatment sludge, sewage treatment industry will become increasingly high in the “horn sound”, then amplified “dumb dumb.” Policy Research Center, Tsinghua University, director of Water Industry, Dr. Fu Tao with a bit reluctantly said: “China’s current development in the field of sludge treatment is not enough.”

Industry accustomed to call this phenomenon as “light-heavy water mud. “

policy, the cost - both strangling throat

sludge treatment with a large number of organic compounds, a number of dangerous pathogenic microorganisms and heavy metals in sludge, absolutely can not be overlooked. Sludge around the city will turn into secondary sources of pollution, erosion, air, water and soil, its degree of risk of harm is far greater than the water itself.

can not be denied, sludge treatment has its own difficult to break through the “bottleneck”: high-energy, large infrastructure investments and other issues made the cost of sludge treatment continued to rise; Government is facing heavy pressure, sludge treatment policy is not a long time to finalize .

2008 Nian 7 months, sludge draft policy paper on environmental management system and finally in the “Environmental Management System policy paper sludge seminars” on the surface. Uphold the “municipal wastewater treatment plant sludge treatment and disposal guidelines for best available techniques” embodies the direction of mainstream technology, and advanced technologies; “municipal wastewater treatment plant sludge treatment and disposal technology policy” more available and the implementation of mandatory; “Urban Pollution water treatment plant sludge treatment and disposal technical specifications “to play a regulatory role of the market principle, sludge environmental management system policy documents are being further revised and perfected.

a higher moisture content of sludge by mechanical means making a significant reduction of water has become very difficult, using the better-performing heat-treatment method was facing an enormous energy consumption. In addition, the sludge treatment works huge investment. Tianjin Municipal Engineering Research Institute, Zhao Yue, deputy chief engineer of the military has said, “like sludge drying, the general investment per ton of wet sludge from 20 to 40 yuan, per ton of wet sludge incineration disposal of investment is generally 60 ~ 80 million. “such” astronomical figure “is even more staggering.

pay for sludge treatment - people in cash-strapped, the government “turning a blind eye”

Who is known as “money-burning” of sludge processing to pay for it? “Sludge treatment is a kind of environmental responsibility. Can be defined as a consumer pay for, that is, sludge handling charges levied; also be defined as a government fee, paid through taxes.” Fu Tao said.

the issue of fees for the sludge of Housing and Urban-Rural Construction Zhang Yue, deputy director of urban construction has said that “sewage treatment costs would include the cost of sludge treatment.” while a few cents a sewage treatment fee How can we include the huge sludge treatment cost? Fu Tao explained that in some areas of the sewage treatment fee is only included in sludge dewatering (which became 85% moisture content of sludge) and the removal and transportation costs, ie costs of sludge pretreatment. As for the “heavyweight” of the sludge drying and disposal costs are not included.

secondary pollution due to sewage sludge has not been raised high enough, many parts of the awareness of the problem of sludge treatment lags behind. “Failed to recognize the problem of urban sludge sewage treatment plants is largely because there is no normal operations. To some extent reflects the Government’s neglect of operational issues.” Fu Tao said, “and this neglect is not because of inadequate supervision, but often because of lack of money on. “

springing up of new technologies, such as sludge treatment more by” favored “

sludge treatment technologies are changing constantly pouring in the huge processing before the cost of finding the optimal balance.

Not long ago, Beijing Jinyu Group’s new North Water Cement Co., Ltd., Beijing, disposal of sewage sludge to start the project, the first systematic, large-scale problem of sludge disposal to initiate cracking of an uphill battle. Of its sewage sludge drying and ultimate disposal of new dry cement production technology is fully integrated, walk in the world.

while in Shenyang, Hunnan New Singapore Industrial Park, jointly developed with the Xi’an Jiaotong University, was designed to handle sludge and other organic waste continuous supercritical water oxidation and supercritical water gasification experimental device, created sludge treatment of “hot water treatment.” In supercritical water, organic matter and oxidants can quickly complete decomposition of organic chemical reactions, especially for sludge toxic, biodegradable organic matter has a unique effect. And “Boiled Law” dealing with the cost of sludge incineration method is only 1 / 3.

Taiyuan, Shanxi, a new energy-saving industry, Shun Wu Technology Co., Ltd. for sludge handling “recipe out”, the application rate of 80% of the sludge with water and lime, rice husk and coal mixed in proportion to the regeneration of forming sihe an organic fuel sludge generated by wastewater treatment plant can effectively be used. In situ treatment can effectively reduce transport costs and transport along the pollution, and the new sludge also odorless, heat the advantages of a more attract people’s attention.

sludge treatment for its high pollution, high cost of the “double high” features are increasingly more and more attention. As the inevitable product of sewage treatment, sludge continued to harm the environment should not be a “scapegoat.” Sewage treatment and sludge disposal at the same time must be two-handed grasp with both hands!

污水污泥处理-与两手抓两手都要！

今天，中国的污水处理厂之一正在兴建如同干涸的拉洋葱。废水为保证水质处理，促进中水回用的好方法，已被越来越多的人认可。对于供水企业，污水处理市场化道路也越来越大，宽，并作为“放长线钓大鱼污水处理厂，”在社会的经济风暴的市政基础设施项目的特点，一直充满了“的青睐。”对于

服务员和污水处理污泥，污水处理业将越来越高，在“喇叭声”，然后放大“哑哑。”政策研究中心，清华大学，水业董事，博士傅桃与有点无奈地说：“中国在该领域的污泥处理目前的发展是不够的。”

习惯称此为“轻重工业水泥浆的现象。”

政策，成本-都扼杀喉咙

污泥处理的有机化合物，是危险的致病人数众多污泥中的微生物，重金属，绝对不能忽视。周围的城市污泥变成污染，水土流失，空气，水和土壤次生来源，其对损害的危险程度远远大于水本身。

不能否认，污泥处理有自己难以突破的“瓶颈”：高能量，大型基础设施投资和其他问题上取得了污泥处理的成本继续上升;政府面临沉重的压力，污泥治疗的政策是不长的时间完成。

2008念7个月，污泥草案的环境管理制度和“环境管理体系的政策文件污泥最终政策文件研讨会”在表面上。坚持“城市污水处理厂污泥处理和处置最佳可行技术指南”，体现了主流技术方向，先进技术，“城市污水处理厂污泥处理处置技术政策”更容易获得和强制执行;“城市污染水处理厂污泥处理和处置“的技术规格，发挥市场的原则，污泥环境管理制度的政策文件正在进一步修改和完善的调节作用。

较高的污泥水分使水显着降低机械设备的内容已经变得非常困难，使用效果较好的热处理方法，面对巨大的能源消耗。此外，污泥处理工程巨大的投资。天津市市政工程研究院，赵越军队副总工程师说，像污泥干燥，每吨的湿污泥一般由20至40元的投资，占投资的湿污泥焚烧处置吨，“一般为60〜 8000万美元。“这样的”天文数字“，更是令人咋舌。

支付污泥处理-人的现金短缺的，政府“视而不见”

谁是“烧钱的污泥处理”之称的付出？ “污泥处理是一种保护环境的责任。可作为消费者支付，即污泥处理费征收规定，也被界定为政府费用，通过税收支付。”傅涛说。

的收费为住房和城市污泥，城乡建设张悦城市建设问题，副主任说：“污水处理费用将包括污泥处理的成本。”而污水处理费几毛钱，我们怎么能有巨大污泥处理成本是多少？傅涛解释说，在污水处理费的一些地区只在包括脱水污泥（成为85％的污泥含水率），以及排除和运输成本，污泥预处理，即成本。至于“重量级的干燥污泥和处理费用”不包括在内。

二次污染，由于污泥没有抬得够高的了污泥处理问题的认识，许多地方的滞后。 “没有认识到城市污水处理厂污泥的问题主要是因为没有正常运作。在一定程度上反映了政府运作问题的忽视。”傅涛说，“这不是因为疏忽监管不力的，但往往因为没有钱了。”

如雨后春笋般冒出更多的污泥处理新技术，以“天之骄子”

污泥处理技术不断地改变，在庞大的加工浇注前找到最佳平衡成本。

不久前，北京金隅集团新北水水泥有限责任公司，北京，污水污泥处置启动该项目，第一次系统，大型规模的污泥处置问题着手一场硬仗开裂。其污水污泥干燥和新型干法水泥生产技术的最终处置是完全集成的，在世界上散步。

而在沈阳，浑南新区新加坡工业园区，共同开发与西安交通大学，目的是要处理污泥等有机废弃物连续超临界水氧化和超临界水气化实验装置，建立污泥处理“热水处理。“在超临界水中，有机物和氧化剂可以快速完成，尤其是有毒污泥，可生物降解的有机物，有机分解化学反应，具有独特的作用。和“水煮法”与污泥的焚烧处理方法的成本仅为1 / 3。

太原，山西，新能源，节能产业，吴顺科技有限公司污泥处理有限公司“食谱”出去，在80与水和石灰，稻壳和煤泥％，申请率混合比例在寺河形成一个有机燃料的污泥污水处理厂所产生的再生可有效地使用。在现场处理能有效地降低运输成本和运输沿线的污染，新的污泥也无味，热更吸引人们的注意力的优势。

污泥的高污染“双高”的特点是成本高，处理越来越多的关注。随着污水处理的必然产物，污泥继续损害环境的不应该是一个“替罪羊”。污水处理和污泥的处理，同时必须两手，两手抓住！08.11.5
