4.當原水濁度為100-500mg/L時,用量為5-10mg,即每千噸水5-10kg。使用前,據水質特點進行小試,選擇合適的值,然后施工使用。
一、在低濁度水中,將固體聚合氯化鋁產品按照1:3份額(分量比)加自來水稀釋,并且攪拌至完全溶解
二、在日子、出產用污水中,參照每噸污水先投加30g左右的聚合氯化鋁產品。然后投加稀釋之后的聚丙烯酰胺產品,(假如作用不明顯,請酌情減少或增加產品投加量。)
三、在造紙廠污水處理中,選用低濁度水的投進份額配備,如作用不明顯可在酌量增加。
四、原水濁度在100-500mg/L時,投加量為5-10mg即每千噸水投量為5-10kg,根據水質特性進行小試,選出合適值,然后投用。The proposal of this cause has attracted wide attention at home and abroad, and has been recognized as one of the most influential and recognized milestones in the field of environment in recent years.
Thereafter, the construction of the concept factory was vigorously promoted. By the end of 2014, the preliminary design and site selection work will be completed, the overall design will be completed in 2016, and the project construction approval and construction design will be completed in 2017. Officials said that the first sewage treatment conceptual plant could be completed in 2019.
Wang Hongchen, deputy dean of the Environmental College of Renmin University of China, told reporters that a year and a half ago, the sewage treatment conceptual plant had gathered a group of powerful basic teams to carry out relevant experiments on the spot, build production and R&D centers, speed up the transformation of science and technology, and carry out extensive industrial cooperation. "One is to build the experience center of new technology, promote the research and development, transformation and promotion of new technology; the other is to build the production-oriented research and development center of municipal sewage treatment, and build a new model of new technology from laboratory to practical application. Thirdly, we should promote the development of wastewater treatment technology from laboratory to engineering, and create a new high ground for China's cooperative industries.
According to the introduction, the concept factory initially established the technical route of sustainable water treatment facing the future, and established the business model and innovation model of "ecological complex" and "production-oriented R&D center" guiding industrial development.
For the basic ideas of the technical route, experts said that the main way is to improve energy recovery by carbon segregation, and to achieve the level of water treatment available. The effluent standard of "concept plant" will be much higher than that of current sewage treatment plants, which is of great significance for improving the quality of water environment and promoting ecological construction. "In the future, the conceptual plant will be expanded to an ecological area, like a demonstration of an urban ecological complex, and ultimately realize that a treatment plant can drive a city's ecosystem." Wang Hongchen said.
"Sewage treatment conceptual plant is an innovative work. It can not simply be regarded as a project, a project, a factory, but a social work to promote the leapfrog development of the industry." Wang Hongchen said so.
The damage of water pollution clearly shows that polyaluminium chloride is a reasonable way to deal with water pollution.
As a new year's first film, the piglet's past New Year is not the same as most movie promotion or promotion films. It's a story of "who is page". It's a story of "who is Paige": Li Yubao, who stays behind, doesn't know what his grandson wants to be "Paige". Finally, a pink Page was welded with a blower and sent to his grandson. Settlement Net Polyaluminium Chloride invites you to watch "What is Page"
What must be done and what must be said in the daytime can not be ignored now." Zhu Ziqing wrote in The Moonlight of Lotus Pond that "a person can think of anything and not think of anything in this vast moonlight, so he feels a quiet person." Last night, this valuable leisure was infected by a short video of "Who is Page?"
Henan Settlement Net Hebei Science and Technology Co., Ltd. year, has gone through 14 years in the beginning, the experience of the storm and pain in the hearts of the people, sweat and tears, success and happiness intertwined. Settlement net do not want to do anything is to do a good job of products, after hard struggle, our plant water treatment pharmaceutical products to reach the national GB15892-2003 specification. And through the ISO 9001:2000 international quality system certification, from all aspects of checks, the performance rate of the contract is 100%, the qualified rate of the products has reached 100%, which has been promulgated by the Municipal Technical Supervision Bureau as a reliable unit of quality and measurement.
According to the dosage of polyaluminium chloride in different water quality, the net settled polyaluminium chloride is introduced.
1. In low turbidity water, the solid polyaluminium chloride product is diluted by adding tap water in proportion of 1:3, and stirred until completely dissolved.
2. In daily and production wastewater, the polyaluminium chloride product should be added about 30g per ton of wastewater. Then add diluted polyacrylamide products. (If the effect is not obvious, please reduce or increase the product dosage as appropriate. )
3. In the sewage treatment of paper mills, the input share of low turbidity water should be selected and equipped. If the effect is not obvious, it can be increased at a reasonable level.
4. When the turbidity of raw water is 100-500 mg/L, the dosage is 5-10 mg, i.e. 5-10 kg per thousand tons of water. It is better to carry out small-scale tests according to the characteristics of water quality before using, select the appropriate value, and then put it into use.
