new tactics continue to eat into the sludge output treasure -爱游戏官网

washington with the high consumption of jiangsu province along the yangtze river, the development of high-throughput industrial projects, the amount of sludge generated is also growing. taicang city, jiangsu province, in the process of disposal of sludge, and actively explore innovative sludge into the baby, "point mud into gold.
taicang first use of earthworms sludge ecological treatment, earthworms eat sludge, the sludge into ecological fertilizer. taicang city dragon agricultural farming limited earthworms harmless disposal of sludge production ecological organic fertilizer. in 2007, the company handled a total of 18,000 tons of sludge.
in april 2006, taicang dragon breeding earthworm introduction breeding experiments. after more than a year of operation, the company economies of scale is gradually expanding farming level is rising. on the basis of introduction of the japanese the ohira series seed, they turn industrial paper, sewage treatment sludge by earthworms eat into digestion becomes soft mud, reproduction processed into organic fertilizer to ensure that fertilizer nitrogen, phosphorus and potassium content reach the national standard.
electroplating sludge electroplating industry wastewater treatment "final state objects", the industry recognized intractable sludge. shun hui, the taiwan-funded enterprises of non-ferrous metal products company, has its own unique approach, using new technology and equipment are independently developed, these devices make electroplating sludge dehydration and drying after the rotary kiln, and separation of the heavy metal pollution mud, and then after melting metal ingots, and finally via the electrolysis will be able to extract useful metal objects. production scraps, the relatively high value of the heat of combustion of dry sludge add raw coal can be used as fuel, while the slag can be used to make bricks, and real electroplating sludge "eat dry pressing to do". the company introduced the second set of rotary kiln and refining furnaces, all put into one year can eat into 50,000 tons of sludge, produced 500 tons of precious metals.
