In Dongguan alone, there are 34 sewage treatment plants that produce thousands of tons of sludge every day. Guangdong, which was struggling to find a way out for sludge, reported good news last week: After more than six months of trial operation, the first Huangjiang Sludge Treatment Plant with a total investment of 390 million yuan will be formally operational this month. According to Qi Jihong, Chief Engineer of Huangjiang Sludge Treatment Plant, “Sludge treatment plant was completed and put into trial operation in July last year. It has passed environmental protection acceptance.†There are 35 special transport vehicles in the sludge treatment plant. Each vehicle is transported one at a time. The amount is 15 tons. At the same time, in order to ensure safety, each vehicle is equipped with satellite positioning monitoring devices and emergency measures for sludge leakage. The control center of the sludge treatment plant can monitor the entire process of the sludge transport vehicle. According to reports, the sludge from the sewage treatment plant was treated once and the moisture content was reduced to 80%. The dehydration agent is added in the secondary treatment, the sludge is modified, reduced to a fluid state, and then mechanically dehydrated to reduce the moisture content of the sludge to 40%, and then the resource is reused. Even more amazing is that through the technical treatment, sludge has turned into a "treasure." Qi Jihong said that the sludge with a water content of 40% was crushed and dried to produce ultra-fine powder with moisture content of 1% or less as a plastic modified filler, and then the engineering plastics modification technology was adopted to transfer the sludge powder. The modification treatment is carried out to improve the compatibility and fluidity of the sludge powder and the plastic. The sludge powder and the plastic are made into a modified plastic pellet at a certain ratio. This modified plastic can produce a variety of plates, sheets, pipes, products can be applied to industry, construction, decoration industry and municipal engineering. In addition to being made into modified plastic pellets, the treated sludge can also be used in urban landscaping and the production of liquid fuel products. Sludge treatment in Zhongshan City uses anaerobic digestion/biogas production process. The city’s Chengtou Group stated that the gas project has invested a total of 190 million yuan. After the completion of the second phase of the project, 600 tons of sludge can be processed daily, and the daily production of methane is 10,000 to 20,000 cubic meters, which will achieve a good reduction, stabilization, harmlessness, and recycling of sludge. It is understood that the sludge disposal method in Guangdong was simple and the treatment rate for innocent treatment was very low. This situation has caused widespread public concern. In response, the Guangdong Province has requested that by the end of 2012, the harmless treatment and disposal rate of sludge in all parts of the province will reach more than 80%; by 2015, the province's sludge treatment rate will reach 100%. According to another understanding, according to the relevant plans of the Ministry of Environmental Protection, the next 10 years will be a golden period for China's sewage treatment and thousands of sewage treatment plants will be built. Some experts predict that during the “Twelfth Five-Year Plan†period, there is a huge potential for sludge treatment and disposal in China, and investment is expected to reach 60 billion yuan. 7Pcs Egg Cooker,Boiled Egg Maker,Automatic Egg Boiler,7 Egg Cooker Aiosa , https://www.nbaiosa.com
