Municipal sewage sludge contains a variety of harmful substances, and untreated sludge will cause environmental pollution.
Beijing Aoli Aide Technology Development Co., Ltd. added “acid-base two-component self-heating agent†to dry, dehydrate, sterilize, and modify sewage sludge, and obtained calcium oxide content in the sludge treatment. About 50%-55% of the chemical composition of the dryer and limestone for cement production is very close, and it is possible to use it as a raw material for cement production. The use of sewage treatment plant sludge treatment of raw materials for cement raw materials, can have good burnability index, a large amount of calcium hydroxide in the sludge, which has a higher reactivity than calcium carbonate in cement raw materials.
The unique ORT sludge drying system developed by Beijing Aoli Aide Technology Development Co., Ltd. is composed of a sludge screw conveyor and a solidifying material conveyor. The agitation, mixing, heating, sterilization, drying equipment and drying granulation are integrated processes. The reactor and the washing dust collection and deodorization slow rotation within 5-10 minutes, the equipment failure rate is low, no flame chemical reaction, direct heating. Reduce energy consumption, equipment investment is low, and reuse is widely used. The calcium, iron and aluminum elements added during the detoxification and reduction process are accepted by many building materials products. The harmful elements originally contained in the sludge, such as copper, zinc, lead, chromium, and mercury, are fixed in a "blunt" state, which reduces the water leaching property. Sludge is treated from the source to complete the benign cycle of harmless, reduced and recycling of urban waste. The dryer provides a new technology and new technology for China's environmental protection industry to catch up with similar products in advanced countries. Way out.
After review by experts, the Sludge Calcium-enhanced Desiccation System equipment of Beijing Aoli Aide Technology Development Co., Ltd. has been approved by the Beijing Municipal Science and Technology Commission, the Beijing Municipal Development and Reform Commission, the Beijing Municipal Construction Commission, the Beijing Bureau of Industry and Commerce, and the Zhongguancun Management Committee. It was identified as the second batch of independent innovation products in Beijing. It is included in the catalogue of independent innovation products of government procurement, giving priority to the support of government procurement.
Beijing's independent innovation product selection and certification activities are the supporting policies of the Beijing Municipal Government to implement the State Council's "implementation of the National Medium and Long-Term Scientific and Technological Development Plan Outline (2006-2020)" and the Beijing municipal government's "Increasing Autonomy" "Innovative capacity to build innovative cities", to promote the role of public finances in promoting independent innovation, to enhance the independent innovation ability of enterprises as the main body, and to promote the high-tech industry's high-speed development and conduct the selection and recognition activities. The identified products cover technologies, products or services that meet the priority development areas of Beijing, such as information technology, bio-medicine, new materials, optical-mechanical integration, energy conservation and environmental protection, and cultural creativity. They all possess high innovation and technology. Advanced nature. It is reported that any products that have been identified will be included in the list of independent innovation products of Beijing Municipality and will be recommended in the procurement of fiscal funds such as government procurement and national major project procurement, and in the identification of high-tech enterprises and the promotion of the transformation of scientific and technological achievements and related industries. Support for key policies.
