Weiming’s subsidiary of Wenzhou Jiawei Environment Protection Technology Co., Ltd. and Shanghai Jiawei Environmental Protection Technology Co., Ltd. are the national high-tech enterprises dedicated to the investment, construction, operation, technical research and development and equipment manufacturing concerning the sewage, kitchen waste and sludge treatment projects.We have established strategic cooperation with multiple research institutes in China and we are actively engaged in the R&D of technological equipment.
Currently we have completed research on black and odorous water, anaerobic sludge digestion in sewage treatment plant, treatment of high-concentration organic wastewater and inorganic waste water treatment, river sludge solidification and resource utilization, and research of complete set of kitchen waste treatment facility.Through biochemical treatment, ultrafiltration, nanofiltration, and hyperfiltration, we are able to treat the landfill leachate whose COD concentration is 400 times higher than urban sewage to meet with reuse standard.
Kitchen waste is a major component of solid waste in the city of China.Due to the lifestyle and habits, Chinese residents produce massive number of kitchen waste, which has high water content and is easy to rotten and perish.It can significantly damage the environment if not dealt with effectively and timely. Considering the fact that kitchen waste is collected at fixed time in short period, Weiming Environment Protection adopts direct-transportation model of“bins waiting for the truck”, which significantly shortens the intermediary process and guarantees fast and effective kitchen waste pickup and removal. Weiming Environment Protection has adopted the treatment technology represented bythe primary“pretreatment+anaerobic digestion” model and secondary biomass purification and storage system, which takes“crude oil” and“biogas” as high value-added products.
At present, the company has invested and operated more than ten comprehensive kitchen waste treatment projects, including those in places such as Linjiang, Ruian, Pingyang, Yuhuan, Yongkang, Dongyang, Wuyi, Jiashan, and Jiangshan, etc.
Weiming Environment Protection has possessed the capacity to invest, construct, operate and run the sludge drying disposal project as well as the equipment development and manufacturing capacity.For the sludge filter-pressed in urban sludge treatment plant, the sludge with water content of 60~80% is dried to around 30%after centralized treatment before it is taken to the waste incinerator to be burnt together with the other domestic waste.Our sludge drying project is often constructed in combination with waste incineration plant, which allows the waste incineration plant to acquire heat source required for sludge drying.The dried high heating value sludge may be used in place of fuel, turning waste into valuable substance.
