Assessment of sewage sludge management at Thu Dau Mot wastewater treatment enterprise

Abstract

Binh Duong province has built and put into operation 29 industrial zones and 10 industrial clusters, contributing to the strong socio-economic development and accompanied by environmental concerns, especially management, waste treatment in general and waste from drainage systems and sanitation works in particular. Thu Dau Mot wastewater treatment enterprise was built including works such as: inlet works, ASBR tank, and disinfection house, sludge concentration tank, sludge extractor, house deodorizing, and so on. The quality of water after treatment meets QCVN 14: 2008 / BTNMT standards (column A), contributing to the protection of Saigon river water sources, ensuring the aesthetics and environmental sanitation of Thu Dau Mot city area. The factory was installed ASBR circulating activated sludge treatment technology, limiting odor generation, not affecting the surrounding environment, increasing 30% of design capacity compared to traditional SBR tanks of the same volume, easy to operate, low operating costs and saving power. The most common non-toxic organic compounds include materials of plant and animal origin such as proteins, amino acids, sugars, fats; compounds containing N, P. Toxic organic compounds include compounds of alkyl phenols, chloro-benzenes. Metals such as: Zn, Pb, Cu, Cd, Ni, Cr, Hg, As. Some of these compounds can be toxic to humans and animals. Harmful microorganisms such as pathogenic bacteria, viruses together with parasitic helminthes can increase the potential harm to human, animal and plant health. Inorganic compounds such as silicates, aluminates, and magnesium compounds. After being treated, the sludge will be collected and transported to South Binh Duong Waste Treatment Enterprise to produce construction materials and make compost.
