The cost of a 300-ton-per-day wastewater treatment project is a complex issue related to factors such as project size, technological flow, and pollutant content. Before starting the project, it is necessary to conduct preliminary research and process selection. According to the characteristics of the wastewater, the appropriate treatment process is selected. Common treatment processes include physical, chemical, and biological treatment. Each process has its own characteristics and scope of application, so it must be selected according to the specific situation of the wastewater, combined with the engineering requirements and the expected results.
On the basis of engineering selection, the equipment is purchased. Wastewater treatment equipment involves sedimentation tanks, air flotation tanks, biochemical tanks, filters, sterilizers and other equipment. The purchase of these equipment needs to comprehensively consider the performance, durability, technical indicators and so on. At the same time, it is also necessary to consider the operation and maintenance costs of the equipment as well as the required human resources. In order to ensure the normal operation and service life of the equipment, it is also necessary to purchase relevant auxiliary equipment and spare parts.
In addition, wastewater treatment projects also require civil works, such as the construction of septic tanks, regulating tanks, and pharmacies. Civil construction involves site preparation, procurement of building materials, construction labor costs, etc. During the construction process, the equipment also needs to be installed and debugged to ensure its normal operation.
