1. Cost composition of sewage treatment plant 1. Direct costs a. Energy costs: including electricity and water, of which electricity is the main cost, accounting for about 40-50% of the total cost. b. Material costs: including flocculant fees, laboratory fees, low-value consumables, etc. c. Direct labor and welfare expenses: wages and welfare expenses of all production personnel. 2. Manufacturing expenses include maintenance fees, raw material fees, spare parts fees, etc. 3. Various expenses incurred by the period expense management department to organize and manage production, including administrative management, various department management expenses, financial expenses, equipment depreciation expenses and Other indirect costs. 4. Analysis of sewage treatment cost components 1. Among production costs, electricity consumption and chemical consumption are expenses that must be incurred during the production process, and they account for a large proportion. They must be strictly controlled during the production process to effectively reduce costs.
2. Staff wages and benefits in production costs are the driving force to improve employee enthusiasm, enhance corporate vitality and cohesion, and further save energy and reduce consumption. They are also a symbol of the development level of the company and society. Under normal production and operation conditions, the higher its proportion, the better the development of the enterprise. 3. On the basis of sustainable development of the enterprise, manufacturing costs should be minimized in maintenance, overhaul and fixed asset investment to maximize corporate profits. 4. Management fees are an integral part of enterprise operating costs and should be controlled to minimize unnecessary expenditures and reduce costs. 5. Sewage treatment plant cost calculation 1. Electricity cost: The equipment that consumes the most energy in sewage treatment companies includes various types of water pumps, oxygen supply equipment such as blowers, and sludge concentration and dehydration equipment. To calculate the unit consumption of sewage treatment, on the one hand, you can Based on the analysis based on the number and power of equipment used, on the other hand, combined with the statistical analysis of the enterprise's sewage treatment unit consumption in previous years, and referring to relevant local standards, a reasonable sewage treatment unit consumption suitable for the enterprise was formulated. For example, the operation and management assessment standards for urban sewage treatment plants in Jiangsu Province have clear assessment requirements for unit consumption of sewage treatment. The unit consumption assessment of Class A sewage treatment is divided into four levels, ≤0.34 degrees/cubic meter, 0.34 degrees/cubic meter. -0.37 degrees/cubic meter, 0.37 degrees/cubic meter-0.42
