With the development of cities and the increase of population, sewage treatment has become an important aspect of urban management and environmental protection. The area calculation of a wastewater treatment plant is determined based on its treatment capacity and process flow. This article will introduce the methods and precautions for calculating the area of sewage treatment plants.
1. Calculation method of sewage treatment plant area.
The area calculation of a wastewater treatment plant is determined based on its treatment capacity, process flow, and actual needs. Generally speaking, the area of a sewage treatment plant includes the following parts:
1.Pre-treatment area: including grids, grit tanks, regulating tanks and other facilities, which are used to remove large particles and suspended solids in sewage and prepare for subsequent treatment.
2.Biochemical treatment area: including aeration tanks, biological reaction tanks and other facilities, which are used to remove organic matter and nutrients such as nitrogen and phosphorus in sewage.
3.Advanced treatment area: including sedimentation tank, filtration tank, nitrogen and phosphorus removal facilities, etc., which are used to further remove pollutants in sewage to meet discharge standards.
4.Sludge treatment area: including sludge collection, thickening, dewatering and other facilities, used to treat sludge generated in the sewage treatment process.
5.Auxiliary facilities area: including substations, pumping stations, laboratories and other facilities to ensure the normal operation and management of sewage treatment plants.
According to the needs of the above districts, the area of the sewage treatment plant can be roughly calculated. In addition, it is also necessary to consider the area of factory roads, green belts, office buildings, etc.
2. Precautions for calculating the area of sewage treatment plant.
1.Process selection: Different processes have different treatment effects and processing capabilities, so their footprints are also different. When selecting the process flow, it should be evaluated and compared according to the actual situation, and the appropriate process flow should be selected.
2.Treatment capacity requirements: Treatment capacity requirements determine the size and footprint of a wastewater treatment plant. Capacity needs should be determined in accordance with the city's development plan and population growth trends**.
3.Land resources: Land resources are one of the important factors restricting the construction of sewage treatment plants. When selecting the site, the actual situation of land resources should be fully considered to ensure that the site selection is reasonable and legal.
4.Environmental impact: The construction and operation of the sewage treatment plant has a certain impact on the surrounding environment, and corresponding environmental protection measures should be taken to reduce the impact on the surrounding environment.
5.Economy: The construction and operation of sewage treatment plants require a large amount of capital investment, and its economy should be fully considered and an economical and reasonable plan should be selected.
III. Conclusion. Calculating the area of a wastewater treatment plant is a complex undertaking that requires several factors to consider. This paper introduces the methods and precautions for calculating the area of sewage treatment plants, hoping to provide some reference value for practical work. In practice, it should be evaluated and compared according to the specific situation, and the appropriate scheme should be selected to ensure the smooth construction and operation of the sewage treatment plant.
