Pump Selection in Municipal Wastewater Treatment
In municipal sewage treatment, the selection of pumps is a crucial link, which directly affects the efficiency, cost and stability of the entire system. The following are some key points about the selection of pumps in municipal sewage treatment:
1. Selection of pump types
Submersible sewage pump (WQ type)
Features: Submersible sewage pumps can be fully submerged in sewage and are usually installed in sewage wells. It has the advantages of small size, low noise, easy installation and simple maintenance. Since it is isolated from the air during work, it will not generate noise and odor, making the environment of the sewage pumping station cleaner and more comfortable.
Scope of application: Suitable for working conditions that need to be flooded and places where there is no land installation space. There are various types of submersible sewage pumps, such as cutting type, stirring type, stirring cutting type, etc., which can be selected according to specific needs.
Centrifugal sewage pump
Features: Centrifugal sewage pumps have stable performance, large flow, high working efficiency and wide application range. It can choose different impellers and bearings according to different working conditions to achieve good pump efficiency and durability. It will not produce much vibration during work, which can avoid the impact on the pump room structure.
Scope of application: Applicable to various municipal sewage pumping stations, especially those requiring large flow and high efficiency.
Diesel double-suction pump
Features: The diesel double-suction pump is driven by a diesel engine and is suitable for working in an environment without power supply. It has the advantages of strong portability, flexible transmission, and high operating reliability.
Scope of application: In response to natural disasters and emergencies, the diesel double-suction pump can play its emergency treatment role. However, in municipal sewage pumping stations with long-term stable operation, it can be used as a backup pump or emergency treatment pump.
Other types of sewage pumps
Such as non-clogging pipeline sewage pumps (GW type), non-clogging submerged sewage pumps (YW type), vertical non-clogging sewage pumps (WL type), self-priming non-clogging sewage pumps (ZW type), etc. These pumps have their own characteristics and can be selected according to specific working conditions and needs.
2. Selection suggestions
Comprehensive consideration: When choosing a sewage pump, it is necessary to comprehensively consider factors such as the type, parameters, cost, energy consumption, and ease of maintenance of the pump to select the most suitable pump type.
Professional consultation: It is recommended to consult a professional pump manufacturer or sewage treatment engineer to obtain more professional selection and configuration suggestions.
Actual test: If conditions permit, the selected pump can be actually tested to verify its performance and effect.
Backup pump setting: In order to ensure the continuity and stability of sewage treatment, it is recommended to set up a backup pump to deal with emergencies. The number and type of backup pumps need to be determined according to actual needs.
