Problems solved by technology

[0005] There are deficiencies in the design of the above-mentioned fan room power supply system: First, the lightning protection measures are not good enough. When the lightning current is too strong, a small part of the lightning current may enter the load equipment, which will cause the load equipment to be damaged under the impact of the lightning current residual voltage. , which makes the system less secure and greatly shortens its service life; second, the anti-interference measures are not ideal, and the load equipment is easily disturbed by factors such as power supply and external environment, which has a great impact on the stable operation of the load equipment; The reason is that the control is not convenient enough, and the adjustment of its control parameters is not flexible enough to meet the needs of users well.

Abstract

The invention discloses a buried sewage treatment equipment fan room. A power distribution cabinet and a fan system connected with an air supply pipeline are arranged in a machine room body, the fan system is provided with more than two fans for aeration, and the fans serve as load devices connected to a power supply device though drive modules. The power supply device is connected with the drive modules through connecting cables, the drive modules and the load devices are connected through connecting cables, at least one core wire is arranged in an outer protection layer of each connecting cable and wraps an inner protection layer. Input stages of the drive modules are connected with a filtering decoupling circuit for inhibiting differential mode interference from the power supply device, a first lightning protection circuit including an airtight spark gap or a grounding resistor is connected between the input ends and the grounded ends of the drive modules, and a second lightning protection circuit including a discharging tube or a grounding resistor is connected between the output ends and the grounded ends of the drive modules. The buried sewage treatment equipment fan room can improve the performance of a power supply system on at least one aspect of safety, anti-interference or controllability and the like.

Description

technical field [0001] The invention relates to a sewage treatment technology, in particular to a power supply system and ancillary facilities of a fan room of an underground sewage treatment equipment. Background technique [0002] The buried sewage treatment equipment is a kind of sewage biological treatment system with biofilm as the main body of purification. It has the characteristics of low consumption, stable operation and convenient maintenance, so it has a wide application prospect and promotion value. [0003] Typical buried sewage treatment equipment includes grid wells, regulating tanks, primary sedimentation tanks, dynamic oxidation contact tanks, clarifiers and fan rooms connected to the dynamic oxidation contact tanks; the dynamic oxidation contact tanks include reactors The main body, the inner shell of the reactor, and the rotary-cut agitator; the inner shell of the reactor is arranged inside the main body of the reactor, and its bottom opening communicates...
