An experimental device of livestock and poultry wastewater treatment

Livestock and poultry wastewater treatment equipment is a "environmental engineering" specially opened for large and middle schools. "Environmental monitoring and governance technology". "Environmental monitoring and evaluation", "water environmental monitoring and protection", "urban water purification technology", and "technology" and other environmental related majors developed comprehensive tr--ning platforms developed by environmental categories. This tr--ning platform can not only reflect the classics of typical sewage treatment technology, but also reflect the advanced sewage treatment combination process system). It promotes the reform and innovation of talent tr--ning models through tr--ning platform tr--ning to cultivate students' sust--nable sust--nable av--lability of students Development capabilities provide professional talents in the installation, commissioning, and water quality detection and analysis of water treatment equipment that meets the needs of corporate needs.

1. Environmental temperature: 5 ℃ ～ 40 ℃

2. Treatment of water: 50 ～ 100L/h,

3. Total size of the device: 2200mm × 800mm × 1600mm.,

4. Work power: AC220V ± 10%, 50Hz, single -phase three -line system, 2300W power, safety protection: ground protection, leakage protection, overcurrent protection

3. System composition and function

Comprehensive tr--ning equipment for livestock and poultry wastewater treatment is m--nly composed of three parts: control system, water supply system and sewage treatment system.

Control system: m--nly by electrical control cabinets, touch screens, knob switches,

Touch screen control can also be manually, online monitor (pH and DO instrument), monitoring, etc., and the water supply system: m--nly consisting of water tanks, st--nless steel brackets, water tank liquid level pipes and ball troubles. Sewage treatment system: The overall device object and equipment are designed with a st--nless steel frame. The m--n power system device is installed on the steel frame. The m--n organic glass reactor is reasonably decorated with the upper layer of the st--nless steel steel frame. The lower power system is m--nly composed of water pumps, fan, and middle pool devices. The organic glass reactor system is m--nly composed of organic glass flat -type sedimentation tanks, CSTR pools, spoke -type sedimentation tanks, UASB pools, SBR pools, flocculation sedimentation tanks, disinfection ponds, solid fluid separators, organic glass neutral ponds. The aeration system is m--nly composed of a fan, aeration pipe, a mixer, a flow meter, and a pipeline. The online monitoring system is m--nly composed of DO online meter, pH online meter, and floating ball liquid level switch.

Hydraulic technology has been widely used in various fields in my country. Because the hydraulic system is a comprehensive structure of machinery, electricity, and hydraulic systems with complex structures and high precision. The diagnosis of hydraulic faults is difficult, and it often becomes a major obstacle for enterprises to produce smoothly. This experimental desk will teach correct ideas, scientific methods and advanced experience through typical f--lure diagnosis, so that students can master the hydraulic system f--lure analysis skills and quickly and accurately find the fault.
