1, interceptor equipment
Interceptor equipment is mainly a grille. Grid type selection depends on the specific requirements of the sewage treatment plant and the placement of the location. Specific requirements are grating spacing, grating cross-section shape (round cross-section grating hydraulic conditions, water resistance is small, but poor stiffness, generally use rectangular cross-section grating), installation angle (grating the upper part of the well can be used to reduce the height of the grating of the concrete breast wall or steel plate full seal), the flow rate, grating slag, slag clearing (fine grating using a spiral conveyor. (When the sewage has larger impurities with a belt conveyor).
2, sand sedimentation equipment
Sand sedimentation equipment has aeration sand filter, sand filter, circular eddy current sand filter. Aerated sand sedimentation tank is more familiar, Dole sand sedimentation tank of the bottom of the pool with a sand scraper mounted on the rotating shaft, the sand from the center to the edge of the sand scraping, into the sand collection hopper. Specific sand sedimentation tanks include an axial screw mixer. Sand pump, vacuum starting device, thickener, sand and water separation conveyor, in situ control machine and so on. Sand discharge equipment is divided into gravity sand discharge and mechanical sand discharge. Specific sand discharging machine has traveling pump suction sand discharging machine, chain bucket sand scraper, chain plate sand scraper. Sand water separator has spiral sand water separator, cyclone sand remover. Spiral sand conveyor. Sand sedimentation equipment has ordinary sedimentation tank, spoke flow sedimentation tank, vertical flow sedimentation tank.
3, air flotation equipment
Air flotation equipment is divided into the general direction of dispersed air flotation equipment, dissolved air flotation equipment, floating liquid, slagging in addition to equipment. Dispersed air flotation equipment according to the crushing method is divided into pump suction pipe suction air flotation, jet air flotation, diffusion aeration air flotation and impeller air flotation.
4, scraping machine
Scraper is divided into traveling scraper, rope towed scraper and chain towed scraper. Chain scraper generally use planetary cycloid reducer. When conditions permit can choose other. Try to choose to change the size of the sprocket radius.
5, mechanical aeration device
Mechanical aeration device has a pump-type impeller aeration device, K-type impeller aeration device, inverted umbrella impeller aeration device, flat impeller aeration device. The current application of horizontal axis type aeration device is mainly horizontal push-flow aeration device.
6, decanter
Decanter rainbow decanter, flexible pipe decanter, sleeve decanter, rotary decanter. Biofilm method mainly has biofluidized bed. There are mainly liquid and gas fluidized bed.
7, anaerobic wastewater treatment equipment
Anaerobic wastewater treatment equipment has ascending anaerobic sludge bed. Anaerobic anoxic treatment typical auxiliary equipment has diving mixing device. Commonly used QJB series submersible mixer, SM type submersible mixer.
8, mud equipment
Discharge of mud equipment are advection type, spoke flow type, inclined tube, accelerated clarifier. Specific mud scraper has traveling suction mud scraper, double wire rope traction mud scraper.
9, sludge gravity thickening equipment
Sludge gravity thickening equipment is divided into a break and continuous gravity thickening pool, sludge flotation thickening equipment and sludge centrifugal thickening equipment.
10, sludge anaerobic digestion equipment
Sludge anaerobic digestion equipment, mixing equipment, digestion heating equipment, biogas utilization equipment.
11, sludge dewatering and drying equipment
Sludge dewatering and drying equipment has vacuum filtration equipment, filtering and dewatering equipment, rotary butterfly sludge dewatering machine.
