Abstract
The utility model provides an alkali addition device for wastewater draining. The alkali addition device for wastewater draining is characterized in that a cylindrical iron container is arranged beside a water feeding tank, a water feeding pipe and a compressed air inlet pipe are connected to the cylindrical iron container and the water feeding tank, and the lower side of the water feeding tank is connected to a discharging pipe. The alkali addition device for wastewater draining can be used for ensuring that the pH value of water drained by water drainage factories reaches 6-9, and the purification efficiency of wastewater is improved.
Description
Technical field
The utility model relates to field of Environment Protection, is specifically related to the sewage drainage adder-subtractor.
Background technology
Known effluent from WWTP pH value requires between 6-9, need to add pharmaceutical chemicals adjusted as gone beyond the scope, the commonly used way that adds pharmaceutical chemicals is directly pharmaceutical chemicals to be thrown in water collecting basin, but water base of water collecting basin in static state, pharmaceutical chemicals can not dissolve rapidly, reduced purification efficiency, this drawback has been never had to good technical scheme and solve.
Summary of the invention
In order to solve effluent from WWTP pH value effect up to standard fast, sewage drainage adder-subtractor of the present utility model, can solve an above-mentioned difficult problem preferably.
In order to achieve the above object, sewage drainage adder-subtractor of the present utility model, establish cylinder sections container on pump sump side limit, water inlet pipe, compressed air inlet pipe connecting cylinder sections container and pump sump, the pump sump downside connects rising pipe, during operation, pharmaceutical chemicals is dropped in cylinder sections container by usage ratio as NaOH, open water inlet pipe and compressed air inlet pipe, air-flow is stirred in cylindrical container, make pharmaceutical chemicals fully in water, dissolve and flow into pump sump, make that sewage is fast up to standard discharges from rising pipe.
Adopt the beneficial effect of present technique to be: can make fast draining factory draining pH value reach 6-9, improve wastewater purification efficiency.
Below in conjunction with the drawings and specific embodiments, the utility model sewage drainage adder-subtractor is described in further detail.
The accompanying drawing explanation
1. cylinder sections containers in figure, 2. water inlet pipe, 3. compressed air inlet pipe, 4. pump sump, 5. rising pipe.
Fig. 1 is the schematic diagram of sewage drainage adder-subtractor of the present utility model.
Embodiment
The adder-subtractor of sewage drainage shown in Fig. 1, establish cylinder sections container 1 at pump sump 4 sides, and with water inlet pipe 2 and compressed air inlet pipe 3 connecting cylinder sections container 1 and pump sumps 4, pump sump 4 downsides set out water pipe 5.
Claims (1)
