The real-time monitoring value is sent to Cloud Server, remote monitoring center or hand-held by wireless network by the wireless transceiver
Intelligent terminal is communicated to connect by wireless network and Cloud Server.
9. according to claim 1 for preventing drop oxygenation device, it is characterised in that: the main pipeline and time pipeline
Inner wall is provided with helical duct.
10. a kind of -9 described in any item application methods for being used to prevent drop oxygenation device, feature according to claim 1 exist
In the application method includes the following steps:
1) parabola shaped deflector guidance upstream water flow pasting board flows down, and prevents water flow and plate from hitting and generates spray；
2) by drip pan, the main pipeline with preset diameters by the water flow of 17%-20% days inflows, full packages flows into downstream liquid
Face depth below guarantees that water inlet is flowed into without air under liquid level；
3) after the liquid level of drip pan is promoted to certain altitude, by the secondary pipeline with preset diameters by 60%-63% days into
The water flow of water water introduces downstream fluid level depth below；
4) water flow of remaining 17%-20% days inflow flows freely into downstream liquid by the overflow port at drip pan highest liquid level
Face；
In above-mentioned steps 1) in, upper water includes but is not limited to secondary clarifier effluent, returnedactivatedsludge mud mixture；Above-mentioned step
It is rapid 4) in, downstream fluid level water include but is not limited to denitrification bio-filter water inlet, activated sludge process main body biochemistry pool.
