Wastewater oxygen can biodegradable experimental device,Electric flocculation reaction experimental device

1. Experimental purpose and principle:

Use contacting the oxidation tower (that is, the aerated biological sewage treatment device), and the water and --r intake at the bottom of the tower can make the water pollutants be mixed with the biofilms and --r in the fillers inside the tower, prompting the oxygen to move from the gas phase to the liquid phase From liquid phase to the biofilm, ensure that the microorganisms on the membrane have sufficient oxygen to decompose and metabolize the material.

Through this experiment, I hope to achieve the following goals:

1. Master the basic operation process of contacting oxidation experiments.

Wastewater oxygen can biodegradable experimental device,Electric flocculation reaction experimental device

1. Experimental purpose and principle of electric flocculation reaction experimental device:

This experiment is to insert multiple sets of electrodes of positive and negative in the wastewater. When it is passed by DC, the electrolytic, particle polarization, electrophoresis, oxidation reduction, between electrolytic products and the interaction between wastewater.

When using a soluble electrode (generally st--nless steel) as anode electrolyte, the anode metal will dissolve the cationic cation of aluminum or iron, and combine it with the hydroxyl (OH-) in the water to form aluminum, iron hydroxide with strong adsorption performance , To adsorb the impurities particles in the water, forming floccope. This kind of floccope and the micro -foam (hydrogen) produced on the cathode are separated by --r.

Second, technical indicators and parameters of the electrical flocculation reaction experimental device:
