Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, this utility model is expanded on further.
As it is shown in figure 1, this utility model plant effluent enters collecting-tank through drainage pipeline gravity flow, drainage pipeline sets threeway
Pipe, one end is introduced accident emergency pond by Valve controlling.Sewage pump one installed by collecting-tank, and has liquid level controller according to liquid
The height of position automatically controls the keying of sewage pump.The water of collecting-tank is lifted into oil removal regulating reservoir 1 by sewage pump, and oil slick is fixed
Phase is by manually excluding.
Oil removal regulating reservoir 1 water outlet is lifted into first order reaction pond 2 by acid-proof pump, first automatic by pH value on-Line Monitor Device
Control the dosage of sodium hydroxide, and pH value is controlled in the range of 8.5～9, set compressed air in first order reaction pond 2 and inject
Mouth, alkali liquor inlet, former water inlet, PAM inlet, ferric chloride (FeCl36H2O) inlet etc., the flow of each inlet all has PLC
Integrating control.First order reaction pond 2 water outlet gravity flow enters first stage precipitation tank 3, makes zinc hydroxide, ferric hydroxide precipitate remove, precipitation
Thing enters sludge-tank 13.It is stand-by that first stage precipitation tank 3 water outlet enters intermediate pool 4.
Chemical reaction is mainly carried out in first order reaction pond 2, after adding sodium hydroxide suitable regulation pH value, Calx
In calcium ion and waste water in phosphate anion, zinc ion, iron ion etc. can produce chemical reaction, form zinc hydroxide and hydrogen
