Description

Power plant's intelligent electric flocculation treatment new device of waste water containing coal
Technical field
A kind of this utility model and power plant new device of wastewater treatment containing coal, especially a kind of electricity wadding having containing coal waste water Solidifying reaction, black water clarified separation and filtering technique and the intelligent place running and effectively removing the float in waste water of energy Reason device, specifically a kind of intelligent electric flocculation treatment new device of waste water containing coal.
Background technology
A certain amount of waste water containing coal can be produced at present, the main polluted factors in waste water are hanged during Coal Conveying System of Power Plant Float be up to 15000~20000 mg/litre, turbidity be more than 10000NTU, power plant's wastewater treatment containing coal generally arrange preliminary sedimentation tank with Second pond, preliminary sedimentation tank and second pond sedimentation coal slime are irregularly cleared up to coal yard using grab claw, and secondary clarifier effluent turbidity generally exists 700~5000 NTU, for make coal water handling reclamation in coal yard spray secondary clarifier effluent must carry out processing make the turbidity of waste water≤ 10 NTU, reach reuse water quality requirement, and the conventional process flow of domestic employing is as shown in Figure 1 at present.This set conventional processes Flow process has to plus coagulant and two kinds of medicaments of flocculation aid, and medicament needs dissolving and dosing pump dosing, and not only hand labor is strong Degree is big, and dosing pump easily blocks, and affects treatment effect, and therefore domestic only a few thermal power plant is at present using the electricity wadding being not required to dosing Solidifying handling process.The electric flocculation processing technological flow adopting at present is as shown in Figure 3.In this handling process, core technology is electricity wadding Solidifying, the reaction principle of electric flocculation is with metals such as aluminum, ferrum as anode, and in the presence of unidirectional current, anode is dissoluted, generation Al, Fe plasma, in a series of oxidizing process through hydrolysis, polymerization and ferrous iron, develops into various hydroxo complexes, multinuclear hydroxyl Complex so that hydroxide, makes colloidal state impurity in waste water containing coal, suspended impurity coagulative precipitation and separation. and meanwhile, powered Contaminant particle swimming in the electric field, its Partial charge is neutralized by electrode and promotes it to take off steady coagulation.Waste water carries out electrolytic flocculation During process, not only colloidal state impurity and suspended impurity there are is coagulative precipitation to act on, and the Oxidation due to anode and negative electrode Reduction, can remove multiple pollutant in eliminating water, such as COD, colourity etc..Due to poor using ferrum pole plate effluent color dilution, thus general All over from pure aluminum plate as anode and negative electrode, domestic at present be horizontal equipment for the electric flocculation casing containing coal wastewater treatment, The subject matter that design exists is as follows:
