Description
Technical field
The utility model belongs to industrial effluent reusing technical field, particularly a kind of for heat-engine plant desulfurized Wastewater research device.
Background technology
The wet desulphurization that thermal power plant extensively adopts can produce desulfurization wastewater in process of production.Compared with the waste water produced with thermal power plant other system, the water quality of desulfurization wastewater is very special, and the suspended substance containing high density, inorganic salt and each heavy metal species, have very strong contaminative to environment, intractability is larger.Therefore, individual curing must be carried out to desulfurization wastewater.
Desulfurization wastewater has the feature of water quality and water yield instability.The compound part that the elements such as F, Cl, Cd, Hg, Pb, Ni, As, Se, Cr in fire coal generate in burning is discharged with slag, flying dust, and another part enters desulfurizer absorbing tower with flue gas, is dissolved in and absorbs in slurries.In addition, the impurity contained in lime also incorporates in slurries to some extent.Therefore, desulfurization waste water quality often has very big-difference, even if same set of desulfurizer, the waste water quality of discharging in different steps is also not quite similar.The total feature of desulfurization wastewater is: suspended substance and COD higher, easily precipitate; Containing enough saturated sulphite, vitriol and heavy metal.According to discharging standards, the main transnormal items of desulfurization wastewater comprises suspended substance, heavy metal ion, COD etc.Most impurity can be removed by chemical precipitation.In actual motion, the factor affecting chemical precipitation mainly contains pH value, water temperature, the consumption of coagulating agent, having used of coagulant aids.The actual water temperature of desulfurization wastewater is general higher, and enter the water temperature of Waste Water Treatment at 30 ~ 40 DEG C, this is favourable to the precipitin reaction of most metal ions.For the characteristic of above-mentioned desulfurization wastewater, develop the method for treating desulfurized wastewater under various condition, improve various desulfurization wastewater processing efficiency targetedly and just seem very necessary.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of for heat-engine plant desulfurized Wastewater research device.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of for heat-engine plant desulfurized Wastewater research device, comprise cleaned water tank, the left bottom of cleaned water tank is sewage water inlet pipe, at the top of cleaned water tank, agitator motor is installed, PH value detector and unslaked lime medicine system, the motor shaft of agitator motor penetrates casing downwards and extends in the middle part of casing, stirring rake is installed in motor shaft lower end, sewage is sent into settling tank by the pipeline of right side wall by cleaned water tank, coagulating agent medicine system and flocculation agent medicine system are installed above settling tank, BF biological filler swimming-bed reactor is sent into through pipeline by the sewage after settling tank process, water after purification is discharged by pipeline.
And, the water tank wash water valve of pipeline communication is housed respectively in the bottom of described cleaned water tank and settling tank and precipitates wash water valve.
And the bottom of described BF biological filler swimming-bed reactor is provided with equally distributed venting hole, and air is entered in the waste water of BF biological filler swimming-bed reactor by venting hole by air pump.
Advantage of the present utility model and positively effect are:
The utility model devises sewage experimental study device for the feature of power plant desulfurization waste water, concrete unslaked lime chemical feeding quantity, coagulating agent chemical feeding quantity and flocculation agent chemical feeding quantity are found out to the desulfurization wastewater of different situation, find out best effect, synchronous aeration is carried out to BF biological filler swimming-bed reactor simultaneously, determine best effect, the utility model is that extensive desulfurization wastewater process provides the foundation experimental data.
