Further preferably are as follows: rabbling mechanism is equipped in the pretreatment tank, the rabbling mechanism includes position motor, agitating shaft And several paddles, several paddles are fixed on agitating shaft, the output shaft of motor is fixedly connected with agitating shaft top.
Through the above technical solutions, setting agitating shaft and paddle are stirred in pretreatment pool, it can will be powdered Sodium hydrosulfite is stirred, and is made to react more thorough rapidly between sodium hydrosulfite and lye, is helped to improve the processing of pretreatment pool Efficiency.
Further preferably are as follows: the pretreatment tank is silent pond body and is equipped with exhaust pipe at top.
Through the above technical solutions, react after being contacted due to sodium hydrosulfite with water generate a large amount of heat and Liquor Hydrogen Peroxide, The toxic gases such as hydrogen sulfide then can be passed directly into atmosphere dirt by the way that gas collector is arranged in exhaust pipe one end to avoid gas Environment is contaminated, and exhaust fan can increase pressure increase to avoid gas in pretreatment pool, cause security risk.
Further preferably are as follows: exhaust fan is installed on the exhaust pipe.
Through the above technical solutions, installing exhaust fan on exhaust pipe, the gas circulation in pretreatment pool can be accelerated, made pre- Gas in processing pond is faster discharged, so that pressure in pretreatment pool be made to stablize, reaction safety is more preferable.
Further preferably are as follows: the exhaust pipe is connected to the bottom of the pH conditioning tank.
Through the above technical solutions, exhaust pipe is connected to the bottom of pH conditioning tank, then the titanium dioxide being discharged by exhaust pipe The gases such as hydrogen and hydrogen sulfide can be directly dissolved in the aqueous solvent in pH adjusting agent, water and acid be formed, to reduce acid pH tune The usage amount for saving agent both facilitates to reduce processing cost or more environmentally friendly.
Further preferably are as follows: the sludge outlet of the filter press is connected with filter residue case by pipeline and suction pump.
Through the above technical solutions, the filter residue that lye after filter press filters, leaves can be by pipeline and suction pump It send to being collected in filter residue case, then send into boiler room incorporation coal and burn up, filter residue is prevented to be deposited in open area after drenching with rain Form sewage pollution surface soil.
In conclusion the utility model has the following beneficial effects:
1. first reacting salkali waste with sodium hydrosulfite before carrying out acid-base neutralization to salkali waste, the coloration in salkali waste is removed And solid impurity, the impurity in salkali waste is reduced, salkali waste processing is more thorough than traditional direct neutralization mode;
It is passed directly into 2. salkali waste reacts the toxic gases such as the Liquor Hydrogen Peroxide generated and hydrogen sulfide with sodium hydrosulfite by exhaust pipe In pH conditioning tank, water and acid can be generated, to reduce the usage amount of acidic ph modifier, not only save the cost but also more environmentally-friendly.
