Huangshi Zhengda's operation method using fiber ball filter pool

Fiber ball filter process: The coking wastewater is diluted with tap water to different concentrations to simulate actual water quality fluctuations. During the experiment, take a certain amount of coking wastewater, adjust the pH to 2~4 with sulfuric acid or hydrochloric acid, and inject the wastewater into the bottom of the micro-electrolysis column with a peristaltic pump at a certain flow rate.

Fiber ball filter process: The coking wastewater is diluted with tap water to different concentrations to simulate actual water quality fluctuations. During the experiment, take a certain amount of coking wastewater, adjust the pH to 2~4 with sulfuric acid or hydrochloric acid, use the peristaltic pump to inject the wastewater into the bottom inlet of the micro-electrolysis column with a certain flow rate, micro-electrolyze the water into the neutralization reaction tank, and add calcium hydroxide. (1O% lime milk) adjust the pH to 7.0-7.5, and simultaneously aerate and agitate (oxidize Fe2+ to Fe, precipitate in the sedimentation tank, precipitate the supernatant into the SBR biochemical pool, and precipitate the sludge into Set the mud pool.
Method of operation: The micro-electrolysis reaction operation is carried out for 6 h every day, and the micro-electrolysis column is backwashed with clean water every 1 d. The SBR operation cycle is 24 h (limited water intake for 6 h, aeration for 10 h, sedimentation for 1 h, drainage for 0.5 h, idle for 6.5 h).
Sample collection method: sample the microelectrolysis inlet, outlet, and sedimentation tank outlet once every 1 h, sample the water volume 200 ml, and mix the water samples together to obtain a mixture of each sampling port (6 times in total) 1200 m1), this can eliminate or avoid accidental errors caused by 1 sampling

1. Product introduction

   Coal-based columnar net gas Activated Carbon is cylindrical, tasteless non-toxic; as high quality Anthracite the raw material, by process of crushing, mixing, extrusion, molding, drying, carbonization, activation and made. It has reasonable pore structure, good adsorption properties, high mechanical strength, able to withstand the high temperature, high pressure and not easily broken, easy to regenerate, and low cost characteristics. It is widely used in sewage treatment, gas treatment, solvent recovery, desulfurization and denitrification, nitrogen making machine, air separation equipment, paint shop and other fields.


2. Application

a.Coal columnar net gas activated carbon used for purification, such as chemical raw materials, pharmaceutical chemical synthesis gas, industrial gas, nitrogen, chlorine, hydrogen chloride, ethylene hydrocarbons, ozone, ethane, butane, cracking gas, carbon dioxide and hydrogen used in beverage; atomic facilities exhaust inert gas and remove the pollutants; also separate and purify mixed gas. It also can be used for gas masks and protective equipment disinfection and filtration.

b.Coal columnar net gas activated carbon is mainly suitable for industrial waste treatment, such as waste gas power plant, chemical plant gas, coking plant, smelting plant, oil plant. Coal columnar net gas activated carbon rely on the good adsorption capacity, developed gap, high iodine value can make a cleaning purpose.

3. Adsorption purification principle and process

  The physical properties of coal-based activated carbon introduction: it is cylindrical black particles; the physical, chemical properties analysis of carbon is a porous carbon, the highly developed pore structure makes it has large surface area, so it is easy to full contact with toxic and harmful gases in the air (and harmful impurities), so this highly developed capillary and pore structure formed a powerful adsorption force field, which gives the unique adsorption properties of activated carbon.  

Adsorption: the organic waste gas passes through the filter removed the solid particulate material, from the upper to the lower into the adsorption tank. The organic matter is captured, absorbed and concentrated by the activated carbon, and the purified air is discharged from the lower part of the tank through the main fan into the atmosphere.

    Stop: when activated carbon adsorption reached saturation,it stops to inhalation waste gas; and then blowing up into the steam through the activated carbon bed, which expelled the organic matter from the activated carbon, and the subsequent restoration of desorption, activated carbon activity is recycled.

    Hot air drying and cooling: the activated carbon layer after desorption remains 80%-90% steam condensate which can in reducing carbon layer activity; therefore using the hot air to dry, close the steam valve, and then through the air cooling at 25 DEG C, activated carbon can be recovered into the circulation.
