Acid Recovery Purification and Regeneration System
What is the acid recovery purification and regeneration system?
Acid recovery purification and regeneration system mainly recovers nitric acid and hydrofluoric acid from mixed acid in stainless steel pickling process section. The metal and metal ions in waste acid are recovered in the form of metal oxide. The main purpose is to separate the metal fluoride and nitrate from waste acid from water by spray roasting. Metal salts combine with oxygen to form metal oxides, fluorine ions and nitrate combine with hydrogen ions to form hydrofluoric acid and nitric acid. Then return to the pickling section of the production line in the form of mixed acid of hydrofluoric acid and nitric acid for utilization.
Advantage for Acid Recovery Purification and Regeneration System
1. Greatly reduce the demand for new acid and the waste of resources. The recovery rate of nitric acid and hydrofluoric acid can respectively reach 80% and 99% .
2. No mixed acid neutralization and corresponding hazardous waste sludge caused. The mixed acid entering the system is converted into regenerated acid after passing through the acid regeneration system, and the waste gas generated is reduced to nitrogen and water through SCR to meet the discharge standard.
3. The metal oxide produced by mixed acid roasting can be recycled. The mixed acid is roasted to produce oxides containing chromium and nickel, which can be recycled to save social and public resources and realize the environmental protection concept of turning waste into treasure.
4. Most of the low nitrate water produced by ARP system is reused in the acid distribution tank, which basically realizes zero waste discharge of the system. The whole production process realizes automatic operation, and the automation level is in the first-class in China.
Biological Nitrogen Removal System
What is the Biological Nitrogen Removal System?
After physicochemical treatment, the nitrogen-containing wastewater with pH, heavy metals, suspended solids and other indicators which are up to the discharge standard is respectively transported to the adjustment tank for adjustment through pipelines. Then all will be lifted to the anaerobic tank through the adjustment tank lift pump. At the same time, methanol and phosphoric acid are added in proportion. After eight anaerobic denitrification reactions, the wastewater flows into the aerobic tank to produce nitrification reaction. Then the effluent from the aerobic tank overflows to the sedimentation tank. The supernatant from the sedimentation tank overflows to the discharge tank, and the precipitated nitrifying bacteria return to the anaerobic tank for internal circulation. With all these methods to remove TN from the wastewater..
Advantage for Biological Nitrogen Removal System
1. The TN removal rate is over 99%, the total nitrogen of effluent can reach the discharge standard, and the PH value of effluent is stable.
2. Automatic control is carried out by using precision instruments such as liquid level meter, flowmeter, online pH meter, ORP meter, do meter, sludge concentration meter, total nitrogen meter, COD meter and pneumatic valve components.
3. The system has high degree of automation, stable operation and low operation cost.
4. It is suitable for high nitrogen wastewater treatment.
Oily Waste Water Treatment
What is the Oily Waste Water Treatment?
With competitive price and timely delivery, HWHG sincerely hope to be your supplier and partner.
Most of the oil in oily wastewater coexists in several states, so multi-stage treatment method is needed to meet the discharge standard. Oily wastewater is recycled or discharged after treatment in oily wastewater regulation tank, PH regulation tank, demulsification tank, inclined plate sedimentation tank, dissolved air flotation tank, contact tank and buffer tank.
Advantages of Oily Wastewater Treatment System
1. The COD removal rate is more than 89%, the effluent COD is stable and meets the discharge standard. Also the effluent PH value is stable and meets the standard.
2. Automatic control is carried out with precision instruments such as liquid level meter, flowmeter, online pH meter and pneumatic valve assembly.
3. It is suitable for high concentration and low concentration oily wastewater.
Acid Cleaning Wastewater Treatment System
What is the Acid Cleaning Wastewater Treatment System?
It is a metal pickling wastewater treatment system includes a regulating tank, a neutralization tank, a coagulation tank, a high-efficiency clarification tank, a chelating reaction tank and a inclined plate sedimentation tank.
The mixed acid wastewater simply precipitates the granular sludge with large proportion in the sedimentation tank, and then it is lifted to the primary neutralization tank of the mixed acid wastewater through the lifting pump of the mixed acid wastewater regulating tank. Then flows into the secondary neutralization tank by gravity. By adding lime into the two-stage neutralization tank of the mixed acid wastewater, the metal ions and fluoride are further removed under the slightly alkaline condition.
The wastewater enters into the coagulation tank, adding PAC. At the same time, PAM is added before entering the clarifier, and sludge is precipitated in the wastewater reaction clarifier. The supernatant from the acid clarification tank successively enters the three-stage neutralization tank, chelation reaction tank and secondary coagulation tank for chemical reaction again. The effluent goes into the inclined plate sedimentation tank, and the effluent of the supernatant goes into the intermediate tank, and then goes through the pump lifting biochemical system for denitrification treatment.
Advantage for Acid Cleaning Wastewater Treatment System
1. The removal rate of heavy metals is more than 95%, the effluent heavy metals can reach the discharge standard, and the pH value of effluent is stable and controllable.
2. Automatic control is carried out with precision instruments such as liquid level meter, flowmeter, online pH meter and pneumatic valve assembly.
3. It is suitable for the treatment of mixed acid wastewater with low acid concentration.
4. The regulating tank is used to collect the wastewater discharged from the production line for centralized treatment.
Chromium-Containing Wastewater Treatment System
What is the Chromium-Containing Wastewater Treatment System?
Firstly, the chromium containing wastewater simply precipitates the granular sludge in the sedimentation tank. Then, in the reduction tank, a reducing agent and sulfuric acid waste liquid or sodium hydroxide are added to reduce the hexavalent chromium in the waste water to trivalent chromium ion. After reduction, alkali is added to make it generate chromium hydroxide precipitation under alkaline conditions, and then coagulant is added to remove chromium ion.
All the wastewater is filtered by the filter press and then sent to the reuse pool, which is then pumped to the reverse osmosis system for treatment. After RO membrane reverse osmosis treatment, the quality of fresh water effluent reaches the discharge standard and is discharged.
Advantages of chromium containing wastewater treatment system?
1. The removal rate of Cr (VI) is more than 99%. The heavy metal Cr and Ni in the effluent can reach the discharge standard. The pH value of the effluent is stable and up to the standard.
2. Automatic control is carried out with precision instruments such as liquid level meter, flow meter, online pH meter, ORP meter and pneumatic valve assembly.
3. It is suitable for the treatment of general wastewater containing chromium.
4. The regulating tank is used to collect the wastewater discharged from the production line for centralized treatment.
SCR Denitrification Equipment
What is the SCR denitrification equipment?
SCR denitration system is mainly composed of SCR catalytic reactor, reductant injection and flue gas bypass system. A method for selectively reducing nitrogen oxide to nitrogen by reducing agent under the action of catalyst. The main method is to inject reducing agent into the flue gas with the temperature of about 180 ~ 320 &#;, and reduce nitrogen oxide into nitrogen and water under the catalysis of catalyst in the equipment.
Advantage for SCR denitrification equipment?
1. Due to the use of catalyst, the reaction temperature is lower, the gas demand is saved and the energy consumption is reduced.
2. The purification rate is high, up to 90%.
3. The reduced nitrogen is vented without secondary pollution.
