China AF Integrated Water Purifier Equipment Sewage Treatment
■ Introduction
This series of water purification devices collect the essence of flocculation, sedimentation, sewage, backflushing, water collection and filtration and other processes. It is a series of water purification devices that can achieve fully automatic operation of monomers without human operation. It is an important unit to realize automatic management of water plants. , The water purification device has the advantages of wide application range, good treatment effect, excellent water quality, short construction period, small area, and investment saving.
Stripping technology has the characteristics of mature and high-efficiency, and the key points for the stripping control of ammonia nitrogen wastewater. According to the water quality pH data, it is usually adjusted by frequency conversion to make the wastewater pH 115 before entering the tower, and the blowing and dewatering temperature is usually controlled above 50°C. The pH adjustment tank is blown off by the first-stage blow-off tower by the lift pump, and the first-stage blow-off tower is blown off. The pH will drop after removal, so liquid caustic soda is added to further adjust the pH value. The wastewater pHNl15 of the secondary blow off. The ammonia nitrogen stripping tower adopts a two-stage countercurrent method. The ammonia nitrogen wastewater treatment process shows that under alkaline conditions T (pH=115), the ammonia nitrogen in the wastewater mainly exists in the form of NH3.
■ Application
The integrated water purifier is suitable for water purification in rivers, rivers, lakes, reservoirs and other water supply projects that use surface water as the water source, reclaimed water reuse, and coal mine tailings water, coal washing water, baths, swimming pools, car washes, papermaking , Printing and dyeing, electroplating and other industrial wastewater purification.
■ Working Principal
The purification process of the integrated water purification device is the same as that of the urban water supply plant. It has coagulation tank, sedimentation tank, filter tank, water quality stabilizing device, backwashing device, water pump and electrical control cabinet. Now they are introduced as follows
1. The raw water into which the coagulant is added to the coagulation tank is stirred by a mixer in the water inlet coagulation tank, so that the suspended solids in the water and the coagulant fully react to form rock flowers. A general water purification device uses a vortex reaction to mix the water and the coagulant, but the effect is unstable due to changes in the amount of water. The water purification device is mixed with a mixer, and the effect is not affected by changes in water volume.
2. The water in the sedimentation chamber is coagulated by adding coagulant to form rock flowers and flows into the sedimentation tank of the equipment for precipitation. The sedimentation tank adopts the inclined tube sedimentation method, and the solid-liquid separation is completed through the trapezoidal inclined plate sedimentation chamber. Mud bucket.
3. The sedimented water flows from the filter tank to the filter tank for filtration. The bottom of the filter structure is a water pipe, the middle part is quartz sand, and the upper part is anthracite. The filtration speed is 10m/h, and the clean water flows into the clean water tank for disinfection treatment before drinking. The recoil cycle of the filter tank is about 12 hours, and the recoil time is 5-10 minutes.

Combustion process and brief description:
The waste is manually put into the primary combustion chamber of the furnace body, and the automatic temperature control starts the primary combustion. According to the principle of combustion three T (temperature, time, vortex), it is fully oxidized, pyrolyzed and burned in the furnace body combustion chamber. The flue gas produced by incineration enters the second combustion chamber, and the unburned harmful substances in the flue gas are further destroyed in the second combustion chamber. In order to completely decompose the unburned embers and meet the emission requirements, the second combustion chamber is equipped with a burner to assist combustion, and is equipped with a unique secondary air supply device to ensure that the flue gas is in full contact with oxygen at high temperatures, and at the same time to ensure that the flue gas is in the second combustion chamber. The residence time of the combustion chamber is adjusted according to the oxygen content of the flue gas at the outlet of the second combustion chamber. The temperature in the second combustion chamber is controlled and the larger particles are removed by the dust collector, so that the incineration efficiency and destruction removal rate can reach more than 99%, so that it can achieve the effect of no odor, no odor and smoke, and reach the national emission standard. It enters the chimney and is discharged into the atmosphere, and the ashes produced after combustion are manually taken out, screened, transferred and buried.
