Sewage Treatment Complete Set of Equipment Buried Integrated Sewage Treatment Equipment

Integration of sewage treatment equipment is a sunken pool, grade I, II will contact oxidation pond, pond, sludge concentration pool equipment, and in the I and class II contact oxidation pool for blast aeration, make contact oxidation method and the effective combination of activated sludge process has the advantages of both at the same time, and overcome the shortcomings of the two, to further improve the standards of sewage treatment.

Application:

The main treatment method is the contact oxidation method using the biochemical treatment technology. The design of integrated domestic sewage treatment equipment is mainly domestic sewage and similar industrial organic sewage treatment water quality parameters are calculated according to the general domestic sewage water quality, the inlet BOD5 is calculated according to 200mg/L.

Main components: 1. Hydrolytic acidizing tank; 2.2. Contact oxidation tank;3. Impurities settling tank;4. Disinfection treatment;Sludge aerobic digester.

1. Hydrolytic acidizing tank

Main treatment is the process of pretreatment before wastewater treatment, the wastewater in the water to certain anaerobic fermentation, the sewage, which can improve the biological sex, this is the sewage treatment of the more important step before, can directly affect the efficiency of wastewater treatment in the late and processing time, can improve the efficiency of wastewater treatment to a great extent and reduce consumption.

2. Contact oxidation tank

The oxidation pond is divided into several grades according to the pollution degree of water treatment, ordinary type and strengthened type.Generally, it is judged according to the processing time.The treatment time is no more than four hours for the use of the general type of oxidation pool, treatment time between four to six hours for the use of enhanced oxidation pool.The main method is to use hydrolytic acidizing pool to carry out biochemical treatment.Most of the organic matter in the original sewage is degraded and purified here. Aerobic bacteria use the organic matter in the sewage as feedstuff by using the organic matter in the sewage as carrier to decompose the organic matter in the sewage into inorganic salts, so as to achieve the purpose of purification.The existence of aerobic bacteria, must have enough oxygen, that is, there is enough dissolved oxygen in sewage, in order to achieve the purpose of biochemical treatment.Aerobic pool air is provided by the fan, the pool USES a new type of elastic three-dimensional packing, the packing surface area ratio is large, long service life, easy to hanging film, corrosion resistance, the bottom of the pool USES a rotary mixing aerator, so that the dissolved oxygen transfer rate is high, at the same time, light weight, not aging, not easy to plug, long service life and other advantages.The gas-water ratio is around 12:1.(0.5-5 m3/h contact pool is level 2)

3. Impurities settling tank

After the sewage is treated by the biological contact oxidation tank, the effluent flows into the sedimentation tank and further precipitates to remove the detached biofilm and some organic and inorganic particles. The sedimentation tank is based on the principle of gravity. When the sewage containing suspended solids flows from the bottom up, the matter is precipitated by gravity.Adjustable weir is set on the upper part of the sedimentation tank to adjust the water level.The lower part is provided with a conical sedimentation zone and a sludge gas plant. The air source is provided by a fan, and the sludge is transported to the sludge aerobic digester by air extraction.

4. Disinfection treatment

Disinfection tank according to specification «TJ14-74 & raquo;Standard is 30 minutes, if the hospital sewage, the disinfection tank to increase the residence time to 1-1.5 hours.Our company adopts chlorine dioxide disinfection device. The disinfection tank and disinfection device can continuously change the dosage according to the amount of water output, so as to achieve the purpose of more water and more medicine, less water and less medicine. If other devices are needed, they can be prepared separately.(if used in industrial sewage, disinfecting tank and disinfecting device may not.)

Sludge aerobic digester

In order to reduce the volume of sludge and improve the stability of sludge, the residual sludge discharged from the sedimentation tank is stabilized by aerobic digestion in the tank.After aerobic digestion, the amount of sludge is less. When cleaning up, a muck suction truck can be used to extend from the inspection hole of the sludge tank to the bottom of the sludge tank for suction and transportation (cleaning once every six months).A supernatant reflux device is installed on the upper part of the sludge aerobic digestion tank to overflow the supernatant to the hydrolytic acidizing tank.
