Meat processing wastewaterProcessing equipment——application area

The integrated sewage treatment equipment is mainly suitable for the treatment of domestic sewage in residential areas, rural towns, highway service areas, hotels, restaurants, hospitals, sanatoriums, schools, shopping malls, ship docks, stations, airports, industrial and mining enterprises, tourist attractions, villa areas, scenic areas, and other similar types of industrial organic sewage. Its main treatment method is to use the currently mature biochemical treatment technology-The biological contact oxidation method calculates the water quality design parameters based on the general domestic sewage water quality parameters,BOD5press200mg/lDesign.

Meat processing wastewaterProcessing equipment——automatic control

This equipment is buried and adoptsPLCCentralized automatic control. The lifting water pump is automatically controlled by a floating ball. When the water level in the regulating pool reaches a certain height, the entire equipment is automatically started. When the water level reaches a certain low level, the entire equipment automatically stops and is in standby mode.

When the water level exceeds the alarm level (i.e. when the water volume is particularly large), two lifting pumps can be automatically turned on to work simultaneously.

Two wind turbines are used alternately. When one is damaged, the other will automatically continue to operate continuously. When the equipment is in standby mode, the wind turbines will automatically operate intermittently to ensure the aerobic requirements of microorganisms in the contact oxidation tank.

Protection for faults such as phase loss, undervoltage, and overvoltage of each motor in the equipment, and audible and visual alarms.

Meat processing wastewaterProcessing equipment——Equipment installation, debugging, and maintenance:

Installation:

1User provided installation method: buried or above ground, and provide equipment foundation (concrete foundation) according to our company's equipment layout plan and equipment foundation diagram. The average bearing capacity of the foundation is required to be5000Kg/m2above.

The foundation must be level and the relative elevation must be accurate. During earthwork construction, the width must be distance from the foundation boundary line500 mmThe above facilitates the installation of equipment pipelines.

When using a crane to position the equipment, it is necessary to clarify the direction and position of each individual unit in order to correctly and conveniently connect the pipelines.

After connecting the pipeline, first conduct a pressure test with clean water to confirm that there is no water leakage in the pipeline connection. At the same time, adjust the levelness and outlet height of the sedimentation tank's effluent weir plate. Check the forward and reverse rotation of each motor equipment.

Check the overall equipment. After confirming the installation is correct, backfill the soil and prepare for debugging.

Debugging:

Debug the sewage pump to lift the rated flow of sewage to the equipment, and start the aeration system (the aeration rate can be increased appropriately during the initial debugging period). Check the growth of organisms in the contact oxidation tank through the inspection port every day. If conditions permit, users can use a microscope to observe the types and approximate quantities of organisms in the tank. When brown or yellow biofilms are attached to the packing, it can be considered that the biological cultivation has been successful and normal operation can be entered.

If the raw water is organic wastewater from a factory, domestic wastewater or artificial input of some biological nutrients can be used to cultivate biofilms first, and then industrial organic wastewater can be gradually added to domesticate and inoculate the organisms.

The average temperature is20At ℃, the cultivation time of biofilm in domestic sewage generally requires1－2Zhou, the cultivation and domestication time of industrial organic wastewater biofilm generally requires3－4Zhou.

maintain:

The grid well should be cleaned regularly, usually once a day, to prevent grid clogging.

During operation, conduct a patrol inspection every hour and promptly handle any abnormalities found.

During normal operation, the sewage flow rate should be maintained at20m3/hAt this time, the liquid level of the overflow vinegar tank in the primary sedimentation tank should be at the middle position of the sawtooth.

Under non abnormal circumstances, do not use the "manual" operation mode, and try to use the "automatic" operation mode as much as possible.

After the shutdown of the domestic sewage treatment system, the fans should be regularly put into operation to prevent biofilm death.

In order to improve the use of the equipment and ensure stable water quality, necessary maintenance and upkeep must be carried out on the equipment. Pumps, fans, etc. need to be regularly filled or replaced with oil. Generally, the fan is running10000－12000Maintenance is required every hour, and the submersible pump is running8000－10000Maintain once every hour.

The overhaul cycle of this equipment is generally10Year.
