Integrated wastewater treatment equipment biofilm method mainly includes biological contact oxidation, biofilter, biological rotor and other processes, different types of integrated wastewater treatment equipment in the production, design and manufacture of the process need to strictly comply with some industry regulations.
/
1, "Outdoor Drainage Design Code" (GB50014) is the biofilm method of integrated wastewater treatment equipment need to focus on the reference code. Conventional biological contact oxidation method should refer to the design of "biological contact oxidation method of sewage treatment engineering technical specifications" (HJ 2009).
2, integrated equipment filler more types of fillers, different categories of filler matters parameters are as follows: suspended filler fill rate control in 20% -50%, fixed-bed grid filler fill rate control in 60% -80%. Environmental Protection Products Technical Requirements Suspended Fillers (HJ/T 246), Environmental Protection Products Technical Requirements Suspended Fillers (HJ/T 245) and so on for the filler fill rate has a more comprehensive provisions.
3, in order to ensure that the membrane process wastewater treatment equipment water quality standards, usually the equipment will be set up inside the precipitation module, filtration module, membrane classification module, combined with the coagulation and dosing device can enhance the water quality of the equipment.
4, sedimentation tank design parameters and integrated wastewater treatment equipment purification effect is also somewhat related. Sedimentation tank process design parameters include surface hydraulic load, settling time and export weir load, etc., the design of the sedimentation tank should take into account the accumulation of sludge, sedimentation, slate and other adverse reactions. The design parameters of the sedimentation tank can be found in the "outdoor drainage design code" (GB50014) and other relevant standards and regulations.
