Shandong integrated living sewage treatment equipment water quality effect is not good, in fact, there are many reasons. General factors affecting the integrated domestic sewage treatment equipment are excessive water intake, equipment parameters debugging errors, microbial strain imbalance, too much residual sludge, the temperature is too low and so on. One of the more influential and frequent problems are as follows:
1, equipment water intake exceeds the standard
In most sewage treatment projects, sewage needs to go through the septic tank to remove large particles of impurities before entering the equipment. If the front-end pretreatment stage, the density of the grille is too large, it is likely to lead to some foreign matter into the equipment, which in turn causes integrated domestic wastewater treatment equipment clogging. In addition some of the catering type of domestic wastewater contains a large amount of oil and grease, if there is no grease trap facility, these oils and grease will float or attach to the sewage treatment equipment pipeline. Eventually lead to equipment purification rate is reduced, the water quality can not be stabilized to meet the standard.
2, equipment parameters debugging
Integrated domestic wastewater treatment equipment using biological treatment process, aeration equipment operating parameters need to be adjusted according to the specific circumstances of the project, if the parameters are not set reasonably, may make the dissolved oxygen in the water is insufficient, resulting in the residence time of the water flow can not meet the requirements, so the operating parameters of the equipment need to be set up by the professional commissioning engineers of the scientific specifications, in order to make the sewage is purified to meet the standards, and the water quality can not be stabilized. In order to make the domestic sewage is purified to meet the discharge standards.
3, residual sludge
Because the integrated domestic sewage treatment equipment is mainly used to purify pollutants by bacterial growth and reproduction, almost all the equipment in the operation of a few months or half a year after the equipment will precipitate a layer of residual sludge. If you do not clean up the sludge in time, the water quality of the equipment will be turbid, can not meet the discharge standards. Therefore, in the integrated domestic sewage treatment equipment operation and maintenance management, the need for regular cleaning sludge.
