The reason for the turbidity of the water from the Hubei project rural sewage treatment equipment, in fact, there are roughly four factors. Now the rural sewage treatment equipment has been widely used in the village and town environmental management, beautiful new rural construction and other sewage treatment projects, water turbidity should be timely attention, attention.
1, the sludge is not timely cleaned up: most of the rural sewage treatment equipment used in the biological treatment process, the use of microorganisms in the activated sludge to purify the sludge. Sludge is generally 6-12 months need to clean up once, if the sludge is not timely, the turbidity of the water from the equipment will be significantly increased.
2, poor filtration of the grille: domestic sewage before entering the equipment generally need to be filtered through two layers of coarse and fine grille, some of the rural sewage treatment station of the grille aperture is too large, does not play a good filtering effect. Resulting in a large number of debris into the rural sewage treatment equipment, ultimately causing the equipment to blow water turbidity.
3, the sewage contains more grease: domestic sewage once the content of oil and grease components are elevated, it will affect the purification efficiency of rural sewage treatment equipment, rural areas engaged in food and beverage, farmhouse and other business sewage need to use grease trap, otherwise the grease not only affects the efficiency of purification, but also lead to clogging of the pipeline.
4, improper commissioning of equipment parameters: rural sewage treatment equipment in the aerobic and anaerobic reaction is a critical step, aerobic sludge load is too small, aeration is too much, the sludge itself oxidation, resulting in poor flocculation of sludge, sludge structure dispersion (turbid water and suspended solids) aerobic sludge sludge sludge expansion phenomenon, poor sedimentation, sedimentation tank mud layer is high, the flow of water will be brought out of the sludge (SVI value is too high or too low will occur). (SVI value is too high or too low will appear this situation).
