Generally, the rising flow rate of the inclined tube sedimentation zone can reach 20-30 m/h (5.6-8.3 mm/s).
The utility model has very flexible operation and can cope with the situation of great change of the processing flow. For the treated water quality, abrupt changes of raw water quality (such as generation of turbidity peaks) can be dealt with by adjusting the reflux rate of the sludge, and the reflux rate of the sludge can be adjusted by adjusting the number of reflux pumps operated.
When the device works, the coagulant can be firstly added into sewage, and is quickly mixed with suspended matters in the sewage under the action of the quick stirrer, and the particles are destabilized by neutralizing negative charges on the surfaces of the particles to form small flocs which then enter a flocculation tank. And meanwhile, phosphorus in raw water reacts with a coagulant to form phosphate so as to achieve the purpose of chemical phosphorus removal. The returned sludge and the small floccules formed by coagulation are quickly mixed under the action of a quick stirrer, and the sludge is used as a core to form larger and heavier floccules so as to be beneficial to quick sedimentation in a sedimentation tank.
The flocculant promotes the entering small flocs to form larger flocs through adsorption, electric neutralization and mutual bridging, and the action of the slow stirrer ensures that the medicament and the flocs can be fully mixed without damaging the formed large flocs.
The flocculated effluent enters the bottom of the inclined plate of the sedimentation tank and then flows upwards to the upper water collecting area, and particles and flocs are settled on the surface of the inclined plate and slide downwards under the action of gravity. The higher upward flow rate and 60-degree inclination of the sloping plate can form a continuous self-scraping process, so that the flocs cannot accumulate on the sloping plate. The sludge slides down along the surface of the inclined plate and is deposited at the bottom of the sedimentation tank, then a circulating pump conveys part of the sludge into the coagulation and flocculation tank, and the rest sludge flows to a sludge treatment system through gravity flow. The water after sedimentation is discharged from a water outlet distributed at the top of the inclined plate sedimentation tank, and can be collected by arranging a clean water tank.
The utility model has the following advantages: 1. mechanical coagulation and mechanical flocculation replace hydraulic coagulation and hydraulic flocculation, and the mechanical stirring makes the mixing of the medicament and sewage faster and more sufficient, so that the coagulation and flocculation effects are enhanced, and the medicament is saved.
2. According to the utility model, the upward flow inclined plate based on the 'shallow pool sedimentation' theory is added in the inclined tube sedimentation stirring zone, so that the floor area of the sedimentation zone is greatly reduced.
3. The utility model can separate SS solid suspended matters with high specific gravity (approximately 80 percent of the total SS content) to be directly precipitated in a sludge recovery area, reduce the amount of sludge passing through the inclined plate and reduce the occurrence of blockage of the inclined plate.
4. Because the utility model adopts the design of sludge reflux, the probability and density of flocculation are increased, the impact load resistance and sedimentation performance are greatly improved, and the ideal and stable effluent quality can be ensured even under the condition of larger hydraulic load.
