Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sludge water treatment in water purification plants, in particular to a combined wastewater recovery drainage and sludge discharge pool. Background Art
[0002] A certain amount of wastewater is generated in the production process of water plants. The wastewater mainly comes from the sludge water of sedimentation tanks and the backwash wastewater of filter tanks. The pollutants of the sludge water of water treatment plants mainly include suspended solids, organic impurities, algae in the raw water, and chemical precipitates formed during the treatment process. The pollutants of sedimentation sludge water mainly include metal hydroxides formed by coagulants, sediment, silt, and other inorganic and organic substances. The characteristics of backwash wastewater are low mud concentration and large drainage volume. If the sludge water and backwash wastewater are discharged into rivers and lakes without treatment, it will cause serious pollution of the water body, siltation and raise the riverbed, affecting the navigation and flood discharge capacity of rivers. Direct discharge of wastewater is also a waste of water resources.
[0003] Wastewater recovery tanks and sludge discharge tanks are very important facilities in the sewage treatment process. They play a key role in environmental protection and water resource reuse. However, traditional wastewater recovery tanks and sludge discharge tanks also have some obvious shortcomings in actual operation, which affect the water purification effect and water resource utilization rate to a certain extent. First, the wastewater quality of traditional wastewater recovery tanks is poor, which will affect the raw water treatment of water plants. Since the wastewater in the wastewater recovery tank contains a high concentration of pollutants, the consumption of reagents in the treatment process increases, thereby increasing the treatment cost of the water plant. At the same time, poor water quality may also cause problems such as blockage and corrosion of treatment equipment, shorten the service life of the equipment, and increase the maintenance frequency. Secondly, the wastewater in the sludge discharge tank cannot be reused, resulting in a waste of water resources. During the operation of traditional sludge discharge tanks, the wastewater in the sludge is discharged to the sewage treatment plant or river. These water resources could have been reused after proper treatment. However, due to the limitations of the sludge discharge tank design, these wastewaters cannot be effectively recovered and utilized, which not only wastes precious water resources, but also may pollute the environment.
