Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a sewage sediment purification device. Background Art

[0002] Sewage refers to the discharged water from life and production that is contaminated to a certain extent. Water that has lost its original use function is simply called sewage. Sewage is caused by the incorporation of new substances into the water or due to changes in external conditions, resulting in the deterioration of the water and the inability to continue maintaining its original use function. Untreated sewage contains a large number of harmful substances, such as heavy metals, organic substances, pathogens, etc. If directly discharged into the natural environment, it will seriously pollute rivers, lakes and groundwater, and thus affect the health of the entire water ecosystem. Through sewage treatment, these pollutants can be effectively removed and the degree of pollution to water resources can be reduced.

[0003] After retrieval, the sediment purification device disclosed in the Chinese patent with the application number CN202322055667.9 adopts the method of static sedimentation. After the sewage on the upper side of the sediment is pumped out, there will still be a lot of water in the sediment. Subsequently, it is necessary to perform water treatment on the sediment again, resulting in a significant increase in the cycle of the entire sewage sediment purification, a significant increase in the treatment cost, and an impact on the efficiency of sewage treatment. Therefore, through a simple installation structure, it is possible to conveniently separate the sewage by sedimentation, improve the efficiency of sewage treatment, reduce the treatment cost, and its practical effect is good, worthy of promotion and use in the existing market.

[0004] When the above sewage sediment purification device purifies sewage, it is convenient for the sedimentation and separation of sewage. During the use process, the separated sludge is discharged by using a spiral blade. Since there is a gap distance between the above spiral blade and the discharge port of the sedimentation frame, and the sludge has a high viscosity, when the sludge is discharged, it is easy to block the pipe orifice at one end of the sewage discharge pipe due to the high viscosity of the sludge, making it difficult to reach the spiral blade for discharging. Therefore, due to the poor fluidity of the sludge, the sewage discharge pipe is blocked, making it difficult to discharge the sludge, and it is easy to damage the discharge pipe by the sludge, increasing the maintenance cost and reducing the sludge discharge efficiency of the sediment purification device.
