Settling apparatus with intake water filtering unit for waterworks

Abstract

The invention discloses a settling apparatus with an intake water filtering unit for a waterworks. The settling apparatus comprises the intake water filtering unit, a primary settling tower and an inclined tube deposition chamber; the intake water filtering unit comprises an intake water tank and a fixing support, wherein the intake water tank is fixed on the fixing support, a bottom opening of the intake water tank is provided with a grating, and a filter material layer is arranged in the intake water tank; the primary settling tower comprises an inner tower and an outer tower, wherein the bottom of the inner tower is provided with a water inlet pipe connected with the upper part of the intake water tank, the wall of the inner tower is provided with upwardly-inclined baffle plates arranged in a relatively intersecting manner; and an inclined tube deposition unit is arranged in the inclined tube deposition chamber, the lower part of the inclined tube deposition chamber is communicated with the top of the inner tower, and the top of the inclined tube deposition chamber is provided with a water outlet pipe. According to the invention, since the intake water filtering unit is arranged at the water intake end of the settling apparatus, the settling apparatus is capable of effectively removing floating objects in water; meanwhile, the baffle plates are utilized to shorten the settling distance of impurities and accelerate the sedimentation rate of impurities; and after secondary deposition by the inclined tube deposition chamber, most impurities in water are removed.

Description

technical field [0001] The invention relates to the field of water supply treatment equipment, in particular to a settling device in a waterworks with a water intake filter device. Background technique [0002] Human activities will cause a large amount of industrial, agricultural and domestic waste to be discharged into the water, causing the water body to be polluted. At present, more than 420 billion cubic meters of sewage is discharged into rivers, lakes and seas every year in the world, polluting 5.5 trillion cubic meters of sewage. Fresh water, which is equivalent to more than 14% of the total global runoff, has become a major threat to human survival and safety, and has become a major obstacle to human health, economic and social sustainable development. According to a survey by world authoritative institutions, In developing countries, 80% of various diseases are spread due to drinking unsanitary water. Drinking unsanitary water kills at least 20 million people aroun...

[0002] Human activities will discharge a large amount of industrial, agricultural and domestic waste into the water, polluting the water body. At present, more than 420 billion cubic meters of sewage are discharged into rivers, lakes and seas every year in the world, polluting 5.5 trillion cubic meters of water. Fresh water, which is equivalent to more than 14% of the total global runoff, is becoming more and more serious. Water pollution has posed a major threat to human survival and safety, and has become a major obstacle to human health, economic and social sustainable development. According to the survey of world authoritative organizations, In developing countries, 80% of various diseases are spread by drinking unsanitary water, and drinking unsanitary water causes at least 20 million deaths in the world every year, so water pollution is called "the world's number one killer". , in the river water and sewage purification treatment, various forms of water treatment equipment are playing an important role, but the general water purification equipment requires that the influent turbidity is not high, for some water with high turbidity after general treatment It is often difficult to meet drinking water standards
