Water purifying device used in tap water plant

Abstract

The invention discloses a water purifying device used in a tap water plant. The water purifying device comprises a water taking and filtering device, a primary sedimentation tower, an inclined tube settling chamber and a filtering chamber which are sequentially connected, wherein the water taking and filtering device comprises the filtering chamber and a water storage chamber connected with the filtering chamber, a water inlet is formed in the front end of the filtering chamber, a filtering screen is arranged inside the filtering chamber, a fixed support is arranged on the bottom of the water storage chamber, and the water storage chamber is connected with the primary sedimentation tower through a water inlet pipe; the primary sedimentation tower comprises an outer tower body and an inner tower body with the bottom connected with the water inlet pipe, and upward inclining baffle plates are oppositely arranged in the inner tower body in a cross mode; an inclined tube settling device is arranged in the inclined tube settling chamber, the lower portion of the inclined tube settling device is communicated with the top of the inner tower body through a water pipe, a water distribution pipe communicated with the top of the inclined tube settling chamber is arranged on the top of the filtering chamber, and a water outlet pipe is connected to the bottom of the filtering chamber. The water taking and filtering device is arranged at the water taking end, impurity sedimentation distance is shortened by means of the baffle plates, impurity sedimentation speed is increased, and raw water can basically meet the drinking water standard after being subjected to sedimentation-filtration through the inclined tube settling chamber and the filtering chamber.

Description

Technical field [0001] The invention relates to the field of water supply treatment equipment, in particular to a water purification device of a waterworks. Background technique [0002] Human activities will cause a large amount of industrial, agricultural and domestic waste to be discharged into the water and pollute 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 waste. 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 the sustainable development of human health, economy and society. According to a survey by a world authority, In developing countries, 80% of various diseases are spread by drinking unsanitary water. Drinking unsanitary water causes at least 20 million deaths worldwide every year. Therefore, water pollution is calle...

[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
