Tap water plant water treatment equipment with water getting and filtering device

Abstract

The invention discloses tap water plant water treatment equipment with a water getting and filtering device. The equipment comprises a raw water pond, a primary settling tower, an inclined-tube settling chamber, a filtration chamber and an adsorption chamber, wherein the raw water pond, the primary settling tower, the inclined-tube settling chamber, the filtration chamber and the adsorption chamber are connected in sequence; the water getting and filtering device is arranged in the raw water pond and comprises the filtration chamber and a water storage chamber connected with the filtration chamber; a filter screen is arranged in the filtration chamber; an on-line flow detector, a coagulation dosing device and a high pressure pump are arranged on a water inlet pipeline; the primary settling tower comprises an inner tower body, an outer tower body and a sludge discharge channel between the inner tower body and the outer tower body, and baffle plates which incline upwards are arranged oppositely in a crossed mode in the inner tower body; an inclined-tube settling device is arranged in the inclined-tube settling chamber; a filter layer is arranged in the middle of the filtration chamber; multiple adsorption layers are arranged in the adsorption chamber. The tap water plant water treatment equipment can perform primary filtration on raw water at the water getting end and further lower the turbidity of the raw water through the primary settling tower; the raw water flows through the inclined-tube settling device, the filtration chamber and other treatment chambers and then can basically reach drinking water standards; the whole system is compact in layout and occupies a small area.

Description

technical field [0001] The invention relates to the field of water supply treatment equipment, in particular to water treatment equipment of a waterworks with a water intake filtering device. Background technique [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 ...

[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 a survey by 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 terms of river water and sewage purification treatment, various forms of water treatment equipment are playing an important role, but general water purification equipment requires that the influent turbidity is not high, for some water with high turbidity after general treatment It is often still difficult to meet drinking water standards. In addition, due to the complexity of the water treatment process, the traditional integrated water supply and purification equipment has the defects of various unit structures and large land occupation.
