Water treatment equipment

Abstract

The invention discloses water treatment equipment, which comprises a raw water tank, a primary sedimentation tower, an inclined tubing sedimentation room, a filtration room and an adsorption room. A water taking and filtering device is arranged inside the raw water tank. The device comprises a water taking tank and a fixed support. The bottom of the water taking tank is open and provided with grating, and the inside of the water taking tank is provided with a material filter layer. A water inlet pipeline is provided with an on-line flow detector, a coagulation-dosing device and a high pressure pump. The primary sedimentation tower comprises inner and outer towers and a sludge discharge channel arranged between the outer tower and the inner tower. Baffle plates which are tilted upwards are arranged in a relatively-crossed manner inside the inner tower. A sludge collecting device and an inclined tubing sedimentation device are disposed inside the inclined tubing sedimentation room. The middle part of the filtration room is provided with a filter layer. Multiple adsorption layers are arranged inside the adsorption room. Raw water at a water taking end can be preliminarily filtered, and turbidity of raw water is further reduced by the utilization of the primary sedimentation tower. Then, the raw water further flows through treatment rooms such as the inclined tubing sedimentation room, the filtration room and the like to reach the drinking water standard. The whole system has a compact layout and occupies a small area.

Description

technical field [0001] The invention relates to the field of water treatment equipment, in particular to water treatment equipment. 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 causes at least 20 million deaths in the world every year, s...

[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.
