Water treating equipment for waterworks

Abstract

The invention discloses water treating equipment for a waterworks. The water treating equipment comprises a water taking and filtering device, a filtering chamber and an adsorption chamber which are connected sequentially, wherein the water taking and filtering device comprises a water taking tank fixed on a fixing bracket, the bottom surface of the water taking tank is open, a grid is arranged on the bottom surface, and a filtering medium layer is arranged in the water taking tank; a filtering layer is arranged in the filtering chamber, the filtering chamber above the filtering layer is connected with a water inlet pipe connected with the upper part of the water taking tank, and the filtering chamber below the filtering layer is provided with a water outlet; multiple adsorption layers and a vertical water distribution pipe are arranged in the adsorption chamber, the upper end of the vertical water distribution pipe penetrates out of the adsorption layers and is connected with a water distributor, the lower end penetrates out of the adsorption layers, extends out of the adsorption chamber and is connected with the water outlet of the filtering chamber, and the lower part of the adsorption chamber is connected with a water outlet pipe. The water taking and filtering device is arranged at a water taking end, so that sediment at the water taking end can be filtered preliminarily, the filtering chamber and the adsorption chamber can remove other residual impurities and harmful substances in water through filtering, and the equipment also has better filtering removal effect on impurities such as iron, manganese and the like in water.

Description

technical field [0001] The invention relates to the field of water supply treatment equipment, in particular to a water treatment equipment for a water plant. 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...

[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". Chemical method is the most mainstream method in water treatment methods. Generally, water treatment methods mainly include several steps of reaction, precipitation, filtration and sterilization. After these steps, the raw water can generally meet the standard of drinking water, but the traditional purification Water technology is to do nothing to deal with some toxic and harmful substances in raw water that may cause major hidden dangers to human health although their content is low.
