Water supply treatment system and method based on dosing flocculation precipitation

Abstract

The invention relates to a water supply treatment system and method based on dosing flocculent precipitation. The water supply treatment system based on dosing flocculation precipitation comprises a water inlet pipeline, a dosing flocculation water inlet channel, a mixing tank, flocculation tanks and a precipitation tank, mechanical stirrers are arranged in the mixing tank and the flocculation tank, the flocculation tank is connected with the precipitation water inlet channel, and the precipitation water inlet channel is connected with the precipitation tank through a pipeline; a manual waterinlet gate is arranged at the inlet end of the pipeline, and a rectifying grid plate is arranged after the pipeline enters a settling zone. The system has the beneficial effects that the mechanical flocculation treatment efficiency is high, the flocculation effect is good, the influence of water quantity change is avoided, the water yield per unit area is large, and the adaptability to water temperature and water quality change is high. The flocculation tanks are arranged according to stages and are separated by partition walls, so that water flow short circuit is avoided, and the stirring strength is gradually reduced along with the growth of flocculate. The sedimentation tank has strong adaptability to impact load and temperature change; and the planar arrangement is compact.

Description

technical field [0001] The invention relates to the field of feedwater treatment, in particular to a feedwater treatment system and method based on dosing, flocculation and sedimentation. Background technique [0002] Many regions of the world are facing the worst water scarcity. According to the statistics of the World Bank, 80% of the countries and regions in the world lack fresh water for civil and industrial use. According to the statistics of the United Nations, by 2025, two-thirds of the world's population may face water shortages, so water treatment technology will receive more and more attention. [0003] From the perspective of water resources, my country is a big country, but the distribution of water in various regions of our country is not perfect. The distribution of water in various regions is not only uneven, but also the construction of water supply is very lagging. On the whole, the water supply in many cities is in serious shortage, and the water-scarce c...

[0003] From the perspective of water resources, my country is a big country, but the distribution of water in various regions of our country is not perfect. The distribution of water in various regions is not only uneven, but also the construction of water supply is very lagging behind.

On the whole, the water supply in many cities is in severe shortage, and the water-scarce cities account for more than 1 / 2 of the country. At the same time, another major problem is the hidden danger of water safety.

People's health is generally threatened due to poor water quality; some cities lack regional considerations in the construction of water supply projects, resulting in redundant construction and waste of resources
