Purification treatment method for natural water

Abstract

A natural water purification processing method includes two parts of direct purification treatment and bioremediation treatment. The direct purification treatment successively includes separating water, designing current generation, installing equipments, operating equipments to leads to the water flow and the upward floating of flocs which are formed after the reaction between colloidal substances and flocculants and cleaning scum at last until a natural water purification effect is achieved. The bioremediation treatment is in particular to implant biological agents evenly in the water body to lead to the self-purification function of the water body. Based on the direct purification treatment and assisted by the bioremediation treatment, the invention treats water comprehensively to improve the self-purification function of the water body, restore the ecological balance and keep the natural water body being a good natural landscape. The equipments of the invention are implanted in water to be operated. No installation site of the equipments has to be reconstructed and no land area is occupied. Therefore, the invention has the advantages of less investment, less energy consumption, low cost, high quality, high efficiency and fast purification rate.

Description

technical field [0001] The invention belongs to the technical field of ecological environment protection, and specifically relates to a method for purifying natural water bodies. The method comprehensively uses physical methods, chemical methods and biological methods in sewage treatment technology to treat natural water bodies so as to restore the self-purification function. The natural water bodies include landscape water bodies, closed and relatively closed water bodies such as river courses and ponds in cities, natural and artificial lakes, etc. Background technique [0002] With the general improvement of people's living standards, the requirements for the environment are getting higher and higher. Natural water bodies such as landscape water bodies in gardens and residential quarters, rivers, ponds in cities, natural and artificial lakes, etc. are places where people can relax. It is a good place for boating and leisure, but as the flow of people increases, the polluti...

Problems solved by technology

[0005] 1. Biological treatment: use biological bacteria agents with a certain water purification function to establish "metabolism" through the bacteria agents to purify the water body, but it takes a long time and environmental conditions to establish metabolism (generally 3-6 months), and due to the different degrees and properties of water pollution, it is difficult to achieve results with a single biological treatment, and even the bacterial agent is overwhelmed and has no effect

[0006] 2. Physical and chemical treatment: the use of physical methods such as sewage interception, water transfer, circulation, filtration, silt suction or clearing pond dredging has certain effects, but it requires the construction of many equipment and consumes a lot of energy, which is not only costly and expensive , for a l...
