Problems solved by technology

[0008] However, large-scale landscape water bodies (artificial lakes and rivers) are completely different from the above two types of water. They blend with nature and receive the influence of natural climate, surrounding environment and human activities on it. A large amount of organic matter and organisms are produced in the environment, such as: ammonia nitrogen, algae, microorganisms, etc., the above-mentioned water treatment technology, when performing landscape water treatment, it exposes many problems that the system is not suitable for, and its water quality is difficult to achieve the expected goal

Embodiment 1

[0040] Embodiment 1, a kind of landscape water treatment process,

[0041] The first step: the landscape water in the landscape water body first passes through the dosing head and then enters the water pump; among them, the dosing head injects the flocculant delivered by the dosing device into the landscape water, and then uses the water pump to make the medicine and the landscape water fully Mix to get a mixture of medicine and landscape water;

[0042] Step 2: The field energy sterilizing algae sterilizer processes the mixed liquid output from the water pump, kills the bacteria, microorganisms and algae in the mixed liquid, and degrades the organic pollutants in the landscape water;

[0043] The third step: after the first step and the second step, the flocculant in the mixed solution fully coagulates with the impurities in the landscape water, and forms alum flower-like micelles together with the residual bacteria and algae; Then pass through a PC automatic filter with a f...

Abstract

The invention relates to a water treatment process, which in detail is a process of treating landscape water. It comprises following steps: feeding landscape water into water pump through medicine dosing port; medicine dosing injecting medicine from medicine dosing device into landscape, mixing medicine with landscape water; killing the bacteria, microbe and algae and degrading organic pollutant in the mixing liquid by using disinfecting and algae removal device, the medicine and foreign matter in mixing liquid coagulating and forming colloidal cluster with bacteria and algae; filtering with PC automatic filter with the filtering precision being equal to or less than 50 um, back flushing by using pressure difference, discharging through discharging port, and feeding treated water into landscape river. The invention is characterized by simplified process and no secondary pollution.

Description

technical field [0001] The invention relates to a water treatment process, in particular to a landscape water treatment process. Background technique [0002] Landscape water bodies (artificial lakes, rivers) have been developed in recent years with the continuous improvement of people's living conditions, followed by the pollution and deterioration of the water quality, which must be treated, thus forming the field of landscape water treatment. Prior to this, water treatment was basically divided into two major areas: [0003] Water purification treatment: mainly domestic water, industrial pure water, medical water treatment, etc. This type of water treatment technology can meet the standards of drinking water purification and industrial pure water. Its standard requirements are high, and the required cost is also high. It is too wasteful to do landscape water treatment, and it does not meet the actual situation. For example, the process of using water purification treatm...
