Problems solved by technology

Conventional disinfection, such as liquid chlorine disinfection, chlorine dioxide disinfection, and sodium hypochlorite disinfection, is a good choice for disinfection. However, with the deterioration of water quality, it is often not enough to use too much single disinfectant for disinfection. On the one hand, The treatment efficiency of a single disinfectant is low, the effluent quality is difficult to achieve a more ideal effect, and the by-products in the water exceed the standard. customer needs

Embodiment 1

[0043] The invention discloses a smart collaborative disinfection method suitable for complex surface water treatment, which includes the following steps:

[0044] Potassium permanganate, chlorine dioxide, ozone-activated carbon, and sodium hypochlorite are added to the raw water, which is controlled by the Huate smart cloud platform to carry out intelligent collaborative disinfection.

[0045] The principle of this treatment method is: first, potassium permanganate is added for emergency treatment and chlorine dioxide is added for pre-oxidation treatment to remove algae, iron, manganese, chroma, smell and taste in the raw water, and promote flocculation. Secondly, the ozone-activated carbon is used to further treat the water body to further oxidize the water body and absorb impurities to remove reducing substances in the water. Finally, sodium hypochlorite is used for the main disinfection of the clear water tank to ensure that the microbial indicators and residual chlorine in...

Embodiment 2

[0060] Taking a successful application of water plant (2) as an example, potassium permanganate emergency treatment and chlorine dioxide are used for pre-oxidation treatment, ozone-activated carbon for advanced treatment, sodium hypochlorite disinfection combination process, and intelligent collaborative disinfection in the water plant. , the water treatment process is as follows figure 1 shown.

[0061] ① Potassium permanganate dosing design

[0062] Potassium permanganate dosing adopts a fully automatic potassium permanganate dosing system. The water plant is equipped with a set of fully automatic potassium permanganate dosing equipment. The maximum design dosage is 1.2mg / L, and the dosing concentration is 2%. The dosing point is set at the upstream position of the raw water inlet pipeline, and is controlled by the Huate smart cloud platform to automatically add water with the inlet water flow.

Abstract

The invention relates to an intelligent cooperated disinfection method applicable to complicated superficial water treatment. The method comprises the following steps: firstly, subjecting potassium permanganate to emergency adding, and adding chlorine dioxide for pre-oxidation treatment so as to remove algae, ferrum, manganese, chromaticity, smells, flavors and the like from raw water; secondly, subjecting the water to advanced treatment by using ozone-activated charcoal, and carrying out oxidation and impurity adsorption on the water; and finally, adopting sodium hypochlorite to main disinfection of a clear water basin, so as to ensure that factory indexes are qualified. The potassium permanganate, the chlorine dioxide, the ozone-activated charcoal and the sodium hypochlorite are appliedin a cooperated manner, so that the problem that a single disinfectant is insufficient in capability is solved, and the safety of water is ensured; and all online detected data can be transmitted to aWalt wisdom cloud platform which is used for carrying out operational analysis, cooperated linkage and comprehensive regulation and control. The method can achieve intelligent cooperated disinfectionof complicated superficial water treatment, the effect that indexes of factory water are completely qualified is achieved, and the intelligent cooperated disinfection method for complicated superficial water is worthy of extensive popularization.

Description

technical field [0001] The invention belongs to the field of water disinfection, and in particular relates to an intelligent collaborative disinfection method suitable for complex surface water treatment. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] With the acceleration of industrialization and population urbanization, the construction of corresponding environmental protection and pollution control facilities lags behind. A large amount of industrial wastewater and domestic sewage are discharged without effective treatment. In addition, agricultural non-point source drainage makes surface water The pollution of water sources is becoming more and more serious, and the ...
