Method for realizing online centralized intelligent injection control of sewage treatment reagents

Abstract

The invention provides a method for realizing online centralized intelligent injection control of sewage treatment reagents. According to the invention, a set of centralized injection control devicesis utilized; a plurality of sewage treatment reagents are designed to be centralized in a skid-mounted spill base and to be centralizedly placed on a foundation platform on site, so an occupied floorarea is greatly reduced and maintenance and management are more centralized and convenient. In particular, the method can realize both on-site and remote automatic online centralized intelligent injection control of a variety of sewage treatment reagents in the skid-mounted spill base, so the automation degree of the sewage treatment reagents is increased, and centralized control and storage of data such as running time, real-time flow, operating temperature, operating pressure, accumulated operating data and equipment outage states can be realized through intelligent control program and hardware in a control box. The method is very suitable for realizing remote online monitoring. A skid-mounted modularized integral structure enables factory manufacturing and long-distance transportation to be realized and also facilitates on-site installation and debugging.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a method for realizing online centralized intelligent injection and control of sewage treatment chemicals. Background technique [0002] Various chemicals such as redox agents, PH regulators, flocculants, etc. need to be added in the sewage treatment process. Since the dosing equipment for the above-mentioned various chemicals is placed at different locations in the water treatment field, the areas where the dosing equipment is placed are scattered, and the automatic The systematic dosing equipment results in a large footprint, and the scattered placement of dosing equipment makes maintenance and management very inconvenient. [0003] The self-contained dosing equipment is manually controlled and dosing, the degree of automation is low, and online and remote automatic adjustment of dosing cannot be realized. The dosage of various treatment chemicals is also completely re...

Problems solved by technology

[0002] Various chemicals such as redox agents, PH regulators, flocculants, etc. need to be added in the sewage treatment process. Since the dosing equipment for the above-mentioned various chemicals is placed at different locations in the water treatment field, the areas where the dosing equipment is placed are scattered, and the automatic The systematic dosing equipment results in a large footprint, and the scattered placement of dosing equipment makes maintenance and management very inconvenient

[0003] The self-contained dosing equipment is manually controlled and dosing, the degree of automation is low, and online and remote automatic adjustment of dosing cannot be realized. The dosage of various treatment chemicals is also completely recorded manually, which is easily affected by the subjective factors of the operator. Large accuracy is poor, and the working environment on site is poor

[0004] In addition, it is difficult to store data such as running time, real-time flow rate, operating temperature, operating pressure, accumulated operating data, and equipment outage status of self-contained dosing equipment, and it is difficult to realize remote monitoring
