Embodiment 1

[0090] Such as figure 1 and 2 As shown, this embodiment provides a dynamic optimal scheduling system for sewage treatment facilities based on water quality and water quantity monitoring, the system includes a central control system, a monitoring system and an on-site control system;

[0091] The central control system is composed of PC processing equipment, data transmission equipment and data acquisition instrument; it is used for data collection and storage of on-site water quality, flow, water level and other monitoring equipment, and real-time analysis of data according to preset procedures, and on-site Control equipment for real-time control; at the same time, it can display, query, and output;

[0092] The monitoring system includes flow monitoring equipment, water level monitoring equipment, and water quality monitoring equipment; it is used for real-time monitoring of water quality, water level or flow in sewage treatment facilities;

[0093] The on-site control syst...

Embodiment 2

[0114] Take the regulation of the treatment of acidic high-concentration COD sewage in the A2 / O process section of a sewage treatment plant as an example. The process flow of its treatment section is as follows: image 3 shown.

[0115] At a certain moment of operation, the real-time information of the current of the current controllers 1~13 in the field control system are Ai1~Ai13 respectively, and the dosage of the alkaline reagent in the adjustment pool is recorded and controlled in the form of current, and the mixer 1 Stirring intensity of ~3, blowing air volume of blower 1, PAM dosage, operating power of water inlet control pump, opening and closing of water valve 1~2, operating power of water pump 1~2, opening and closing of sewage shut-off valve, emergency Start and stop of the pump; the water quality and water quantity online monitoring equipment in the on-site control system conducts real-time monitoring, including: the pH online monitoring equipment 1 in the adjustm...

Abstract

The invention provides a sewage treatment facility dynamic optimization scheduling system and method based on water quality and water quantity. The system and the method aim at providing an operationscheduling scheme with reduced cost for operation and management of sewage treatment facilities. The method comprises the following steps: changing an extensive sewage treatment operation mode into adynamic operation regulation and control mode capable of saving energy and reducing material consumption, and ensuring that a sewage treatment facility is in an optimal operation state to the greatestextent through monitoring data of water quality and water quantity. Besides, the system also reduces the load impact on the sewage treatment facility caused by the instability of the quality and quantity of incoming water, and prevents the situation that the water quality exceeds the standard and is discharged due to the instability of the quality of outgoing water of the sewage treatment facility, thereby reducing the risk of environmental protection supervision and punishment.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a system and method for dynamically optimizing and dispatching sewage treatment facilities based on water quality and quantity. Background technique [0002] For industrial enterprises that discharge waste water in our country, they all require that the waste water can be discharged only after the sewage treatment reaches the standard. Sewage treatment is an energy-intensive industry, and the cost of sewage treatment is an important cost expenditure for industrial enterprises. The environmental penalties caused by excessive sewage discharge are also the cost of pollution control for industrial enterprises. How to optimize the operation and management of sewage treatment facilities, save energy and reduce consumption, reduce treatment costs and avoid environmental protection penalties caused by excessive sewage discharge is an important content and goal in the process of sewage tre...
