Chemical dosing device and method for sewage treatment system

Abstract

The invention discloses a chemical dosing device and method for a sewage treatment system. The chemical dosing device comprises a tank body, a mounting plate, a limiting block and a feeding pipe, wherein the mounting plate is arranged on a side face of the tank body; the limiting block is arranged at the bottom of the mounting plate. The chemical dosing device disclosed by the invention has the beneficial effects that a servo motor drives a stirring roller to rotate and chemicals can be stirred; a feedback control circuit composed of a temperature sensor, a control host and an electric heatingplate can be used for keeping heat of the chemicals in the device to a pre-set temperature value, so as to prevent the chemicals from being caked in a chemical storage process; meanwhile, the plurality of devices can be spliced through grooves and bulges, so that various chemicals are added; a feedback control circuit composed of a flow sensor, a control host and a solenoid valve can be used forautomatically controlling a chemical dosing amount to a pre-set value; meanwhile, the chemical amount in the tank body can be monitored in real time through an infrared camera and is displayed on a display screen, so that utilization functions of the device are enriched and the device is easily popularized and utilized in a large range.

Description

technical field [0001] The invention relates to the technical field of auxiliary devices for sewage treatment systems, in particular to a dosing device and method for sewage treatment systems. Background technique [0002] With the rapid development of the economy, the pressure of water shortage is increasing. People finally realize that the water consumption in society exceeds the range that the natural cycle can carry. People are more and more aware of the importance of rational use of water resources. , only by fully respecting the law of the natural cycle of water resources, realizing the multiple recycling of water resources, and maintaining the cycle balance of water resources is an effective way for the sustainable use of water resources, and the wide application of sewage treatment systems is the key to the sustainable development of society Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, ...
