Problems solved by technology

Since flocs may grow further as they pass through the sampling tube, this measurement does not reflect the true state in the sedimentation system
The above problems and very expensive price limit the application of PDA in sewage treatment industry
[0010] Many similar technologies are not suitable for direct wastewater treatment due to various issues such as reliability, maintenance, complexity, response time, cost, etc.
To date, there is no widely used product in the wastewater market that provides optimal control of monitoring and dosing of chemicals in primary treatment

Embodiment Construction

[0040] Such as figure 1 As shown, the detection system according to the present invention includes two parts, namely the optical probe 11 and the signal processing module 12 . The optical probe 11 includes a transmitting (illumination) optical fiber 111 and a receiving (reading) optical fiber 112 . The branch with the illuminating fiber 111 can be connected to the light source through a mechanical adapter, and is used to emit the light emitted by the light source into the medium to be detected. The light source can be, for example, an infrared light emitting diode with a center wavelength of 850 nm. The receiving optical fiber 112 is used to receive the light reflected by the medium, and can be connected with the photodiode through a mechanical adapter. At the detection end, the optical probe 111 can be directly used in practical applications, and can also be connected with specific mechanical components to achieve specific mechanical installations. The specific structure o...

Abstract

The invention relates to a detection system and a method, and a water processing system and a method. The detection system provided by the invention can be used for detecting the particle state in a medium. The detection system comprises an optical probe which comprises at least an emission fiber, wherein the optical probe is used for emitting light to the medium; at least two reception fibers used for receiving the light reflected or scattered in a reverse direction by the medium, wherein, when the detection is carried out by the detection system, at least the end portion of the optical probe is positioned in the medium; and a signal processing module which is connected to the optical probe, wherein the signal processing module is used for converting a optical signal from the optical probe for receiving the fiber to an electrical signal, and then determining the particle state in the medium based on the electric signal.

Description

technical field [0001] The invention relates to a detection system and method, in particular to a detection system and method capable of online detection of particles contained in a medium. The invention also relates to a water treatment system and method, in particular to a system and method which can detect the state of the particles contained in the water online and treat the water according to the detection result. Background technique [0002] The purpose of primary wastewater treatment is to remove or reduce suspended solids and other possible pollutants in raw water or sewage by sedimentation processes such as sedimentation or flocculation and by physico-chemical treatment. In many industrial sedimentation tanks (purification tanks), chemical reagents (coagulants and flocculants) are added to promote the coagulation of colloids, thereby accelerating the solid deposition process. The selection and dosage of coagulant and flocculant play an important role in the sedime...
