A Method for Determining the Scattering Characteristics of Suspended Particles in Water

Abstract

The invention discloses a method for confirming the scattering properties of suspended particle matter in water. The method comprises the following steps: (1) firstly, establishing a detection device consisting of a scattered light generation unit, a scattered light acquisition unit and a scattered light analysis unit; (2) adding pure water into a water tank, and measuring by a laser power meter to obtain that the light power of emergent light passing through the pure water is 10; (3) adding turbidity water into the water tank, and measuring to obtain the light power T1 of the emergent light passing through the turbidity water, and the radius x of a scattered light spot; (4) calculating the scattering coefficient and the scattering angle of the turbidity water as shown in the specification, thereby obtaining the scattering property; and (5) respectively changing the concentration of particle matter, the wavelength of the emergent light, the sizes of the particle matter and the varieties of the particle matter, and repeating the steps so as to obtain the scattering properties in different situations. By the method, the scattering properties of suspended particles in domestic sewage and industrial wastewater can be accurately, simply and conveniently measured, the suspension states of suspended particle matter in a water body can be effectively controlled, and technical support is provided for turbidity influence reduction in water environment treatment.

Description

technical field [0001] The invention relates to sewage analysis technology, specifically a method for determining the scattering characteristics of suspended particles in water, and belongs to the fields of sewage treatment and solid waste treatment. Background technique [0002] In recent years, with the rapid development of my country's economy, the problem of environmental pollution has become increasingly serious, and water pollution has attracted people's attention because of its wide range of influence and is closely related to human survival and life. The contradiction between economic development and environmental protection has become increasingly prominent, and cases of local economic development at the expense of the water body (quality) environment in the basin have occurred from time to time. Water is the source of life, and the quality of water (quality) is closely related to human health. Therefore, water quality monitoring has attracted more and more attentio...
