Embodiment Construction

[0014] As shown in Figure 1 and Figure 2, the present invention includes a turbidity sensor and a detection circuit electrically connected to the turbidity sensor, and also has a sewage treatment motor current measurement circuit, wherein the turbidity sensor is a structure of four tubes and two pairs of tubes, that is, using Four groups of photocouplers, after waterproof and sealing treatment, are set in groups of two at different depths in the water to be tested, and the two photocouplers in each group have the same depth and different distances, and the distance between each group of infrared light-emitting diodes and infrared receiving transistors 5 to 20 cm to ensure that the sewage flows between each group of infrared light-emitting diodes and infrared receiving triodes. In this embodiment, the infrared light-emitting diodes in the photocoupler are of the 5GLE type, and the infrared receiving triodes are of the 3DU21 type; the detection circuit has a central Processor U1,...

Abstract

The invention discloses a measuring apparatus for the sewage turbidity including the turbidity sensor, the detection circuit connected with the turbidity sensor and the current measuring circuit of the sewage treating electric engine connected with the detection circuit which the communication interface of the CPU is connected with the epigynous machine or the far-end monitoring system by the series interface module. The invention can measure the electronic engine working data and the sewage measuring data at a same time; also it can transfer in a far distance and has the revising function.

Description

technical field [0001] The invention relates to an environmental protection water measuring device, in particular to an environmental protection sewage specific turbidity measuring instrument. Background technique [0002] Turbidity is an important indicator used to measure the turbidity of water, and it is also an important basis for analyzing the degree of water treatment and purification. The turbidity meter is a detection device specially used to measure the content of insoluble particulate matter suspended in water. The existing sewage specific turbidity measuring instrument can only measure the sewage turbidity alone, but cannot monitor the working data of the sewage treatment motor while measuring the turbidity, and the shading of the floating objects on the sensor wall cannot be automatically measured With calibration, the accuracy of sewage turbidity measurement cannot be guaranteed, let alone the standard discharge of sewage, which is an important factor affecting ...
