Abstract

The invention discloses a waste water online biological monitoring method and a waste water online biological monitoring device, and belongs to the field of waste water online monitoring. The device consists of a circulating pump (3), a liquid storage chamber (2), a circulation chamber (1), an inductive electrode (4) and a multimeter (5); the circulating pump is arranged at the lateral bottom of the liquid storage chamber away from the circulation chamber, and is connected with the circulation chamber via a plastic pipe; the sidewall of the circulation chamber is connected with side surface of the liquid storage chamber at the equal height to realize flow exposure of the whole course. Two pairs of copper electrodes with nuts are arranged on the inner side of the circulation chamber, wherein one pair of the electrodes functions as an input end of an electrical signal, and the other pair of the electrodes is connected with the multimeter to form an output end of the electrical signal. The distribution of an electric field in the circulation chamber can be influenced by swimming of the tested organism daphnia, namely the change of output current or voltage. By the invention, whether the quality of the discharged water is safe can be intuitively reflected; meanwhile, an 'electronic eye' is provided for the pollution incident monitoring and the dispute resolution monitoring of an environmental monitoring department. The device disclosed by the invention is simple in structure and strong in mobility and can be used indoors and outdoors.

Description

technical field

[0001] The invention relates to a method and device for on-line monitoring of wastewater, more specifically to a method and device for on-line biological monitoring of wastewater. Background technique

[0002] Water is an indispensable and important resource in human production and life. On the one hand, in recent years, the total discharge of chemical wastewater in my country has always accounted for the first in the total discharge of industrial wastewater in the country, and has become a major problem of water environmental pollution in my country; among them, toxic organic compounds The problem of water pollution is particularly serious, mainly because many organic substances are carcinogenic, teratogenic, and mutagenic substances, which can cause tumors in animals, seriously affect human health and the growth of animals and plants, and then interfere and destroy ecological balance. On the other hand, due to the development of globalization, the increase o...
