Early warning device for biomass with comprehensive toxicity in water

Abstract

The invention discloses an early warning device for biomass with comprehensive toxicity in water, which comprises a water distribution area, a detection area and a control area. The water distribution area consists of a sampling tank, a clear water tank, a three-way valve, a clear water valve, a sample feeding pump, a clear water pump, a culture solution and concentrated solution storage tank, trace elements, a vitamin concentrated solution storage tank, a pH (potential of hydrogen) buffer solution storage tank, a mixing and deoxidizing tank, a magnetic stirrer, a liquid adding control valve and an emergency water sample draining pipeline; the detection area consists of a microbial fuel cell detecting unit, a sample feeding and water distributing valve, a water distributing tube, a cleaning control valve, a microbial fuel cell water discharge pipe, a depositing tank, a microorganism backwash pump, a drain pipeline and a microorganism removing pipeline; and the control area comprises a monitoring control and warning system and a display screen. By the aid of the early warning device, online monitoring and early warning for comprehensive toxicity of the water can be realized, and the early warning device has the advantages of long service life, high interference resistance and sensitivity, wide monitoring range, simplicity in daily management, low running expense and the like, and is applicable to monitoring emergency toxicity of water in conventional and emergency modes.

Description

technical field [0001] The invention belongs to the field of environmental monitoring, and in particular relates to a water quality comprehensive toxicity biological early warning device. Background technique [0002] With the rapid development of our country's industrial level and the rapid improvement of people's living standards, environmental pollution, especially water pollution, has become one of the major problems our country is currently facing. According to the statistics of the environmental protection department, the nine major water systems in the country have been polluted to varying degrees, most of which are quite serious, directly threatening the ecological environment of the water body and the normal life of the people. Collective poisoning incidents caused by water pollution are often reported in the newspapers. Therefore, it is of great significance to detect the leakage or discharge of toxic pollutants in time and effectively, and to carry out rapid warni...

Problems solved by technology

However, biosensors based on microbial respiration and luminescence characteristics, which are widely used at present, limit their applications due to problems such as large errors and susceptibility to interference.
