Reactor-type biosensor bod rapid tester

Abstract

The reactor-type biosensor BOD rapid measuring instrument belongs to a kind of water pollution monitoring instrument. It adopts an integrated control system combined with an inflow and outflow control system, and uses a computer integrated control system to integrate temperature sensors, liquid level probes, electrode probes, heating sheets, and magnetic sensors. Generator for integrated control. The liquid inlet and outlet control system is controlled by a computer integrated control system, which programs each process flow to realize automatic management and control. Precisely control the temperature in the reactor, so that the activity of microorganisms is always kept at the same level of water inflow, water outflow and aeration. The dissolved oxygen consumed in the reaction stage can be controlled at the same amount, and the stirring and aeration make the dissolved oxygen in the water reach equilibrium and dynamic equilibrium. The particle reacts with the organism, consumes the dissolved oxygen in the water, and further measures the corresponding BOD value by measuring the difference before and after dissolution. The measuring instrument is easy to operate, fast, accurate, and has high automation procedures. It can automatically display the number of measured BOD. It is easy to carry, has a wide range of applications, and has high efficiency.

Description

technical field [0001] The invention relates to a water pollution monitoring instrument, in particular to a reactor-type biosensor BOD rapid measuring instrument. Background technique [0002] With the rapid development of society and science and technology, problems such as chemical industry and environmental pollution have attracted the attention of countries all over the world. The discharge of chemical wastewater directly affects water pollution, which is related to human health and the survival of animals and plants. There are a wide variety of organic pollutants in water bodies, and it is difficult to measure the quantitative values ​​of various components separately. Therefore, Biochemical Oxygen Demand (BOD) is a comprehensive indicator that characterizes the degree of organic pollution. It has been widely used in the evaluation process. BOD represents the amount of dissolved oxygen consumed by the organic matter in the water body under the action of microbial oxid...

AI Technical Summary

Problems solved by technology

At present: the BOD value in the water sample is mainly measured by the 5-day 20°C culture method in foreign countries and China, which is recorded as BOD 5 However, this method has many disadvantages, such as long measurement period, complex operation, poor reproducibility, large interference, not suitable for on-site monitoring, etc., and: the existing measurement methods use biofilm as a sensitive element, making There is an irreconcilable contradiction between biomass and biofilm thickness. From the perspective of detection sensitivity, more biomass is required; from the perspective of mass transfer, it is desirable that the biofilm is thinner. Therefore, the measurement results of traditional BOD sensors Unstable, poor reproducibility, not widely used

In the same industry in China: scientific research units and enterprise scientific and technological personnel are constantly researching, exploring, and improving the structure of the reactor-type biosensor BOD rapid detector, and there is an urgent need for a simple, accurate, fast, high degree of automation, and wide application Although some progress has been made in technology, there are still technical difficulties that have not been overcome in practical application. It is hoped to develop a reactor-type biosensor BOD rapid detector with high stability and high accuracy.
