Problems solved by technology

According to the regulations, these new substances must undergo relevant environmental aquatic organism toxicity evaluation before they are put on the market. However, at this stage, there is no aquatic organism test system for unstable substances that can meet the OECD, EPA and domestic registration test standards, so this test The device is designed and invented to fill this gap, and it can ensure that the concentration of the tested substance is within the range specified by the test standard during the test and remains uniform and stable.

Abstract

The invention relates to an automatic natural environment continuous waterflow simulation test device, which comprises a water conditioning system, a dilution table, a biological test culture cabinet, a temperature and illumination control system, a data monitoring and acquiring system, a wastewater collection system, a water storage system and the like. Compared with the prior art, the automatic natural environment continuous waterflow simulation test device has the advantages that the device is evidently effective in natural waterflow dynamic environment simulation, stable in long-time operation, high in safety, simple in regulation, high in automation level, easy to demount for washing and easy to replace. Whole-course automatic monitoring, tracking and recording of the whole test process by a computer can be realized, reliability and stability in operation of the long-term waterflow test can be guaranteed by the test device, and the test device is applicable to GLP (good laboratory practice) tests of short or long toxicity of various relevant aquatic organisms published by the OECD (organization for economic cooperation and development) and the EPA (environmental protection agency).

Description

technical field [0001] The invention relates to a simulation test device, in particular to an automatic simulated natural environment uninterrupted flow test device. Background technique [0002] With the expansion of China's chemical, pesticide and other consumer markets, and the rapid and vigorous development of the domestic pesticide industry, pharmaceutical and chemical industries, a large number of new pesticides, medicines and chemicals at home and abroad have been introduced or developed, including a large number of environmental unstable substance. According to the regulations, these new substances must undergo relevant environmental aquatic organism toxicity evaluation before they are put on the market. However, at this stage, there is no aquatic organism test system for unstable substances that can meet the OECD, EPA and domestic registration test standards, so this test The device is designed and invented to fill this gap, and it can ensure that the concentration...
