Abstract
The invention relates to a device for inhibiting the growth of microbes in water treatment test nutrient liquid, which comprises a nutrient liquid tank and a support frame, wherein the support frame and the nutrient liquid tank are coaxial, the nutrient liquid tank is provided with a top cover in sealed connection, 2 to 4 ultraviolet lamp tubes are uniformly arranged at the upper part of the top cover, an electric stirrer is fixed on the support frame through a supporter, a stirring paddle of the electric stirrer extends into the nutrient liquid tank through the top cover, the top and the bottom of the nutrient liquid tank are respectively provided with a water inlet pipe and a water outlet pipe, the water inlet outlet pipes respectively extend out of the nutrient liquid tank, and uniform scales are arranged on the wall of the nutrient liquid tank. The device is used according to the following steps that: firstly, all medicine adopted by solution preparation is added into the nutrient liquid tank, and water with the required quantity is filled into the nutrient liquid tank; and the stirring is carried out until all medicine is dissolved, then, the ultraviolet lamp tubes are turned on, a water outlet valve is opened, and the nutrient liquid can be provided for a microbe water treatment device through the water outlet valve. The device effectively solves the problems that in the water processing test process, because the microbes grow in the nutrient liquid, liquid transmission devices (peristaltic pumps and lift pumps) are blocked, and the microbes enter a biological treatment system, so biological fillings are blocked, and the biological treatment system is influenced. The device has the advantages that expensive instrument equipment and medicine are not needed, the fund investment is greatly reduced, the method is simple to operate and easy to master, the time and the labor are saved, and the growth of the microbes in the nutrient liquid is completely inhibited.
Description
Technical field
The present invention relates to a kind of device that suppresses growth of microbes in water treatment test nutrient liquid, belong to water quality safety technical field.
Background technology
In engineering of water treatment design, need select preferably treatment process and confirm corresponding processing parameter according to handling object, these work all need a large amount of laboratory lab scales, pilot plant test to complete.In water treatment experiment, can complete test by actual true waste water (source water) on the one hand, on the other hand, a large amount of experiments can complete by simulated wastewater (source water).Adopt true waste water (source water) to complete lab scale, pilot plant test, need to sample in a large number from engineering site, transport in time and refrigerate, take time and effort, often do not adopted by water treatment worker.Therefore, current water treatment lab scale or pilot scale research, often all simulation of water quality sample in chamber completes by experiment, prepare in advance the nutritive medium containing the concentration of certain organism, inorganics and each yin, yang ion, then by peristaltic pump or other e Foerderanlage, nutritive medium is thrown and joined in reactor according to the amount of design or calculating.At present, the problem that water treatment worker has a headache most in research process is the growth question of microorganism in nutritive medium.Because the nutrition of the nutritive medium of preformulation is abundant, extremely suitable microbial growth, therefore microorganism grow very soon in nutritive medium, easily forms the cotton-shaped microbic mass of suspension.On the one hand, the cotton-shaped microbic mass of suspension can cause the obstruction of infusion set (peristaltic pump, lift pump), and can cause the obstruction of liquid meter, causes the concentration of business lower than expection.On the other hand, the cotton-shaped microbic mass forming can also enter in biological treatment system, causes the obstruction of biologic packing material, affects the processing efficiency of microbe treatment system.Especially in summer, higher temperature easily forms cotton-shaped microbic mass in nutritive medium, has not only directly caused the error of test, has increased more greatly the workload of under meter cleaning and biological device back flushing.In research in the past, researchist conventionally adopt to add the inhibitor of microorganism in nutritive medium or cryopreserved nutritive medium mode with microbial growth in inhibition nutritive medium.But the method that inhibitor adds has very large side effect to follow-up biological test, but also need medicament expense to use.Put into refrigerator to suppress microorganism growth, its method operates very inconvenient, is unfavorable for test in place.Therefore, be necessary to develop the device of the microorganism growth of nutritive medium in a kind of inhibition water treatment test simple to operate.
Summary of the invention
The object of this invention is to provide a kind of device that suppresses growth of microbes in water treatment test nutrient liquid.
Patent of the present invention is a kind of device that suppresses growth of microbes in water treatment test nutrient liquid, comprise nutrition liquid bath and the outer support coaxial with it, nutrition liquid bath has the top cover of airtight connection, 2～4 ultraviolet lamp tubes are evenly set above top cover, electric blender is by being supported and fixed on above outer support, the stirring rake of electric blender stretches into nutrition liquid bath by top cover, and the top of nutrition liquid bath and bottom are respectively equipped with water intaking valve and outlet valve, and nutrition liquid bath outer wall is provided with uniform scale.
Utilize the microorganism growth process of nutritive medium in patent inhibition water treatment test of the present invention as follows: the medicine first all water distributions being adopted drops in nutrition liquid bath, fixed roof, subsequently the stirring rake of electric motor is stretched in nutrition liquid bath by top cover, close outlet valve, open water intaking valve, to the water that injects required quality in nutrition liquid bath.Close subsequently water intaking valve, open electric mixer, be stirred to all medicines and all dissolve, turn off electric mixer, open subsequently ultraviolet lamp tube and open outlet valve, can provide nutritive medium to microorganism water treatment device by outlet valve.
Advantage of the present invention and positively effect: patent structure of the present invention is simple, easy and simple to handle.Whole device is placed on sterilizing and whipping process in a device and carries out, and has saved greatly the time of operation.And the present invention do not need expensive plant and instrument, medicine, greatly reduce fund input, time saving and energy saving, can suppress the microorganism growth in nutritive medium completely.
