Description
Technical Field
The invention relates to the field of bacteria-algae reactors, in particular to a mobile light source bacteria-algae reactor and an operation method thereof.
Background
At present, with the continuous expansion of urban scale and the increase of population, the pollution of water environment becomes a big problem. The urban sewage is an important reason for water pollution of rivers and lakes at present and is one of main reasons for restricting sustainable development of many cities, so that the treatment rate of the urban sewage becomes an important sign for civilization of a region. At present, the treatment aiming at the sewage is mainly aiming at the eutrophication of the water body environment, and particularly the nitrogen and phosphorus removal of the sewage is an urgent problem.
Currently, sewage is treated by bacteria and algae aiming at sewage treatment, wherein the bacteria mainly comprise heterotrophic microorganisms, and the algae mainly comprise photoautotrophic microorganisms. The combination of the two can remove organic matters, nitrogen, phosphorus and other nutrient elements in the water. Therefore, in order to realize the symbiotic environment of bacteria and algae, meeting the requirement of the algae to acquire the required light energy becomes the key of sewage treatment. In the prior art, CN207159052U is that a filter screen is transversely arranged between an upper guide plate and a lower guide plate, an LED lamp is arranged above the filter screen of a microalgae reaction chamber, and a light source is arranged above the liquid level of a reactor; and prior art CN211664792U is that the pool body material of the aerobic-microalgae mixing pool 14 is preferably transparent material, specifically ordinary glass, toughened glass, organic glass or transparent plastic, so that the light source 16 provides sunlight for the growth of microalgae through the transparent material, and is arranged outside the reactor; and prior art CN109133540A placed the light source inside the reactor; in the prior art, when the sewage treatment water amount is large, the uniformity of contact between light and microorganisms cannot be effectively guaranteed when the light source is positioned above the liquid level of the reactor and outside the transparent reactor, and the heat preservation problem of the reactor is difficult to solve because the light source is arranged outside the reactor; and prior art CN109097248A discloses a movable light source device in a duct, in which it is provided that a light source is placed inside the duct, and is made movable. Although a movable concept is proposed, it is difficult to be applied in engineering in practical application, for example, firstly, if a driving mechanism for moving the light source is arranged in the pipeline, and if a power source is a wired source, a long cable for moving the light source will affect the motion of the light source and easily cause mutual winding interference among different light sources; secondly, if an electricity storage mode is adopted, frequent charging can be caused by long-distance movement, and great inconvenience can be brought to operation work; thirdly, pipelines of thousands of meters need to be arranged in a folding way, and an insulating layer needs to be arranged, so that the maintenance space of the electromagnet outside the pipeline is greatly limited, and the pipeline is very inconvenient; fourthly, the bacteria-algae reactor in the pipeline has higher difficulty in realizing aeration and exhaust, and oxygen and carbon dioxide carried by dissolved water are difficult to ensure the normal growth of the bacteria-algae system; fifth, the resistance to fluid transport over long pipes results in a large power consumption, increasing the cost of disposal. Therefore, the above-mentioned prior art has a large volume of the tank body when the amount of wastewater is large, and the effective irradiation range of a single light source is generally less than one meter because the light transmittance of water is reduced due to the growth of bacteria and algae. If the light source is external, the problem of light energy of a large-scale reactor cannot be solved; an internal light source, a very large number of light sources need to be arranged to achieve this. Meanwhile, the external light source can influence the heat preservation of the equipment, the internal excessive light source can cause difficulty in maintenance, and the fixed light source can easily cause overlarge local light irradiation intensity to inhibit the biological activity of bacteria and algae near the light source. Therefore, a new bacterial-algae reactor is needed to solve the above problems.
