Description
Technical Field
The utility model relates to a sewage treatment field especially relates to an integrated device of algae substance sewage is contained in processing.
Background
The eutrophication problem of water bodies such as Chinese lakes, reservoirs, rivers and the like exists in different degrees, more than 60 large lakes have the eutrophication phenomenon reported by literature data, and 30 percent of reservoirs face the same eutrophication threat. The drinking water sources such as the honeycomb lake, the Taihu lake, the Dian lake and the like and various lakes have serious algal blooms in summer and autumn, and the algal blooms are seven to eight months every year. The explosive growth of algae not only affects the water landscape, but also causes the deterioration of the water ecological environment, so that the algae loses the self-cleaning capability. If eutrophic water is used as a water source for water, on one hand, a large amount of algae cells enter a water treatment system to cause a great deal of adverse effects on the operation of the process, and on the other hand, the algae toxins released by the algae cells cause serious damage to the health of human bodies.
At present, scholars at home and abroad mainly study and apply physical algae removal technology, chemical algae removal technology and biological algae removal technology aiming at the problem of algae removal in eutrophic water. Physical algae removal techniques are often used as emergency measures for algae removal, but the removal of algae is inefficient and labor intensive. The chemical algae-removing technology mainly removes algae by adding chemical agents for removing algae, such as chlorine, chlorine dioxide, ozone, potassium permanganate and the like into the existing treatment equipment, but the chemical algae-removing technology is easy to generate secondary pollution, and a large amount of algae toxins are released into a water body in the process of killing algae cells to directly threaten the health and safety of human beings and animals. The biological algae removal technology mainly aims at the water body with serious eutrophication, adopts the processes of biological contact oxidation and the like, can simultaneously remove pollutants such as algae, organic matters, ammonia nitrogen, odor and the like, but has long operation time, slow effect and high cost for removing the algae.
At present, a plurality of air-float algae removal treatment schemes are provided for removing algae in eutrophic water. The air floatation is a typical solid-liquid separation technology, and meanwhile, the algae cells exist in water in a suspension state, so that the microbubbles are introduced into the algae-containing water body, the adhesion and the floating of the microbubbles and the algae cells are facilitated, and the effect of removing algae by the air floatation is achieved. However, the efficiency of air flotation to remove algae is related to the surface properties of the algae material; the surfaces of the algae cells have more active sites which can act with functional groups on the molecular chains of the coagulant and the flocculant, and can interact with the active functional groups of the coagulant and the flocculant to generate certain adsorption acting force, and the adsorption acting force connects the algae and the flocculant (flocculation) agent molecules together, so that the algae particles are destabilized. However, some water plants directly perform air floatation treatment, so that certain kinds of algae have low affinity with air bubbles and are not easy to adhere to the air bubbles, and the air floatation treatment has poor removal effect. In addition, under the condition of high turbidity, some algae with large specific gravity are not easy to float by air floatation, and are directly discharged after air floatation treatment to influence the quality of the discharged water. The air floatation algae removal also has the problems of difficult treatment of algae removal slag, easy blockage of a releaser and the like.
