Description

A biological water purification device with symbiosis of algae and bacteria

technical field

The utility model belongs to the technical field of environmental protection equipment, and in particular relates to a water purifying device for algae and bacteria symbiotic organisms, which is used for purifying river and lake water bodies, and is especially suitable for purifying eutrophic water bodies. the

Background technique

Due to the aggravation of population concentration and urbanization, water pollution has been exacerbated, and the unorganized discharge of a large amount of domestic wastewater has led to eutrophication of lakes, rivers and other water bodies, which has become a common phenomenon. In recent years, water body eutrophication is very common in our country. So far, 90% of the lakes in our country have been or tend to be eutrophic. Local waters may often cause blue-green algae outbreaks due to eutrophication of water bodies, resulting in algal blooms. As people continue to increase pollution control and ecological restoration of lakes and rivers, the ecological environment of lakes and rivers has gradually improved, and different types of aquatic organisms have gradually recovered. However, the nutrient level of the water is still high, which makes the quality of the water environment unavoidable. To improve, it is of great significance to restore the balance of aquatic ecosystems, purify water quality, promote the development of fisheries, and use in-situ ecological methods to restore water bodies. the

At present, there is no very effective method to eliminate water eutrophication. The existing water eutrophication treatment can be mainly summarized as physical, chemical and biological methods. Because the first two methods generally have high cost, unstable effect and easy to produce secondary Due to secondary pollution and lack of sustainability, people have paid special attention to bioremediation technology. According to the different main organisms, biological methods can be divided into microbial remediation technology mainly using beneficial microorganisms and phytoremediation technology mainly using large vascular submerged plants. Among them, phytoremediation technology has become the most ideal choice for bioremediation of eutrophic water because of its safety, cheapness, easy manual operation, and certain environmental aesthetic value. However, there are still many limitations in practical applications that make it difficult to apply effectively. the

Contents of the invention

The purpose of the utility model is to provide a biological water purification device with simple structure and convenient use, which is especially suitable for the symbiosis of algae and bacteria in the treatment of eutrophic water bodies. the

The purpose of this utility model is achieved like this: comprise floating tube, nylon net, fixing cable tie and stay rope, described floating tube is spliced and formed into a rectangle, utilizes fixing cable tie to fix nylon net on each floating tube Then connect a stay rope at the corner of the frame formed by the floating pipe, and then fix the stay rope along the coast. the

The utility model adopts the space enclosed by the nylon net and the floating pipe as the growth place of microorganisms, algae and floating water plants, utilizes the growth and absorption of the algae and floating water plants to remove excess nitrogen and phosphorus in the water, and purifies the water quality. The equipment is simple in structure and easy to operate, and can be applied to ecological restoration and water purification projects of rivers, lakes and other water bodies. the

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings, but the utility model is not limited in any way, and any transformation done based on the teaching of the utility model all falls within the protection scope of the utility model. the

As shown in the figure, the utility model includes a floating tube (1), a nylon net (2), a fixed cable tie (3) and a pull rope (4). The nylon net (2) is fixed on the pipe by fixing cable ties (3), and then a pull rope is connected at the corner of the frame formed by the floating pipe (1), and fixed on the river bank (5). the

The floating pipe (1) is a UPVC pipe with a pipe diameter of 50mm and a wall thickness of 2mm-3.7mm. the

The nylon net (2) is braided by polymer material, the diameter of the rope is 1mm, and the mesh aperture is 1.5-3cm. the

The fixing tie (3) is a nylon tie with a width of 5mm and a length of 400mm. the

The stay cord (4) is made of nylon material with a diameter of 0.6-1.0cm. the

The described biological water purification device with symbiosis of algae and bacteria can be combined and used in multiple units to meet the purification requirements of larger water areas. the

Working principle of the present utility model: algae plants generally have pigments for photosynthesis, and can use light energy to synthesize organic matter from inorganic matter for their own needs. They are a type of self-supporting original plant plants that can live independently; Small floating plants such as duckweed are suitable for growing in still water. They can effectively absorb and utilize inorganic nutrients such as nitrogen and phosphorus in the water body for their own life activities, so as to achieve the purpose of removing excess pollutants in the water. At this time, the biological water purification device adopting a symbiosis of algae and bacteria of the present utility model actually provides an excellent growth place for suitable algae and floating plants, and can effectively prevent them from spreading out and causing pollution. the

The nylon net in the device of the utility model is woven from polymer materials, and is an excellent biological filler, which can provide attachment and growth sites for microorganisms, and firmly fix a large number of beneficial water purification microorganisms and enzyme preparations on the carrier On the one hand, it creates very suitable environmental conditions for the physiological activities of microorganisms, so that pollutants can be degraded rapidly. The organic pollutants in the water body are digested and decomposed by microorganisms into inorganic salts, which can be absorbed and utilized by algae and floating plants, and the root system of floating plants can also become a good growth place for microorganisms, and can produce oxygen to promote the reproduction of microorganisms. Those who can achieve the effect of synergistic water purification. the

The floating tube can prevent the proliferation of algae and floating plants, and the algae and floating plants can be effectively salvaged by pulling the rope regularly, thereby inhibiting the eutrophication of the water body and achieving the purpose of purifying the water body. the

The working process of the utility model: first determine the area and water depth of the lake, and according to the water quantity in the target area, the designed consumption, the unit water purification device can be arranged in series. The floating pipe and nylon net are installed on the shore, then put into the water, and fixed on the shore by a pull rope, while plant collection and salvage work can be carried out. After salvaging algae and floating plants, dry and dehydrate the salvaged plants and dispose of them properly. After the plants on the nylon net are salvaged once, the algae and floating plants can grow for a period of time, and there will be a process of enriching the pollutants in the water. When an obvious accumulation is formed, the next salvage work will be carried out, which is conducive to improving the salvage efficiency. And to reduce costs, the operation cycle is generally 7-15 days. the

The utility model has the characteristics of simple technology, high purification efficiency, low investment, good ecological benefits, and easy popularization and application. It can be applied not only to ecological restoration and water purification projects in rivers and lakes, but also to purification and maintenance of farming water for farmers. It is conducive to the increase of aquaculture production, the removal of nitrogen, phosphorus, and organic pollutants in the water body, the acceleration of the purification efficiency of the water body, the suppression of the eutrophication of the water body, and the prevention of secondary pollution of the water body after the corruption of aquatic biological residues, providing fish Such as spawning and breeding places to maintain the benign state and balance of the aquatic ecosystem, strengthen the ecological self-purification function of the water body, and improve the value of biodiversity and landscape aesthetics. the
