Solar light coupling aquatic biological water purification pool

technical field

The utility model relates to a sunlight-coupled aquatic biological water purification pool, which belongs to the technical field of sewage treatment.

Background technique

my country is a country with a shortage of water resources, and more than half of the cities in the country are short of water. With the development of industrialization and urbanization, the discharge of industrial wastewater and domestic sewage continues to increase, resulting in the ecological deterioration of river and lake water quality, sludge deposition, and stench, which lead to a series of environmental problems. During the "Twelfth Five-Year Plan" period, the state should further promote energy conservation and emission reduction, promote enterprises to carry out clean production, make full and reasonable use of resources and energy, and further reduce the amount of wastewater discharge and pollution. With the continuous improvement of environmental standards, and It is required to upgrade industrial pollution treatment facilities and improve the treatment capacity of COD, ammonia nitrogen and total phosphorus in sewage treatment plants.

A large number of studies have shown that using plants and microorganisms to reduce COD content and absorb heavy metals and nitrogen and phosphorus has obvious effects, and has the characteristics of good effect, low cost and low energy consumption.

Chinese patent CN102303922A discloses a plant-benthic sewage purification device, the device is composed of a plant planting pool and a benthic animal pool, the tail water inlet is set at a high position at the front end of the plant planting pool, and the rear end of the plant planting pool is set at a high position The water outlet is also connected to the high-level water inlet of the benthic animal pool, and the rear end of the benthic animal pool is provided with a clear water outlet at a high position; the plant planting pool and the benthic animal pool are sequentially connected with lower heights along the water flow direction. The method includes vegetal decontamination and benthos decontamination. This patent is applied to the tail water purification of sewage treatment plants, where the lighting conditions of aquatic plants are not good enough, the number of plants is small, and the growth rate and absorption efficiency of nitrogen and phosphorus will be affected to a certain extent.

Chinese patent CN200810018736.6 discloses a method for forming an ecological pollution-cleaning compound riverbed ecosystem. It is characterized in that various substrates are arranged layer by layer on the new river bed from bottom to top to form a compound river bed. Aquatic plants are planted on the shoal of the compound riverbed, and the slope of the deep groove is protected by ecological concrete, forming an ecological system of compound riverbed of ecological pollution type. The advantage of this system is that it can form a "plant-matrix-microbe" comprehensive treatment system, and use aquatic organisms to inhabit and grow and river biodiversity to lay water distributors for advanced treatment of up-to-standard tail water. This patent is used for the advanced treatment of tail water, but the lighting conditions of aquatic plants are not good enough, and most of the aquatic plants are emergent plants with a single type of plant, which has certain restrictions on the absorption of nitrogen and phosphorus.

Contents of the invention

Aiming at the shortcomings existing in the prior art, the purpose of this utility model is to provide a vertically layered corridor-type sunlight-coupled aquatic biological water purification pool, which can improve the light factor of aquatic plants, promote the photosynthesis and growth of plants, and make Pollutants in sewage are quickly absorbed and decomposed by submerged plants and emergent plants, improving the purification effect of its water quality.

In order to achieve the above object, the technical scheme adopted by the utility model is as follows:

Solar light coupled aquatic biological water purification pool, including vertical layered corridor pool, concentrator, optical fiber, floating plants or potted emergent plants, plant pots, submerged plants, water inlet and outlet pipes, vertical layered gallery The corridor-type pool is divided into multiple connected corridors by the corridor partition wall. Each corridor is divided into multiple layers by partitions. The uppermost layer of each corridor is planted with floating plants or potted emergent plants. Submerged plants are planted; the optical fiber is symmetrically fixed on the corridor wall and connected to the concentrator, and the concentrator is arranged outside the vertically layered corridor-type pool.

After the sewage enters the pool, it flows along the separated corridor. The concentrator and optical fiber system guide the sunlight into the water, improve the underwater light intensity, and promote the photosynthesis and growth of the lower plants, so that the pollutants in the sewage are submerged. Plants and emergent plants quickly absorb and decompose, improving their water purification effect.

The floating plants or emergent plants include water hyacinth, sedge, reed, calamus, etc.; A submerged plant with strong water purification ability.

The implementation of the utility model can improve the light factor of the aquatic plants in the water purification pool, ensure and promote the growth of the aquatic plants in the water where the sunlight is not irradiated or the light is weak, and improve the purification effect of the submerged plants on the water quality; At the same time, due to the direct use of the solar light guide system composed of concentrators and optical fibers, there is no energy conversion, high energy utilization rate, no power consumption, and good energy saving effect.

Detailed ways

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.

Embodiment: As shown in Figure 1 and Figure 2, the sunlight-coupled aquatic biological purification pool with a treatment flow rate of 2m ³ /h consists of a vertically layered corridor type pool 1, a concentrator 2, an optical fiber 3, floating water plants or Potted emergent plants 4, plant pots 5, corridor partition walls 6, layered partitions 7, submerged plants 8, water inlet pipes 9 and water outlet pipes 10.

The overall size of the purification pool is 5 meters long, 3 meters wide, and 3 meters high. It is divided into 5 corridors evenly along the length, each corridor is 1 meter wide, and each corridor is divided into three floors, and each floor is 0.8 meters high. The layered separator 7 adopts a porous PVC board or other corrosion-resistant porous boards. The layered dividing plate 7 is installed on the support frame on the corridor wall. The uppermost layer of each corridor is stocked with aquatic plants such as water hyacinth or potted calamus, and the bottom two layers are filled with potted submerged plants such as Elodea. Optical fibers 3 are symmetrically fixed on the corridor wall with a distance of 0.5 m, and connected to the concentrator 2.

The sewage is introduced into the pool at the beginning of the first corridor and flows along the divided corridor until it flows out from the end of the corridor. The concentrator 2 and the optical fiber 3 guide the sunlight into the water, improve the light intensity underwater, and promote the photosynthesis and growth of the lower plants, so that the pollutants in the sewage are quickly absorbed and decomposed by the submerged plants and emergent plants, Improve the purification effect of its water quality.
