The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
The embodiment provides a bacteria-algae coupled water treatment system, referring to fig. 1 and 2, comprising a pretreatment area, an aerobic bacteria treatment area and a microalgae treatment area, wherein the pretreatment area, the aerobic bacteria treatment area and the microalgae treatment area are sequentially communicated, and the microalgae treatment area is provided with a light lamp. After the water body is pretreated, the water body is sequentially treated by the aerobic bacteria treatment area and the microalgae treatment area, and carbon dioxide is generated by the aerobic bacteria in the process of decomposing organic matters in the water body so as to provide the microalgae with photosynthesis, and the microalgae photosynthesis can provide oxygen for the aerobic bacteria. Therefore, the embodiment establishes the bacteria-algae coupled water treatment system without aeration, and can be used for removing nitrogen and phosphorus from the water body with low cost and high efficiency and removing COD.
Specifically, the pretreatment area of the embodiment comprises a micro-filter 1 and a protein separator 2, the micro-filter 1 is provided with a water inlet, and a water body to be treated is pumped into the micro-filter 1 through the water inlet of the micro-filter 1 by a pump body so as to remove solid suspended matters with the particle size of more than 70 mu m in the water body. The water outlet of the micro-filter 1 is connected with the water inlet of the protein separator 2 through a pipeline, and a pump body can be arranged on the pipeline to pump the water filtered by the micro-filter 1 into the protein separator 2 so as to remove colloid, cellulose and protein in the water and adsorb fine suspended matters. Thus, the water treatment system of the embodiment performs preliminary treatment on the water body through the pretreatment area.
After the water body is subjected to preliminary treatment by the pretreatment area, the water body enters the aerobic bacteria treatment area for further treatment. The aerobic bacteria treatment area comprises a biochemical pool 3, and a water inlet of the biochemical pool 3 is communicated with a water outlet of the protein separator 2. The biochemical tank 3 is internally provided with activated sludge and aerobic bacteria such as nitrifying bacteria, bacillus subtilis, enterococcus faecalis and the like, the activated sludge is domesticated by the aerobic bacteria, and ammonia nitrogen and nitrite in the water body are converted into nitrate.
After the water body is treated by the aerobic bacteria treatment area, the water body enters the microalgae treatment area for further treatment. The microalgae treatment area comprises a microalgae distributor 4, the water outlet of the biochemical pond 3 is communicated with the microalgae distributor 4 through a pipeline, a microalgae cloth made of plant fibers is paved in the microalgae distributor 4, microalgae such as microalgae culture solution, chlorella, scenedesmus and the like are arranged on the microalgae cloth, and the illumination lamps are arranged corresponding to the microalgae distributor 4. The water body from the biochemical pool 3 enters an algae distributor 4 through a pipeline, microalgae are attached and grown on the algae cloth, nitrate converted by the aerobic treatment area is absorbed, and some fine particles are adsorbed, so that the denitrification and dephosphorization of the water body are realized.
Therefore, ammonia nitrogen and nitrite in the water body are converted into nitrate by using aerobic bacteria through bacteria-algae coupling and are absorbed and utilized by microalgae, so that nitrogen and phosphorus removal of the water body is realized. In addition, the aerobic bacteria generate carbon dioxide in the process of decomposing organic matters in the water body so as to provide the carbon dioxide for microalgae for photosynthesis, and the microalgae photosynthesis can provide oxygen for the aerobic bacteria, so that aeration is not needed in the aerobic treatment zone, and the cost is greatly reduced.
Specifically, in this embodiment, a plurality of groups of pipelines for transporting water from the biochemical pond 3 to the algae distributor 4 may be provided, for example, two groups of pipelines in fig. 1 are provided, each group of pipelines includes two branches, each branch corresponds to a plurality of algae distributors 4, one end of each branch facing the algae distributor 4 is provided with rotary spray heads 5, the number of the rotary spray heads 5 of each branch is equal to the number of the algae distributors 4, the rotary spray heads 5 are provided above the algae distributors 4, and water outlets of the rotary spray heads 5 face algae fabrics. Therefore, water flowing out of the biochemical pond 3 can be centrifugally thrown on the algae cloth by the rotary spray head 5 in a rotary way, so that the water on the algae cloth is uniformly distributed, and the effective treatment of the water body is realized.
The water outlet of the algae distributor 4 is connected with the collecting tank 6 through a pipeline, and the water body treated by the algae distributor 4 flows into the collecting tank 6, so that the water body with nitrogen and phosphorus removal is collected and discharged. The collecting tank 6 is provided with a water outlet end and a water inlet end, the water outlet of the algae distributor 4 is connected with the water inlet end of the collecting tank 6 through a pipeline, and large algae such as botrytis cinerea, feather alga, flame alga and the like are arranged in the collecting tank 6, and the large algae are uniformly distributed from the water inlet end to the water outlet end of the collecting tank 6, so that the large algae can be utilized to further adsorb surplus nutrient elements in water, and the denitrification and dephosphorization effects are improved. So far, the water treatment system of the embodiment utilizes aerobic bacteria, microalgae and macroalgae to establish a symbiotic system, realizes the efficient removal of nitrogen, phosphorus and COD, and obviously reduces the cost.
Further, a plurality of baffle plates 7 are arranged in the collecting tank 6, the baffle plates 7 are staggered from the water inlet end to the water outlet end of the collecting tank 6, and the arrangement of the baffle plates 7 prolongs the flow path of the water body in the collecting tank 6, so that nutrient elements in the water body can be fully absorbed by the macroalgae, and the denitrification and dephosphorization effects are further improved.
In addition, the baffle plate 7 is provided with a plurality of through holes, and the through holes on the baffle plate 7 are sequentially increased from the water inlet end to the water outlet end of the collecting tank 6. The fewer the nutrient elements in the water body near the water outlet end of the collecting tank 6 are, the more the nutrient elements meet the discharge standard, so that the increase of the aperture of the through hole is beneficial to accelerating the water body discharge speed.
The bacteria-algae coupled water treatment system is an energy-saving, effective and very environment-friendly sewage treatment system, and has excellent capability of synchronously degrading carbon, nitrogen and phosphorus in various aspects such as urban domestic sewage, farm cultivation wastewater and other industrial wastewater.
