Technical Field

[0001] The utility model relates to the field of environmental protection water treatment, in particular to an ecological water treatment system. Background Art

[0002] Eutrophication refers to the phenomenon of water pollution caused by excessive content of nutrients such as N and P in water bodies.

[0003] In the prior art, the ecological engineering principle is adopted for eutrophic water bodies to degrade COD, nitrogen and phosphorus in water. That is, taking aquatic plants as the main body, using the principle of soilless cultivation technology, using high molecular materials, etc. as carriers and substrates, and applying the symbiotic relationship between species, making full use of the spatial ecological niche and nutritional ecological niche of water bodies, so as to establish an efficient artificial ecosystem to reduce the pollution load in water bodies.

[0004] For example, in a Chinese patent: an irrigation planting system, with the application number CN201520997281.2, which provides an irrigation planting system including a water storage tank and a water pump. The irrigation planting system further includes a water storage container and a planting container arranged on the water storage container. The planting container is provided with a water inlet hole, and the water storage container is provided with a drain hole; the drain hole is communicated with the water inlet of the water storage tank, the water inlet hole is communicated with the water outlet of the water pump, and the water inlet of the water pump is communicated with the water outlet of the water storage tank. However, the purification ability of this solution is limited and there is still room for improvement. Summary of the Utility Model

[0005] A series of simplified concepts are introduced in the summary of the utility model. These simplified concepts are all simplified from the prior art in this field, which will be further described in detail in the specific implementation part. The summary of the utility model does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the protection scope of the claimed technical solution.

[0006] The technical problem to be solved by the utility model is to provide an ecological water treatment system that can fully purify eutrophic water bodies, beautify the environment while reducing the manufacturing cost and saving the floor space of the purification system.

[0007] To solve the above technical problem, the utility model provides an ecological water treatment system, including: a primary water purification unit and a secondary water purification unit;

[0008] The primary water purification unit is formed as an independent water purification unit at least planted with first aquatic plants, which receives the effluent from the sewage treatment equipment, filters it and then transports it to the secondary water purification unit;

[0009] The secondary water purification unit is formed as an independent water purification unit in which at least the second aquatic plants are planted, and filters the incoming water and then outputs it.

[0010] The term "independent" means that there is no common area between the primary water purification unit and the secondary water purification unit, and they do not affect each other. The primary water purification unit and the secondary water purification unit can be adjacent or far apart, and the water purification transmission is achieved by setting a pressurization device (pump).

Under conditions that allow, such as when the position of the secondary water purification pool is lower than that of the primary water purification pool, the purified water can flow naturally by gravity and the first pressurization device does not need to be set. The situation of the second pressurization device is the same, and it is determined whether to set it according to the destination of the purified water output.

[0018] Preferably, further improving the ecological water treatment system, the primary water purification unit includes:

[0046] 2. The water purification tank of the present utility model can be recycled by using the fiberglass tank on the waste water purifier, turning waste into treasure and reducing costs.

[0047] 3. The water purification tank of the present utility model is installed in the enclosure wall of the secondary water purification pool. While the equipment is installed in a concealed manner, it does not occupy space, which is conducive to improving the system integration degree.

[0048] 4. The primary water purification unit and the secondary water purification unit of the present utility model can be independently arranged and set at different positions according to needs. The system combination is flexible and has strong applicability.

[0049] 5. The preferred solution of the present utility model introduces the combined use of water purification equipment (such as water purification sand and gravel, water purification tanks, etc.) and aquatic plants, which can form multiple filtration channels. Therefore, the requirement for the water purification ability of aquatic plants is reduced.
