Problems solved by technology

[0004] The advanced treatment process of phosphorus and nitrogen removal is used to solve the problem of eutrophication in reclaimed water. Although it can reduce the nutrient salt in reclaimed water, the treatment cost is expensive
[0005] It takes a long time to solve the problem of eutrophication of reclaimed water by establishing a complete ecosystem in the landscape water body, and the manual maintenance and management are more complicated and the management costs are also high.

Embodiment 1

[0026] As shown in the figure, the submerged plant reaction device for controlling the eutrophication of reclaimed water according to the present invention includes a tank body 1 , a planting pipe 2 , a mesh 3 , and a supplementary light source device 4 . The tank body 1, the planting tube 2, and the mesh 3 are all transparent materials, and the mesh 3 is provided with pipe ears. The supplementary light source device 4 is immersed in the center of the tank body by a quartz tube or a glass tube covered with a fluorescent lamp, the planting tube 2 is arranged around the supplementary light source device 4 in the tank body 1, and the mesh 3 is arranged on the planting tube 2 position on both sides of the upper part.

[0027] The reclaimed water to be treated is taken from Tianjin TEDA New Water Source No. 1 Plant, and its reclaimed water pretreatment process is SBR+CMF. The turbidity of the regenerated water discharged through CMF is almost zero, but the content of nitrogen and p...

Embodiment 2

[0035] The submerged plant reaction device for controlling the eutrophication of regenerated water is the same as in Example 1, and its treatment method is:

[0036] (1) The above-mentioned submerged plant reaction device is connected with the regeneration pool, and 10 liters of TEDA regeneration water is added to the reaction device of the present invention from the bottom through a pump;

[0037] (2) put 50 grams of fresh weight more salt-tolerant grate-toothed spinach into the planting tube of 12 liters of reactor volume;

[0038] (3) Use natural light of 30,000 lux during the day, turn on the supplementary light source of 2,000 lux at night, and the temperature is 22°C;

[0039] (4) After the purified water stays in the reclaimed water treatment equipment for 5 days, it is discharged from the upper part of the regenerated water treatment equipment;

[0040] Using sarcocarp as water purification material, the removal rate of phosphate reached 99.7% and the removal rate of ...

Embodiment 3

[0042] The submerged plant reaction device for controlling the eutrophication of regenerated water is the same as in Example 1, and its treatment method is:

[0043] The regenerated water to be treated is taken from the pilot unit of the National 863 Membrane Bioreactor Project undertaken by Tianjin University. The treated water is the sewage discharged from swimming pools and bathhouses, which is reused for artificial water features on campus after being treated by membrane technology. The water quality of its regenerated water is characterized by high content of phosphorus and ammonia nitrogen, high pH and low salinity.

[0044] (1) The above-mentioned submerged plant reaction device is connected with the regeneration pool, and 10 liters of TEDA regeneration water is added to the reaction device of the present invention from the bottom through a pump;

[0045] (2) 50 grams of fresh weight of smilax are put into the planting tube of 12 liters of reactor volume;

[0046] (3)...

Abstract

A hydatophyte reaction system for preventing the eutrophication of reclaimed water is composed of tank body, light source, planting pipes surrounding the light source and nets. Its treating method includes such steps as communicating the system with reclaimed water pool, putting the hydatophytes in said planting pipes, culturing at 20-25 deg.C by light radiation for 3-5 days, and draining the treated water.

Description

technical field [0001] The invention relates to the field of reclaimed water treatment, in particular to reclaimed water treatment equipment and a treatment method for reusing landscape water bodies. Background technique [0002] Reuse of urban reclaimed water for landscape water is an important aspect of sewage resource utilization. In recent years, the practice of this aspect has developed rapidly in my country's economically developed coastal water-deficient cities. [0003] At present, conventional secondary treatment followed by continuous microfiltration (CMF) is commonly used at home and abroad for the reclaimed water treatment of landscape water bodies. The reclaimed water treated by such a process not only has almost zero turbidity, but also has a low bacterial content and has a good landscape effect. However, when the wastewater treated by advanced membrane technology is reused in urban landscape water bodies, there are potential dangers, that is, the reclaimed w...
