Problems solved by technology

[0003] Among them, aquatic plants are limited by their growth characteristics, and have limited demand for nutrients during the growth period, and it is difficult to meet the removal effect of nutrients in the water body during the ecological restoration of surface water; and the growth is greatly affected by the season, especially in winter. Its effect on water purification can cause water quality instability and even rebound
After the aquatic plants complete a growth cycle, the withered plant stalks need to be harvested and disposed of, resulting in high operation and maintenance costs.
In addition, disperse and sprinkle aquatic animals. For mussels, they will be scattered at the bottom of the pool. In order to ensure their growth activity, they need to be equipped with water aeration equipment, and they can only purify surface water and subsurface water.
Thirdly, the construction cost of constructed wetlands is high, and subsurface wetlands are prone to filler blockage, compaction, short circuit, etc., with short service life and high operation and maintenance costs

Embodiment 1

[0083] This embodiment provides a clam and snail collaborative purification system for water environment treatment;

[0084] A river section in Wuhu City has a total length of 1.6km, a water surface width of 10-20m, an average water depth of 1.5-2m, and a water area of ​​about 20,000m 2 . The river section has implemented conventional water environment treatment measures such as sewage interception, sediment dredging, aeration and oxygenation, running water circulation, aquatic plant planting and aquatic animal release, and the previous black and odorous water body has been treated to a quasi-V water body. Its water quality indicators are as follows: transparency is 30-40cm, dissolved oxygen is 5-6mg / L, chemical oxygen demand is 40-50mg / L, total nitrogen is 1.5-2.5mg / L, and total phosphorus is 0.4-0.5mg / L .

[0085] On the basis of the above-mentioned conventional water environment control measures, a set of mussel and snail collaborative purification system will be set up a...

Embodiment 2

[0089] This embodiment provides a clam and snail collaborative purification system for water environment treatment;

[0090] Tail water purification wetland of a sewage treatment plant in Chuzhou City, the wetland covers an area of ​​40000m 2 , the treatment scale is 35,000 tons / day. The wetland adopts the underwater forest artificial surface flow wetland technology. There are 9 pools in total. At present, aquatic plant planting and aquatic animal feeding have been implemented. The current water quality of the tail water of the sewage treatment plant is better than the first grade. Standard A, the specific water quality indicators are as follows: dissolved oxygen is 7-8mg / L, chemical oxygen demand is 45-50mg / L, total nitrogen is 2.0-2.5mg / L, total phosphorus is 0.3-0.4mg / L, the current wetland The effluent water quality is IV-V water, and the specific water quality indicators are as follows: transparency is 60-80cm, dissolved oxygen is 7-8mg / L, chemical oxygen demand is 30-35m...

Abstract

The invention relates to a mussel-snail synergistic purification system for water environment treatment. The mussel-snail synergistic purification system comprises a shellfish bed, attached mussels and attached snails, wherein the shellfish bed comprises a support structure and silk screen platforms, the support structure is used for supporting and fixing the shellfish bed, the silk screen platforms are flatly laid and fixed on the support structure, and and at least two layers of silk screen platforms are arranged. The mussel-snail synergistic purification system provided by the invention not only can improve the transparency of a water body, but also can remove organic matters, nitrogen, phosphorus and the like in the water body. While the water is purified, ecological products can be brought by self growth and reproduction through extraction, and the system is an effective and valuable ecological technology. Through the metabolism of the mussels and the snails, nutrient substances such as organic matters, nitrogen and phosphorus in the water body are absorbed and utilized, so that pollution recycling and resource industrialization can be realized.

Description

technical field [0001] The invention relates to a water environment treatment system, in particular to a clam and snail collaborative purification system for water environment treatment. Background technique [0002] With the progress and development of society, a large number of external pollution sources have entered the surface water body, causing the surface water environment to be polluted to varying degrees, and even the water body is black and smelly. At present, in the surface water ecological restoration technology, the conventional technology is mostly planting aquatic plants on the basis of effective control of pollution sources, such as emergent plants, submerged plants, floating leaf plants and floating plants, etc., and then adding aquatic animals, such as fish Mussels, mussels, snails, etc.; in the tail water purification technology of urban sewage treatment plants, the conventional technology is mostly to build a constructed wetland after physical and chemica...
