Description

A kind of Artifical aquatic

Technical field:

The present invention relates to sewage purification, ocean, lake, reservoir, river and the water quality that is suitable for eutrophication becomes the improvement of open water qualities such as bad fountain, fish pond, swimming pool.

Technical background:

Environmental problem more and more is subject to people's attention now, and environmental pollution is the significant problem that people are badly in need of solving.Solve environmental pollution and just must solve water pollution problem, world's waters overwhelming majority is subjected to the puzzlement of eutrophication at present, and the pollution of water body is more serious, is restricting development economic and society, therefore solves the body eutrophication problem and seems and become increasingly conspicuous.

Microbial film is defined as a kind of single or blended microbial population that is growing actively, and as set bacterium, protozoon, fungi and algae, it irreversibly is attached to a kind of active or inactive solid surface.Humic acid substance and microbial film change the absorption behavior of mineral grain consumingly, and this surface adsorption acts in the transition process of contaminated wastewater thing and plays decisive role.Organic pollutant can be decomposed into simple inorganics, carbonic acid gas and water under microbial process, but need consume a large amount of oxygen at decomposition course, and photosynthetic process is emitted oxygen, thereby changes the water body redox potential; There is the microorganism on the shell structure to absorb, adsorb and cut down its pollutant concentration by biology, perhaps changes the chemical form of pollution substance, thereby reduce the bioavailability of pollution substance, the containment algae grows by changing microenvironment.

Application number 98240240.6 utility models disclose the filler that a kind of biological process is disposed of sewage, it is formed by several circular rings horse dresses, use the partition identical to connect between the ring plate with the ring plate material, form the netted cylindrical of scallop hole more than, wherein, interior ring plate is conical, and the taper direction of adjacent ring plate is opposite, and the quantity of partition increases from the outside from coil to coil in filler middle part, the quantity that makes scallop hole also from coil to coil increases, to guarantee ideal specific surface area and voidage, basis is novel need not install, and need not change for a long time, voidage reaches 98%, be difficult for to stop up, the sewage allow compliance with emission standards of wherethrough reason can be widely used in the processing of industrial sewage and sanitary sewage.Its weak point is, complex structure, takes up an area of that the space is big, sewage will obviously flow and just can handle, and can't carry out in-situ treatment on the spot to the sewage of open water body.

Application number 88105471 inventions are about process for treatment of sewage by using artificial water plants in oxidizing ditches.Water (flow) direction in oxidation ditch, the Artifical aquatic made of the man-made fiber of several layers of transversely arranged some amount up and down.Microorganism a large amount of breeding by means of the fibrous bundle on the Artifical aquatic and the organic suspension in the sewage or solubility nutrition forms that one deck can absorb, the microbial film of decomposing pollutant.Its weak point is that the water body that requires to handle is a mobile, and requires dissolved oxygen levels very high, and the man-made fiber goods are still waiting further research to environmentAL safety.

Summary of the invention:

The purpose of this invention is to provide a kind of Artifical aquatic, this Artifical aquatic is made up of connection cord, purification blade, ball float and weight, and an end of connection cord is fixed on the ball float, and the other end is connected with weight, purifies blade and evenly is connected on the connection cord.The present invention can improve the quality that is subjected to eutrophicated polluted water, improves the transparency of water body, checks the outburst of " algal tufa ", promotes the recovery of species diversity in the waters, and making, laying and easy to maintenance are a kind of environment-friendly type water body purification reaction apparatus of cleaning.

In order to achieve the above object, the present invention adopts following technical scheme: a kind of Artifical aquatic is by being made up of connection cord, purification blade, ball float and weight, this Artifical aquatic is put into water body and is used, the length of connection cord is less than 200～300 millimeters of water depths, and an end of connection cord is fixed on ball float, and the other end is connected with weight, purify blade and adopt foam board, thickness is 3～30 millimeters, evenly is connected on the connection cord, and two distances that purify between the blade are 30～200 millimeters; Weight is made greater than 2 material by proportion, its weight can overcome purify blade and ball float in water buoyancy and sink to the bottom.

The present invention compared with prior art has the following advantages:

1, can improve the quality that is subjected to eutrophicated polluted water, improve the transparency of water body, the water body of eutrophication was significantly improved at 7～15 days, can make water body reach the requirement of consumable water of sight and amusement water quality standard in the short period;

2, for or be about to occur the water body of algae " wawter bloom ", the present invention can check the outburst of " algal tufa ";

3, the present invention also can promote the recovery of species diversity in the waters when improving water quality;

4, can directly be placed in the contaminated water body original position and improve water quality, without any need for power and energy, be a kind of environment-friendly type purification reactor device of cleaning;

5, can design some light fixtures or neon light on the outside framework of the present invention, can beautify the environment, and not influence device sewage treatment effect;

6, material source of the present invention is extensive, and making, laying and easy to maintenance can be widely used in the water body that is subjected to eutrophication pollution, and the improvement of water quality such as open water body such as lake, reservoir, river, fish pond, fountain and swimming pool is had same effect.

Description of drawings:

Fig. 1 is a kind of sewage in-situ refining plant structural representation.

Wherein: 1 is that connection cord, 2 is that ball float, 4 is weight for purifying blade, 3.

Embodiment:

Below in conjunction with accompanying drawing, the invention will be further described: a kind of Artifical aquatic is made up of connection cord 1, purification blade 2, ball float 3 and weight 4; This device is put into water body and is used, the length of connection cord is less than 200～300 millimeters of water depths, one end of connection cord 1 is fixed on the ball float 3, the other end is connected with weight 4, purify blade 2 and adopt foam board, thickness is 3～30 millimeters, evenly is connected on the connection cord 1, and two distances that purify between the blade 2 are 30～200 millimeters; Weight 4 is made greater than 2 material by proportion, its weight can overcome purify blade 2 and ball float 3 in water buoyancy and sink to the bottom.

The present invention is like this work: this device is put into water, and weight 4 sinks under water, ball float 3 and purify blade 2 and be evenly distributed in the water body because of buoyancy function, because the length of connection cord 1 is less than the degree of depth of water, ball float does not have upstream face.
