Abstract
The invention relates to an in-situ ecological restoration technology suitable for tidal inland river. Aiming at the problems that the urbanized tidal river net slow flow riverway and pond at Peral River Delta are serious in pollution and the pollution is hard to govern, a water pollution direct purification or on-site treatment system suitable for three-side hard riverway and internal lake (both coats are concrete or mortar stone land wall) is developed. The system is further suitable for other similar river or riverway and urban internal lake. The system is installed at the bottom of the riverway, the front section or each of the front end and the rear end is provided with a slow flow settling zone, the middle section is a biological treatment zone; the biological treatment zone comprises a sinking caisson (fixed at the bottom of the river), a jet stream or pushing flow aerator and distribution equipment; the sinking caisson is made of angle steel and reinforcing steel bar, a plastic geonet is added on the inner wall, a polyurethane-based netty and block type biological carrier is mounted in the geonet. The specific setting and system construction is as shown in the figure. The aeration debugging is performed after the system is established, and then the system can operate according to design parameters after achieving an ideal condition. The proper efficient microbial flora can be added in the debugging process according to water quality and treatment effect requirement, so that the domestication effect is better.
Description
Technical field
The present invention is a kind of river bed formula water pollution direct purification or biological treatment system on the spot.The technical field related to comprises: biological catalytic oxidation, high-performance bio carrier technique, high-effective microorganism technology, jet or plug-flow aeration process, and pollutent physical sedimentation and river training works technology etc.
Background technology
Delta of Pearl River Development of Urbanization is rapid, river water body is seriously polluted, especially the inland river in area, river is netted, affect by outer Jiang Chaoxi and sluice, water body exchanges not smooth, and sewage is back and forth gone around in river course, in addition " linearize " in river regulation process and " three light " processes, make the river that this has polluted, seem even more serious, turn black smelly.In order to seek the resolution of economical and efficient, Guangdong and Hongkong of Guangdong Province essential domain key breakthrough project for bidding, " tidal waterway water pollution comprehensive repair technology and engineering mimoir " project (numbering: 2006A35102001) is classified as emphasis, and the present invention is one of the technology in conjunction with the research of this project development.
At present, in known river course, water pollution direct purification or treatment in situ technology have: 1. in river course or river course be close to side set up the engineering being similar to sewage work; 2. increased the catalytic oxidation area in river course by Ecological Measures, thus improve the natural purifying ability in river course; 3. common biological floating island technology (being only applicable to slow flow water bodies); 4. shed high-effective microorganism directly in river course, thus improve the technology of river course detergent power; 5. the direct technology etc. installing aeration facility in river course additional.These technology all in various degree there is certain not enough or defect, as: low to the removal efficiency of pollutent, investment is large, running cost is high and maintenance management inconvenient with can not continue, and affect the basic function such as to control flood and drain flooded fields in river course.
Summary of the invention
In order to overcome prior art deficiency, the present invention is in conjunction with domestic and international biological catalytic oxidation, high-performance bio carrier technique, high-effective microorganism technology, jet or plug-flow aeration process, and river training works technology etc., carry out compound, integrated and optimization, make it under the prerequisite not affecting river flood control water drainage function, have Pollution Treatment Investment province, take up an area few (or substantially not taking up an area) and remove the much higher heavy function of pollutent efficiency or effect.The present invention is mainly for the water pollution governing problem of tidal mesh self adaptability city inland river, inland lake (concrete or cement laid stone masonry quaywall are manifestation), and the water pollution direct purification of development research or on the spot biologic treating technique.The present invention also can be applicable to other similar river or city inland river, inland lake etc.
The technical solution adopted for the present invention to solve the technical problems: whole system is arranged on bottom of river channel, the leading portion of system or rear and front end (for tidal waterway) are provided with unhurried current settling region, and interlude is biological treatment zone.Biological treatment zone comprises caisson (being fixed on river bed), jet or plugflow aeration machine and controller switching equipment.Caisson has angle steel and reinforcing bar to make, and inwall installs plasticity geonet additional, and the in-built polyurethane-base of geonet is netted, the high-performance bio carrier of block-type.Concrete setting and System's composition are shown in accompanying drawing.After system is built up, aeration is debugged, and after reaching perfect condition, runs according to design variable.According to water quality and treatment effect needs, in debug process, suitable high effective microbial community can be added, carry out domestication aftertreatment better effects if.
The invention has the beneficial effects as follows, reduced investment, occupation of land lack (or substantially not taking up an area), contaminant removal efficiency is high, do not affect original function etc. of controlling flood and draining flooded fields in river course simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the present invention is further described.
Fig. 1 is the plot plan of the present invention in tidal unhurried current river course.
Fig. 2 is system architecture of the present invention and schematic diagram.
In figure: (1)-caisson, (2)-carrier, (3)-aerator, (4)-inlet pipe, (5)-caisson bearing, (6)-weir bank, (7)-settling tank.
Embodiment
First need the interval taken to transform according to accompanying drawing native system, then according to accompanying drawing, " caisson " (1) of bio-carrier (2) and jet or plug-flow type aeration machine rotor (3) are housed, finally add distribution facility.After completing, carry out biological treatment system domestication and debugging according to biological sewage treatment engineering debug technology; According to water quality and treatment effect needs, suitable high effective microbial community can be added in debug process and tame, to obtain better effect.
