Abstract
The invention discloses a biological-ecological complex sewage treatment pool, including a plurality of filter units, which are successively arranged. Every filter unit includes a pool body which is enclosed by an upstream retaining dam (1) on three sides and a downstream retaining dam (2) on one side and an effluent distribution channel (3) which is arranged on one lateral of the downstream retaining dam (2). The downstream retaining dam (2) is higher than the upstream retaining dam (1). And every pool body is successively equipped with an aquatic plant (4), a geological packing (5) and an outlet collecting pipe (6) from up to bottom. An export (61) of the outlet collecting pipe (6) stretches out to one lateral of the downstream retaining dam (2) and is communicated with the effluent distribution channel (3). Compared with the prior art, the invention fully absorbs and degrades organic pollutants in the sewage. At the same time, the biological packing is used for providing a vector for the microorganism reproduction growth in a biological-ecological system, which leads to the biological reaction between the organic pollutants in the sewage and the microorganism. A biological-ecological complex mode is realized to remove nitrogen and phosphorus in the sewage effectively.
Description
Technical field
The present invention relates to technical field of sewage treatment, relate in particular to and a kind ofly adopt the biological-ecological complex method, can effectively remove the treatment tank of nitrogen and phosphorus in the sewage.
Background technology
River water body eutrophication phenomenon is serious, a global day by day water environmental problems.In the water body of unhurried current, nutritive substances such as nitrogen, phosphorus can bring algae and waterplant hypertrophy, and cause the dissolved oxygen in the water body sharply to reduce, and cause fish kill.When body eutrophication is serious, also can cause the lake to be degenerated even the water body extinction.And present many sewage directly do not enter among the river course through just handling, and cause many city river eutrophication and pollute more seriously, and resource of water supply and city resident's life, living environment caused serious threat.Therefore, to the water body treating in nutrient laden in the city and with serious pollution river course, the Sustainable development of protection Urban Water Environment and realization Urban Water Environment is significant.
Summary of the invention
Technical problem to be solved by this invention is the treatment tank that provides a kind of at above-mentioned prior art present situation and adopt the biological-ecological complex method, can effectively remove nitrogen and phosphorus in the sewage.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: this biological-ecological composite sewage water treatment tank, it is characterized in that: include a plurality of filtering units of arranging in turn, wherein each filtering unit comprises three by the upstream checkdam, one side is by downstream checkdam pond body that surrounds and the water outlet distributing flue that is positioned at downstream checkdam-side, wherein, the height of downstream checkdam is higher than the upstream checkdam, and be disposed with waterplant in the pond body of each filtering unit from top to bottom, biologic packing material and water outlet header, the outlet of this water outlet header is stretched out in downstream checkdam one side and is connected with described water outlet distributing flue, and, in two adjacent filtering units, the water outlet distributing flue in the previous filtering unit is adjacent with the upstream checkdam of a back filtering unit.
Biological respinse for organic pollution materials in microorganism in the reinforcement biologic packing material and the sewage, body bottom, described pond can also have additional aerating apparatus, the air in the external world is input to continually the bottom of biologic packing material by aerating apparatus, can constantly replenish the required oxygen of biological respinse, accelerate the speed and the efficient of sewage purification.Described aerating apparatus can be simple aeration head, also can be the aeration tube that has aperture on the tube wall.
Sometimes have many impurity in the sewage, for guaranteeing that sewage can be smoothly enters into biologic packing material district below it by the waterplant district, described biologic packing material top can be provided with grid layer, be distributed with a plurality of permeable holes and planting groove on this grid layer equably, each planting groove bottom has a plurality of through holes, and described waterplant just is planted in the corresponding planting groove, like this, the part root of waterplant just can pass the through hole of planting groove bottom and enter among the described biologic packing material, and sewage is when the grid layer, impurity just is blocked on the grid, current just can enter in the biologic packing material district smoothly, and many strains waterplant is distributed on the biologic packing material district by grid layer equably and firmly, prevent that waterplant and biologic packing material are between overflow stage in the river course, are walked by flood erosion.Described grid layer can non-metallic material employing grid or grid brick and realizing.
For the current in the water outlet distributing flue also can be purified, the top of described water outlet distributing flue also can be provided with waterplant, and is concrete, also can adopt grid layer as above-mentioned mode to fix waterplant is set.
For guaranteeing the purification of the biological-ecological system in this filtering unit that fully obtained from the effusive current of water outlet header of each filtering unit, described water outlet header is good to be provided with valve, specifically can adopt following design: the exit of described water outlet header is provided with valve, this valve is controlled its keying by-valve positioner, and, the upper position of part thereon of the pool wall of described pond body is provided with a water level sensor that links to each other with described valve positioner, and described valve positioner is according to the signal of this water level sensor and the keying of by-pass valve control; During actual motion, when the intravital water yield in pond reach a certain height and touches water level sensor, illustrate that sewage has carried out contacting and having obtained sufficient purification with waterplant, biologic packing material fully, at this moment, valve positioner is received the signal of water level sensor and opens valve that the current that purified just flow into the water outlet distributing flue from the water outlet header.
Be the exactness of highest safety stage sensor detecting water level, permeable division board can be set around the described water level sensor described biologic packing material is kept apart, avoid biologic packing material to touch water level sensor and influence it and detect effect.
Compared with prior art, the invention has the advantages that: by waterplant and biologic packing material are set in the body of pond, root system by waterplant, to fully absorb degraded as organic pollution materials such as nitrogen, phosphorus in the sewage, simultaneously, utilize biologic packing material, for the growth of the microbial reproduction in biology-ecosystem provides carrier, and make in the sewage organic pollution materials fully and its generation biological respinse, realize biological-ecological compound mode, nitrogen in the sewage and phosphorus are effectively removed, and aquatic plants growth is good whole filtering basin environment better appearance; Simultaneously, a plurality of filtering units are provided with in turn, make in the upper level filtering unit effusive water purification proceed further purification among flowing into the next stage filtering unit, design very science, rationally; The present invention can directly be communicated with smelly water river course, utilize some existence conditionses in river course, realization biological-ecological complex method is handled sewage, and Technology is simple, can in original river course, build, have the province of occupation of land, the good advantage of denitrogenation dephosphorizing effect.
