Abstract
The invention discloses a spirogyra-biomembrane ecological treatment system, and relates to a sewage treatment system. The invention solves the problems of high construction and operation cost and a low sewage advanced purification rate lying in the prior sewage treatment system. The spirogyra-biomembrane ecological treatment system consists of an oxidation pond and a culture pond, wherein the spirogyras and biomembranes are arranged in the oxidation pond; and the spirogyras are cultured in the culture pond. The method has high capability of removing nitrogen and phosphorus in the sewage, facilitates the advanced treatment of the sewage, has simple operation, and reduces the sewage treatment cost by 60 to 70 percent. Simultaneously the nitrogen and phosphorus enriched spirogyras can be used as fertilizers; therefore the system produces high economic efficiency.
Description
Technical field:
The present invention relates to a kind of Sewage treatment systems.
Background technology:
Along with the rapid raising of people's living standard and the acceleration of urbanization process, produced a large amount of sewage in the city and entered in the rivers, wherein nitrogen and phosphorus are seriously polluted, cause body eutrophication, water environment pollution serious day by day.At sewage treatment area, exist Sewage treatment systems at present and build and running cost high the problem that the advanced treatment of wastewater rate is low.
Summary of the invention:
The present invention builds and the running cost height in order to solve present Sewage treatment systems, and the problem that the advanced treatment of wastewater rate is low provides Confervoid-biomembrane ecological treating system.
Confervoid-biomembrane ecological treating system of the present invention is made up of the oxidation pond and the cultivation pool, be connected by pipeline between the oxidation pond and the cultivation pool, be furnished with the tender microbial film of water in the oxidation pond, the tender microbial film employing of water " on-down " combination, the water silk floss is arranged in waterborne of oxidation pond, and the water silk floss is fixed with the plastic grid support down, under plastic grid, vertically arrange microbial film, the water flow mode of oxidation pond goes out on advancing under being, cultivates to arrange in the pool and cultivate the water silk floss, and the water flow mode of cultivating the pool goes out on advancing under being.
The function of oxidation pond be purify waste water, enriched in nitrogen and phosphorus, the function of cultivating the pool is to cultivate the continuous and advanced treatment water body once more of the required water of oxidation pond.
Spirogyra can be fixed by the plastic grid support in large-scale thread living algae, is difficult for running off.
The water silk floss has good stain resistance and environmental compatibility.
Because the water silk floss consumes carbonic acid gas and discharges oxygen in process of growth, can provide oxygen for microbial film, strengthen the biological degradation of aerobic microbiological on the microbial film, reach sewage is carried out the advanced treatment purpose.The microbial film degradation of contaminant does not need aeration in the Confervoid-biomembrane ecological treating system of the present invention, reduces cost of sewage disposal 60%～70%, compares with conventional oxidation pond technology, does not need that secondary is carried out in water outlet and removes the algae processing, is beneficial to the advanced treatment of sewage.
Confervoid-biomembrane ecological treating system only is made up of the oxidation pond and the cultivation pool, and laid down cost is low.
In addition, the water silk floss also has the growth of the microalgae cell of inhibition, reduces the physiologically active of microalgae cell, can suppress the growth of miniature algae in the water body when disposing of sewage.
