Abstract
The invention discloses an urban river purification treatment system which comprises an interception tank, an adjusting tank, a contact oxidation tank, a flocculation sedimentation tank, upper-level purification vegetation, lower-level purification vegetation, a filtration sedimentation tank and a reservoir, wherein the interception tank comprises an interception structure, the interception structure is detachably connected with the interception tank, an acid-base throwing device is arranged on the periphery of the adjusting tank, cellular elastic filler is filled in the contact oxidation tank, and a flocculating agent throwing device is arranged on the periphery of the flocculation sedimentation tank. The purification system for urban river treatment combines mixed reaction, biological purification and vegetation purification, has low cost and high sewage treatment efficiency, and the treated river sewage can be directly discharged into a downstream river and used as drinking water after purification or used as industrial water for enterprises.
Description
Technical Field
The invention relates to the technical field of river treatment, in particular to an urban river purification treatment system.
Background
With the development of urban scale and economic society, urban river channels are polluted to different degrees. The problems of incapability of living some aquatic organisms and even fishy smell caused by mixing of some aquatic organisms, such as turbidity, perennial dryness, less clear water, more water in the clear water, eutrophication and the like exist in some riverways with different degrees, a long time and a large amount of economy are spent, the bank can be turned green, the landscape can be beautiful, the water can not be clear due to great difficulty in improving the water quality, the embarrassing situation of beautiful landscape and sewage occurs, and the satisfactory effect is difficult to achieve.
As a large amount of pollutants are directly or indirectly discharged into surface water bodies such as rivers, lakes and the like in cities and towns, the oxygen consumption organic pollutants, nitrogen and phosphorus contents of the water bodies are high, the eutrophication of the water bodies is serious, so that the water bodies reach a black and odorous state, and aquatic plants such as blue algae, water hyacinth, water peanuts and the like are subjected to explosive reproduction, so that the water environment of the water bodies is seriously polluted, and the water ecological degradation of the water bodies is accelerated. The serious deterioration of the urban surface water environment not only affects the sustainable development of urban economy, but also seriously affects the healthy life of citizens. Effective treatment of urban polluted surface water becomes an important task which needs to be solved urgently in various places, and related treatment technologies become the first requirement.
At present, the methods for treating the surface water mainly comprise the following steps: firstly, a physical method: a method for capturing and recovering pollutants from polluted water bodies by utilizing dredging, filtering, settling, stirring and the like, and the method has the defects that the equipment scale is large, and the sludge and the like generated by purification treatment need secondary treatment; II, a chemical method: the method for oxidizing, reducing, adsorbing, condensing and neutralizing pollutants in water by using chemical agents has the defects that the added chemical agents can generate secondary pollution and need to be frequently added for many times to generate a continuous effect, and the cost is high: thirdly, biological method: such methods are generally classified into two categories, one is to utilize plants to absorb and degrade pollutants in water, such as: plants are planted in the ecological floating island, the method has the defects that the plants absorbing pollutants need to be cleaned regularly, otherwise, secondary pollution is caused by overgrowth of the plants, the method utilizes the algae inhibiting effect of algae pathogenic bacteria and the fungus cracking effect to remove the algae, and although the method is the most ideal method for quickly purifying the polluted surface water body of the town at present, the method has the defects that: the culture process of the thallus is complex, time-consuming and labor-consuming, and because the thallus is thrown too widely and has no pertinence, the purification treatment effect is not ideal.
Disclosure of Invention
The invention mainly solves the technical problem of providing an urban river purification treatment system, which combines mixed reaction, biological purification and vegetation purification, and has the advantages of low cost and high sewage treatment efficiency, and the treated river sewage can be directly discharged into a downstream river and used as drinking water after purification or used as industrial water for enterprises.
