Description
Technical Field
The utility model belongs to the technical field of sewage treatment and specifically relates to a biological rotating disk to black smelly water river course in city is administered to sewage treatment field, especially, specifically is a black smelly water river course in city.
Background
The urban black and odorous water body problem is one of the most main water environment problems at present, the black and odorous water body in urban built-up areas above national level is counted and published, and the 'water pollution prevention and control action plan' requires that the black and odorous water body in the urban built-up areas is controlled within 10% in 2020 and is eliminated in 2030, so that the treatment of the urban black and odorous water body is urgent.
According to related researches, the black and gray color of the black and odorous water body is mainly formed by ferrous sulfide, manganese sulfide and other metal sulfides in the water body, and the odorous smell is mainly caused by hydrogen sulfide, methane and other gases. The main reason for causing the black and the odor is that the organic matters in the water body are seriously polluted, a large amount of dissolved oxygen in the water body is consumed during degradation, the concentration of the dissolved oxygen is lower than 2.0mg/L, the nitration reaction is inhibited, the concentration of ammonia nitrogen in the water body is generally higher than 8mg/L, and finally the black and the odor substances are formed.
At present, the treatment modes aiming at the urban black and odorous water body mainly comprise a physical method, a chemical method and an ecological restoration method. Common physical methods include aeration, water diversion and scouring, wherein the aeration is to increase water-gas exchange through an aeration system to improve dissolved oxygen in a water body, the water diversion and scouring is to introduce a water body with better water quality into a black and odorous water body to dilute and replace the black and odorous water body, and the sediment dredging is to remove polluted sediment deposited at the bottom of a river channel by a mechanical means.
The chemical method mainly comprises the step of adding chemical reagents such as flocculating agents, phosphorus removal agents and the like to remove suspended particles, nutrient elements and the like in the water body. The ecological restoration method mainly uses carriers in the forms of artificial wetlands, floating beds and the like to purify water by aquatic plants and microorganisms attached to root systems of the aquatic plants.
In the above existing measures for treating black and odorous water, the physical method only treats the phenomenon, the water diversion and flushing are periodically performed, the quantity of sediment dredging engineering is large, the construction is greatly limited by the surrounding conditions of the river, the dredged polluted sediment is difficult to treat, and the aeration method can improve the content of dissolved oxygen in the water, but the aeration methods such as impeller and jet flow can violently disturb the water during aeration, release a large amount of gases such as hydrogen sulfide into the air, and cause the odor of the air around the river. Although the chemical method has obvious effect, the cost is high, and some chemical reagents can cause secondary pollution to the environment, so that the chemical method needs to be used carefully.
Use the ecological remediation method in urban river course often to receive great restriction, do not have the bank side soil of large tracts of land and can plant constructed wetland, current shore protection is mostly concrete structure, if change into ecological bank protection, the cost is expensive, simultaneously because black and odorous water is in comparatively serious pollution degree, the aquatic plant growth on the floating bed can receive the atress, lead to unable high-efficient absorption conversion pollutant, other microorganisms in aquatic plant root system and the river course also can be because dissolved oxygen content problem, use anaerobic microorganisms to give first place to, the purifying effect of aerobic microorganisms to the water has been weakened greatly, the floating bed also can produce the choked flow when the river course floods simultaneously and influence.
Application publication No. is CN102206016A discloses a hierarchical formula black and odorous river water purification method in the patent, through directly throwing different types of microorganism, lets its growth on artificial medium, purifies the water, but unable normal position is used in black and odorous river course, will additionally increase the basin, simultaneously, need increase power in two, tertiary purification groove and carry out the aeration, the filler carrier can produce certain choked flow in the river course, leads to the fact certain influence to safety when the flood discharge.
Patent with publication number CN205472949U discloses a portable mobile slow-flow riverway water body treatment device, which can float on the water surface and treat the water body by using fillers such as a biological rotating disc, but is limited by the characteristics and volume of the device, the treatment capacity is small, the water body needs to be lifted in the device system, the energy consumption is large, the aerobic area has no way of supplementing oxygen, the high dissolved oxygen content is difficult to keep continuously to maintain the aerobic reaction, and the device floats on the water surface to influence the flood drainage of the riverway.
