Description
Technical field
The present invention relates to a kind for the treatment of apparatus of rainfall runoff.
Background technology
The most cities of China there will be the situation of waterlogging in rainy season, especially even more serious in rainy south.Along with urbanization process is accelerated, a large amount of hard grounds, building roof have replaced the ground with penetrating power, cause rainwater to enter pipe network by runoff, and pipe network is impacted, and occur the situation of a large amount of waterloggings.If pipe network is implemented the long-term beyond doubt complexity of transformation, dropped into huge engineering, also difficulty has obvious effect in a short time.If but part rainfall runoff is collected and utilized, not only can reduce the impact of rainfall runoff to pipe network, greatly alleviate discharge pressure, improve the situation of city waterlogging, can also play water-saving object.At present, the key that rainwater utilization is carried out in restriction is that administrative staff think that treatment facility needs special maintenance, and operation cost also can increase, and uses inconvenience, safeguards complicated.Southern area is due to rainy, rainfall is shorter interval time, except the with serious pollution underlying surface Rainwater Qualities such as motor road are poor, other hard underlying surface rainfall runofves major pollutants after 10 minutes are chemical requirement (COD), solid suspension (SS), turbidity etc.Administrative staff think that treatment facility complexity needs special messenger to safeguard on the one hand, cause the enthusiasm of rainwater utilization not high; On the other hand, except initial rainfall, a large amount of hard underlying surface rainfall runoff water quality is better, and rainwater utilization potentiality are large.How device for treating rain water being simplified, reduced operating cost, can control major pollutants again, guarantee water quality treatment amount, is the key that advances rainwater catchment system.
The existing patent application that rainfall runoff is processed mostly is simple solid-liquid separator, needs periodic maintenance, and the effects of purification quality after the device processes of automatic backwash is limited, for example:
China Patent Publication No. CN102614688A discloses a kind of rainwater runoff pollution treatment facility with self-cleaning function, this treatment facility is only the precipitate and separate to rainfall runoff, takes up an area greatlyr, and clean-up effect is limited, be mainly used in pollution more serious, the rainfall runoff precipitate and separate that silt is more.
China Patent Publication No. CN102232133A discloses a kind of device for treating rain water, this equipment comprises housing, this housing is suitable for vertically inserting precipitate and separate device, described precipitate and separate device comprises water inlet and delivery port, a part of sidewall of housing is crooked at least in part, a described part comprises filter, the inside of housing is formed by the first chamber and the second chamber, the first chamber is separated by vertical wall with the second chamber but the passage in the bottom of housing communicates with each other by design, the first chamber is using described filter as its lateral wall, the second chamber comprises and is suitable for the outlet opening that is directly communicated with by discharge pipe with the described delivery port of precipitate and separate device.This treatment facility treatment effect is better, but equipment complex structure needs special maintenance.
China Patent Publication No. CN202410360U discloses a kind of dmp filter purifier, and this device adopts fibre bundle simple structure, has realized gravity backwash, but equipment filters for the processing of early-stage rainwater and need to regular labor cleaning.
The disclosed apparatus structure of China Patent Publication No. CN2249634Y, CN202410274U is simpler, but all must have special backwashing system, and power consumption increases controlling unit when increasing, and is unfavorable for system maintenance.
