Description
Technical Field
The utility model belongs to the field of water treatment, relates to a rainwater treatment system, and particularly relates to a fluorine chemical enterprise rainwater and sewage diversion and drainage system.
Background
At present, the environmental protection of chemical industrial parks is more and more important, and the discharge of sewage, rainwater and the like needs to meet certain environmental evaluation standards, including CODcr, water quantity, pH, characteristic pollutants and other detection indexes. In order to meet the strict environmental evaluation standard, a corresponding drainage scheme needs to be designed and constructed in the chemical industry park, and the scientific, reasonable and effective drainage scheme is particularly important.
At present, the following problems mainly exist in the drainage design of a chemical industrial park: the manual switching device for initial polluted rainwater and later clean rainwater mostly adopts a split-flow switching form of a gate valve, a bell jar or an overflow weir. The manual control method has many defects, for example, the gate valve is used for opening and closing, the purposes of shunting and switching are difficult to achieve due to time and labor consumption, particularly, the valve is required to be opened at the initial stage of rain, and is closed after 10-15 min, so that the actual situation is difficult to achieve, and as a result, all initial polluted rainwater and later clean rainwater are discharged into a sewage treatment plant, and the load of the sewage treatment plant is increased. Or the initial polluted rainwater and the later clean rainwater are all discharged into a rainwater pipeline, so that the environment is seriously polluted. Moreover, the gate valve can not be opened after a long time due to pollution and the like. The overflow weir type can solve the problem of shunting of initial polluted rainwater, but rainwater always flows to a sewage treatment plant from the beginning of rainfall to the end of rainfall, so that the pipe diameter of a plant sewage pipeline is increased, the sewage treatment plant is impacted, the load of the sewage treatment plant is artificially increased, and the overflow weir type is not economical and is unfavorable for treatment. In addition, the manual control is adopted, so that the flexibility is too high, which is related to the factory system and the responsibility of workers, and the implementation is difficult, and the final shape is similar to the nominal shape. And the rainwater collection time in the early stage of heavy rain and light rain is different, and manual control is difficult to control. In addition, if there is another rainfall within a period of time (24 hours or more) after the beginning of the rainfall, the latter rainfall should not collect the initial rainwater any more because the interval time between the former and latter rainings is too short and the ground has no more pollutants.
In addition, the centralized collection is that 1 initial rainwater collecting pool is arranged in the whole plant, and the centralized collection is suitable for the condition that the area of the plant area is small or the pollution areas such as the device area and the storage tank area are concentrated. The rainwater collecting device has the advantages that the initial rainwater collecting pipeline is long, buried underground is deep, the investment of pipe network construction is large, the position of the collecting pool is limited, and the initial rainwater runoff time of different areas is different, so that the initial rainwater of the far-end polluted area does not reach the collecting pool, and is filled with clean rainwater in the later period of the near-end polluted area, and the shunting effect is not achieved.
The fluorine chemical industry enterprises are more important in water drainage design due to the particularity of fluorine-containing products, most of the water drainage of the fluorine chemical industry enterprises at present have the problems of high treatment cost, high operation and maintenance cost and difficulty in reaching the high environmental standard even the treatment result, and particularly for the treatment of rainwater, the water drainage design which can meet the environmental requirement and has relatively low operation cost is urgently needed.
