Description
Technical Field
The invention relates to the field of environmental protection equipment, in particular to a rain and sewage separator and a rain and sewage separation method using the same.
Background
At present, in order to improve environmental protection and strengthen construction of rural life infrastructure, rural domestic sewage treatment projects are gradually developed in China, because rural houses are scattered in layout, a dispersed collecting and dispersing treatment mode is generally adopted, and the main problems encountered in the process of collecting sewage are that most of rural house sewage is discharged from the front and back of a house and from the surface, rainwater and sewage in courtyard are simultaneously discharged in a drainage ditch, and rainwater and sewage are mixed. Most collection scheme of present design all is that collecting pit and rural institute escape canal dock, and rainy day rainwater sneakes into sewage conduit, leads to sewage equipment overflow, washes away the fungus mud in the equipment simultaneously, directly leads to sewage treatment not up to standard, destroys ecological environment.
Rural house construction lacks unified planning, and the distribution of rain and sewage is difficult to realize, has large-scale distribution of rain and sewage device on the market, but only is applicable to the large-scale rain and sewage pipe network in city, and the indiscriminate emission to rural domestic sewage still does not have professional distribution of rain and sewage device at present. The early rural domestic sewage collecting tank is directly butted with the drainage ditch, does not have the rain and sewage diversion function, and pipelines and equipment overflow everywhere in rainy days. Set up sewage collecting tank in the institute for solving the reposition of redundant personnel of rain and sewage proposes, and the pond is higher than ground, and only the pond mouth can receive the rainwater, and other rainwater can not get into the pipeline, plays certain reposition of redundant personnel of rain and sewage effect, but the user need be with domestic sewage water pouring into the effluent water sump, makes sewage discharge become loaded down with trivial details, be not convenient for carry out, and the effluent water sump blocks up easily simultaneously, clears up inconveniently. The sewage collecting tank is improved, a water blocking ridge is arranged at the bottom of the tank, the front end of the water blocking ridge is connected with a sewage pipeline, and the rear end of the water blocking ridge is provided with an overflow port. Only when sewage enters, the sewage volume is little can't cross the water blocking bank, directly gets into the sewage pipeline through the sewage mouth, and the rainwater water yield increase when mixing, crosses and arranges away through the overflow hole behind the water blocking bank, and this scheme has only solved the rainwater and has sneaked into the problem of sewage pipeline volume, but in the rainwater overflow, the rainwater also is in the inflow sewage pipeline that does not stop, does not solve the problem of rain and sewage mixed flow. The position that gets into sewage treatment device at sewage pipe increases the overflow well, and the rainwater is sneaked into when the sewage pipe water yield increases and is directly discharged into river course or low-lying district through the overflow, and this scheme has reduced the sewage of equipment and is excessive, can not solve the dirty mixed flow problem of rain. The investment of all the three solutions is increased, but the rain and sewage diversion cannot be effectively realized.

a. the rain and sewage separator is in an automatic state,
1. in the daily life of the user, the user can easily see the situation,
1.1 the sewage flows out of the drainage ditch and enters the rain and sewage separator along the water inlet, and the position of the water inlet sewage channel is lower than that of the inlet rain water
When the sewage is discharged and the sewage is not collected in the gravity tank, the first return spring enables the sewage baffle to return to a closed state;
2. when it is raining, the rain-proof device can be used,
2.1 the rainwater volume exceeds the sewage passageway maximum flow 0.5L/s of intaking, the rainwater overflows into the rainwater passageway, the rainwater collects at the water inlet end and forms the side pressure and pushes away the rainwater baffle, rainwater baffle width is 2 ~ 3 times sewage baffle width, rainwater baffle thrust is 2 ~ 3 times sewage baffle thrust, rainwater baffle opening force passes to in sewage baffle through biography power spring, thereby close the sewage baffle, the rainwater volume is big more, the rainwater collects and forms the side pressure big more, it is also big that thrust is received to the rainwater baffle, thrust through passing power spring transmission is also big more, the sewage baffle is closed and is just tighter, the rainwater flows through the rainwater baffle of opening, directly get rid of along the rainwater passageway of going out, or flow in the rainwater ditch and discharge.
b. The rain and sewage separator is in a manual state
1. In the daily life of the user, the user can easily see the situation,
1.1 inserting a rainwater baffle into a rainwater baffle rail, extracting a sewage baffle from the sewage baffle rail, enabling sewage flowing out of a drainage ditch to enter a rainwater and sewage separator along a water inlet, enabling a water inlet sewage channel position to be lower than a water inlet rainwater channel position, enabling the sewage to flow into a gravity pool along a sewage diversion groove, and enabling the sewage to flow out of the gravity pool and enter a sewage pipeline along a water outlet sewage channel to be discharged to sewage treatment equipment;
2. when it is raining, the rain-proof device can be used,
2.1 take the rainwater baffle out, insert the sewage baffle, the rainwater flows out from the escape canal, get into the rain and sewage separator, the sewage passageway position of intaking is less than the rainwater passageway position of intaking, the rainwater enters into the gravity pond along the sewage guiding gutter, the sewage baffle inserts and plays the effect that stops the rainwater and get into out water sewage passageway on the sewage baffle track, the rainwater collects at the sewage passageway of intaking, exceed the sewage passageway maximum flow 0.5L/s of intaking when the rainwater volume, the rainwater baffle has been taken out, the rainwater is gushed into and is got into the direct inflow rainwater passageway of rainwater, directly discharge along the rainwater passageway of effluenting, perhaps flow into the rainwater ditch and discharge.
