Abstract
The utility model discloses a water surface floating cover which comprises a high-density polyethylene film floating cover. A gas collecting device is arranged under the high-density polyethylene film floating cover and is connected with a gas output pipe; and the gas output pipe is connected with the gas collecting device. The high-density polyethylene film floating cover of the water surface floating cover is also provided with an air guide hole and a pressure pipe. The utility model has the advantages that a closed cavity body is formed on a large-area sewage tank through flexible materials; the problems of the damage of attractive peripheral environment, rainwater flowing into the sewage tank, fume diffusion and the like caused by the exposure of the sewage tank are solved; and fume generated by the sewage tank without manual operation can be collected and utilized. The utility model improves the peripheral environment, reduces the processing cost, and has low input cost and good running effect.
Description
Technical field
The utility model relates to a kind of tightness system, and especially a kind of water surface floats and covers.
Background technology
After the high density that refuse landfill produces was oozed drop liquid and delivered to sewage lagoon, liquid level open in the pond gave out foul odour inevitably in the air, promptly polluted air, makes us nauseating again, is repugnant to the eye, and gives " sanitary filling field " antihygienic visual impression; Simultaneously, the rainwater that the open pond face of equalizing tank compiles during rainy season all becomes the principle that sewage also runs counter to the shunting of removing contamination; Sewage is under the certain temperature condition in the sewage lagoon, and microbial proliferation will produce a large amount of biogas (about 60% is methane), be necessary it is collected as the energy, meet " energy-saving and emission-reduction " policy requirements of national requirements, prevents from simultaneously to distribute to pollute.Owing to after adding the cover that floats, make to produce the anaerobism effect in the sewage lagoon, can effectively reduce BOD, the COD concentration of sewage, save sewage work's cost.
Summary of the invention
The purpose of this utility model is to add a cover the deficiency of cost height and poor effect in order to solve the big area sewage lagoon, a kind of flexible cladding system that fluctuates with the water surface is provided, form airtight cavity around this device and the sewage lagoon, the cover that floats fluctuates automatically with the lifting of pool inner water position, simultaneously pool gas is derived in order, need not manual operation.
The technical solution of the utility model is: a kind of water surface floats and covers, this water surface floats to cover and comprises density polyethylene film with high floating head cover, density polyethylene film with high floating head cover has gas extractor, and gas extractor connects gas output tube, and gas output tube connects gas collector.The density polyethylene film floating head cover of the unsteady cover of this water surface also is provided with gas port.The density polyethylene film floating head cover of the unsteady cover of this water surface also is provided with the pressure pressure pipe.
Advantage of the present utility model is: implementing the maximum characteristics in back is exactly that " clear water stream does not advance, and foul smell can utilize, and improves the beautification of the environment, and price is also inexpensive." on the big area sewage lagoon, form an airtight cavity by flexible materials; solved that sewage lagoon openly diminishes that surrounding enviroment are attractive in appearance, rainwater flows into problems such as sewage lagoon and foul smell diffusion, be implemented in no artificial operation and can collect the foul smell of generation in the sewage lagoon and be used.Improve surrounding enviroment, reduce processing cost, input cost is low, and operating performance is good.
Description of drawings
Fig. 1 is the unsteady cover structure synoptic diagram of the utility model water surface.
Embodiment
A kind of water surface floats and covers, and this water surface floats to cover and comprises density polyethylene film with high floating head cover 1, and density polyethylene film with high floating head cover 1 has gas extractor 2, and gas extractor 2 connects gas output tubes 3, and gas output tube 3 connects gas collector.
This water surface floats and covers, promptly adopt the strong density polyethylene film with high of fine uvioresistant (HDPE film) as floating head cover master material, be anchored in the sewage lagoon top all around, float on the cavity that forms a closure on the pool inner water face, density polyethylene film with high floating head cover 1 lower storage reservoir top is provided with gas collector 2 and passes density polyethylene film with high floating head cover 1 in the somewhere all around and centrally disposes.Density polyethylene film with high floating head cover 1 can freely rise and fall with the ups and downs of pool inner water position.
Claims (3)
1, a kind of water surface floats and covers, it is characterized in that: this water surface floats to cover and comprises density polyethylene film with high floating head cover (1), density polyethylene film with high floating head cover (1) has gas extractor (2), and gas extractor (2) connects gas output tube (3), and gas output tube (3) connects gas collector.
