Embodiment Construction
[0030] Examples see figure 1 , figure 2 As shown, this liquid or semi-solid waste closure system includes a pit 1 for containing liquid or semi-solid waste, and the surface of the liquid or semi-solid waste 2 in the pit is covered with a floating cover anti-seepage membrane 3, The anti-seepage film 3 of the floating cover is a plastic film welded as a whole. An anchoring ditch 4 is provided around the pit pool, and the edge of the anti-seepage film of the floating cover is fixedly embedded in the anchoring ditch. A circle of gas collecting pipes 8 is arranged under the anti-seepage film of the floating cover and around the wall of the pit pool. Gathering holes are distributed, and the gas collecting pipe 8 is connected with the upwardly extending exhaust pipe 10 by the three-way pipe 9. The diameter of the top nozzle of the exhaust pipe 10 becomes smaller gradually, and a fastening ring flange 11 is connected on the top surface. A floating raft 5 is arranged between the top...

The invention discloses a liquid or semisolid waste closing system and a method thereof. The system comprises a puddle for containing liquid or semisolid waste; a layer of floating head permeability-preventing film is covered on the surface of the liquid or semisolid waste in the puddle; an anchoraging channel is arranged around the puddle; the edge of the floating head permeability-preventing film is fixedly embedded into the anchoraging channel; a cycle of gas collecting pipes are arranged around the wall of the puddle and below the floating head permeability-preventing film; gas collecting holes are distributed on the gas collecting pipes which is connected with upwards extending exhaust pipes through a tee pipe; a buoyant raft is arranged between the upper side of the liquid or semisolid waste and the floating head permeability-preventing film; and a ballast weight is pressed on the floating head permeability-preventing film. The invention solves the problem of closing the liquid or semisolid waste, can prevent gases from freely emitting, rain and waste from mixing and incidents from happening and is suitable for places such as mud and sewage reservoirs, Enteromorpha prolifera disposal sites, and the like where a great amount of harmful gases are easy to produce and incidents are easy to happen.
Description
technical field [0001] The invention relates to a waste treatment technology, in particular to a treatment device and method for liquid or semi-solid waste. Background technique [0002] Enteromorpha is a cotton-like seaweed with strong adaptability and reproductive ability to the environment. It has gathered in large numbers in my country's sea areas in recent years. The occurrence of Enteromorpha affects the progress of marine sports competitions and creates a burden on urban environmental sanitation. Because Enteromorpha contains a lot of water, it is easy to produce harmful gas when it is processed, and it is easy to mix rain and sewage in thunderstorm weather to produce liquid or semi-solid waste. [0003] At present, it is known that the country has the "Technical Regulations for Closure of Domestic Garbage Sanitary Landfill Sites". This technical regulation is suitable for the closure of domestic waste landfills, and it is not applicable to the closure of liquid or m...
