The invention has the advantages that oyster cultivation waste can be recycled, sea mud can be used as bait of sea cucumber after being filtered and dried, and can also be used as organic fertilizer of fruits and vegetables, crushed oyster shells can be used as soil conditioner and additive of livestock and poultry feed, and tail water after disinfection or cleaning is recycled after precipitation treatment, and is pollution-free and emission-free.
Drawings
The invention is further illustrated with reference to the following figures and examples.
FIG. 1 is a schematic view of a drying plant for recycling oyster farming waste.
In the figure, 1 is a roof, 2 is a ventilation opening, 3 is a house wall, 4 is a drying table board, and 5 is a solar hot water pipe.
Detailed Description
The invention can be realized by the following steps:
1. the waste produced after cleaning oysters harvested from sea comprises oyster shells and sea mud attached to the oyster shells, the waste is concentrated and placed in a disinfection tank, the disinfection tank can be higher than the ground or lower than the ground, a water pipe is arranged on the tank wall or the top of the disinfection tank, 1-10 spray heads are installed on the water pipe, and the water pipe is connected with ozone water solution (4-60 g/m) with high ozone concentration3) Spraying for 5-30 min to kill bacteria and viruses in waste and oxidize and decompose harmful substances in the waste, so as to achieve the effects of sterilization, disinfection and deodorization.
2. The sterilized waste is conveyed to a cleaning machine through a conveyor belt to be cleaned, the cleaning water can be seawater or fresh water, and ozone water with high ozone concentration can be added into the cleaning water to play a role in further sterilizing and disinfecting. The cleaned waste is separated into two parts at the outlet of the cleaning machine, the upper layer is clean oyster shells, and the lower layer is clean sea mud.
3. And (3) treating the cleaned sea mud: clean sea mud that comes out from the cleaning machine flows in the sea mud collecting pit along with water, and the collecting pit passes through the pipe connection sedimentation tank, installs 40 ~ 80 mesh sieves under sedimentation tank upper portion pipeline mouth, and sea mud passes through the pipeline and flows in the sedimentation tank, filters through fine screen, after the sediment, transports the stoving workshop with the loading of sewage suction pump extraction and dries, perhaps with the pipeline lug connection of sewage suction pump to stoving workshop, directly carries the stoving workshop with sea mud from the sedimentation tank.
Drying workshop structure: the drying workshop is internally provided with a black drying table top 4, the drying table top 4 is of a cement mortar structure, the thickness of the drying table top 4 is 5-30 cm, the upper surface of the drying table top is coated with black, a solar hot water pipe 5 is arranged below the drying table top 4, the solar hot water pipe 5 is spaced by 5-20 cm, the upper half part of a house wall 3 around the drying workshop is provided with a ventilation opening 2, ventilation and exhaust equipment is installed, and a roof 1 of the drying workshop is made of light-transmitting materials such as light-transmitting color steel tiles.
The application comprises the following steps: the drying table board 4 is heated by the solar hot water pipe 5, the temperature of the drying table board 4 can reach 20-80 ℃, the black drying table board 4 also has the functions of heat absorption and light absorption, the sea mud after cleaning, filtering and precipitating is laid on the drying table board 4 for drying treatment, the thickness of the sea mud is 2-15 cm, the ventilation of a workshop is good, the roof 1 is light-permeable and can shield dust and rain, the drying of the sea mud is facilitated, the sea mud can be dried generally after 2-12 hours, and the dried sea mud can be collected into bags to be used as bait for sea cucumbers.
4. And (3) processing the cleaned oyster shells:
the cleaned clean oyster shells are directly bagged and transported to a drying workshop for drying, or are dried outdoors and air-dried, crushed by a crusher, sieved by a fine sieve and used for soil conditioners or feed additives.
5. The tail water after disinfection or cleaning flows into a sedimentation tank, and can be reused for the disinfection treatment in the step 1 after sedimentation.
Sea mud attached to oyster shells is subjected to ozone disinfection treatment, so that bacteria in the sea mud can be killed, a deodorization effect can be achieved, the sea mud can be used as bait of sea cucumbers after being filtered and dried, the crushed oyster shells can be used as an additive of a soil conditioner and livestock and poultry feed, and the larger oyster shells are used as raw materials for reprocessing the oyster shells after being cleaned and aired.
