Abstract
The invention discloses a shrimp larva raising sewage treatment system, which includes a culture sewage pool, an aeration pool and a sedimentation pool. The discharge outlet of the culture sewage pool is communicated with a corresponding inlet of the aeration pool through a discharge pipeline. The discharge outlet of the aeration pool is connected to the sedimentation pool through a pipeline. The activated sludge discharge outlet of the sedimentation pool is communicated with a corresponding inlet of the aeration pool through a reflux pipeline. The system disclosed in the invention has the advantages of simple structure and no pollution, and can realize high efficiency purification treatment on shrimp larva raising pool sewage.
Description
Technical field
The present invention relates to a seed shrimp seedling Sewage treatment systems.
Background technology
The sewage that discharge in shrimp seedling pond is organic and bacteria content is all higher, if these sewage are directly entered the sea area, pollutes on the one hand the seawater in peripheral sea area, reduces the seawer quality that extracts, and increases the mutual chance that infects of disease; Sewage directly discharges on the other hand, does not reach discharging standards.
Summary of the invention
The purpose of this invention is to provide a seed shrimp seedling Sewage treatment systems, it can realize that prawn seedling pond sewage carries out effective purifying treatment.
The present invention is achieved in that
One seed shrimp seedling Sewage treatment systems comprises: aquaculture wastewater pond, aeration tank and settling tank; The discharge outlet in described aquaculture wastewater pond is by corresponding the enter mouthful UNICOM of discharge tube with described aeration tank, and the discharge outlet of described aeration tank connects described settling tank by pipeline; The active sludge relief outlet of described settling tank passes through reflux line UNICOM with the corresponding mouth that enters of described aeration tank.
Described settling tank top is provided with the primary water overflow port.
Be provided with aerating apparatus in the described aeration tank.
Be equipped with stopping valve on the described pipeline.
The present invention is simple in structure, and is pollution-free, can realize that the high-efficient purification of prawn seedling pond sewage is processed.
Description of drawings
Fig. 1 is the structural representation of the shrimp seedling Sewage treatment systems that provides of the embodiment of the invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail below.
Referring to Fig. 1, a seed shrimp seedling Sewage treatment systems comprises: aquaculture wastewater pond 1, aeration tank 2 and settling tank 3; The discharge outlet in described aquaculture wastewater pond 1 is by corresponding the enter mouthful UNICOM of discharge tube with described aeration tank 2, and the discharge outlet of described aeration tank 2 connects described settling tank 3 by pipeline; The active sludge relief outlet of described settling tank 3 passes through reflux line UNICOM with the corresponding mouth that enters of described aeration tank 2.
Wherein, described settling tank top is provided with the primary water overflow port.
Be provided with aerating apparatus in the described aeration tank.
Be equipped with stopping valve on the described pipeline.
In system when operation, enter the aeration tank simultaneously with the sewage to be processed deposited in the cultivation sewage lagoon and the active sludge of backflow, makes it become mixed solution; Then carry out aeration by aerating apparatus to the aeration tank injecting compressed air, the described sewage that enters is fully mixed with active sludge contact, supply with simultaneously the enough dissolved oxygens of described mixed solution; Under aerobic state, organism in described sewage decomposed by the microbial population in the described active sludge and obtain stable after, described mixed solution is entered settling tank to be precipitated, until active sludge with after primary water separates, the described active sludge of part is back to described aeration tank by the active sludge relief outlet through reflux line mixes again row processing with the sewage that newly enters, described primary water then discharges after the overflow of primary water overflow port is by sterilization and gets final product.Active sludge can constantly increase in treating processes, and unnecessary mud need to be transported processing by the sludge pump suction from system.
The present invention is simple in structure, and is pollution-free, can realize that the high-efficient purification of prawn seedling pond sewage is processed.
More than disclosed be specific embodiments of the invention only, but the present invention is not limited thereto, for the person of ordinary skill of the art, under the prerequisite that does not break away from the principle of the invention, the distortion of making should be considered as belonging to protection scope of the present invention.
Claims (4)
1. a seed shrimp seedling Sewage treatment systems is characterized in that, comprising: aquaculture wastewater pond, aeration tank and settling tank; The discharge outlet in described aquaculture wastewater pond is by corresponding the enter mouthful UNICOM of discharge tube with described aeration tank, and the discharge outlet of described aeration tank connects described settling tank by pipeline; The active sludge relief outlet of described settling tank passes through reflux line UNICOM with the corresponding mouth that enters of described aeration tank.
