Resourceful treatment system of pond sediments

Abstract

The invention relates to a treatment system of water for aquaculture, in particular to a resourceful treatment system of pond sediments. The system is characterized in that a cement pile (8) is embedded at the bottom in the center of a pond (2); a central support pillar (7) is fixed on the cement pile; at the upper end of the central support pillar, at least three ropes (3) are pulled and fixed on cement columns (1) embedded on the periphery of the pond; one end of a guide rod (12) horizontally arranged in the pond water is sleeved on the central support pillar (7) by a sliding sleeve (4) andthe other end of the guide rod is connected with a sediment agitator (13); driven by a radial movement mechanism, the sediment agitator (13) radially moves toward or away from the central support pillar (7) along with or along the guide rod (12) while moving along the circumferential direction of the bottom surface of the pond (2). The resourceful treatment system has the following advantages: the organic floccule on the surface layer of the sediments in the whole pond is lifted through mechanical moving adsorption and the digestion capability and cenobium energy of the organic matters are improved by utilizing the dissolved oxygen and alkalinity on the photosynthesis layer to promote organic matter decomposition and phosphorus release and reduce accumulation of the organic matters, thus reducing culture pollution and improving the productivity and culture efficiency of the water body in the pond.

Description

[0001] technical field [0002] The invention relates to a water quality treatment system for aquaculture, in particular to a treatment system for resourceful treatment of pond bottom mud. [0003] Background technique [0004] Pond farming is the main form of aquaculture in my country. According to the data in "China Fishery Yearbook 2010", in 2009, my country had 4.164 million hectares of pond aquaculture area, and the aquaculture output was more than 18.52 million tons, accounting for more than 51.1% of the total aquaculture output. Studies have found that, except for 20%-30% of the nutrients such as nitrogen and phosphorus input in the breeding process are absorbed and utilized by the breeding organisms, the rest all enter the breeding environment, and the eutrophic substances in the breeding water are discharged to the outside with the discharge water. In and out of the environment, about 60-70% is deposited in the bottom mud of the pond, and the drugs and chemicals i...
