Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] Referring to Fig. 1, the water body purification method of the present invention can pass through the sewage collection pipe device 2, the central sewage discharge pipe 3, the water pump 4, the water delivery pipe 5, the water distributing device 6, the shallow water pipe device 2 that are arranged at the central bottom of the aquaculture pond 1 of the gentle pot bottom type. The natural light circulation water purification system composed of layer sedimentation tank 7 and actinic slope 8 is realized. The sewage collection pipe device 2 is composed of 8 perforated sewage collection hard plastic pipes and 1 sewage discharge pipe, which is used to collect the residue at the bottom of the pool and the bottom layer of inferior quality. The central blowdown pipe 3 is a socket hard plastic pipe, which can make waste water and residues with higher organic loa...

Abstract

The present invention discloses water purifying method for cultivation pond. The method is one water circulating process including pumping cultivation waste water from the bottom of pond center to one water trough; separating suspended organic matter from water in the water trough; natural photochemically catalytic oxidation of water; and returning the treated water to the pond. The method of the present invention can eliminate water pollution for aquatic cultivation in relatively low cost, improve the physical, chemical and biological conditions of cultivation water, and raise the water environment stability of cultivation water, and is suitable for pond cultivation with both sea water and fresh water.

Description

technical field [0001] The invention relates to a water body purification method of a culture pond, in particular to a circulating water body purification method of a culture pond. Background technique [0002] In view of the adverse effects of nitrogen, phosphorus, organic suspended solids and harmful microorganisms in the large-scale aquaculture water and drainage on the animals and the water environment, the existing solutions are mainly to change water, add chemical oxidants or Microecological agents, industrial water purification, ecosystem compensation and other methods. The measure of water change is to directly discharge part of the aquaculture wastewater regularly and then add some fresh clean water to achieve the purpose of improving the physical, chemical and biological conditions of the water body. The biggest downside to changing the water is at the expense of the environment. The biggest disadvantage of regular dosing of chemical oxidizing agents is that it d...
