Water body decontamination system and application thereof

Abstract

The invention relates to a water body decontamination system and an application thereof, wherein the system can improve dirt removing effect, and can meet energy saving, emission reduction and consumption reduction requirements; the system comprises a gas generator arranged in a pond and used for continuously forming gas, and a water lift pipe arranged above the gas generator; the water body decontamination system is applied in pond decontamination. Compared with the prior art, the advantages are that the system can use a sewage pond to settle and recoil solid dirt such as residual feeds and night soils formed in the culture process, or can use a filter net or an air floatation to gather the dirt and discharge same; less dirt-pulling is combined to remove heavy solid objects such as largehard particles and residual feeds, thus realizing excellent decontamination effect, and removing more than 90% of culture night soil; the system uses very limited water consumption and energy consumption in decontamination, thus providing excellent energy saving and emission reduction effects; specially, the surface treatment is done for bottom night soil via the air floatation, thus changing theconventional decontamination modes.

Description

technical field [0001] The invention relates to the fields of breeding facilities and equipment and breeding techniques, in particular to a water body cleaning system and its application. Background technique [0002] In the process of aquaculture, a large amount of solid waste such as feces and residual bait often accumulates at the bottom of the pond, which not only affects the aquaculture water environment, but also directly affects the feeding grounds and living habitats of farmed animals, especially shrimps, etc. Benthic cultured animals. If the bottom of the pool is not cleaned up in time, it is easy to deteriorate, produce hypoxia, and breed harmful microorganisms, etc., resulting in excessively high levels of harmful factors such as ammonia nitrogen, nitrous nitrogen, and hydrogen sulfide in the water, especially the bottom water, or a large number of harmful organisms Breeding, causing emergencies and disease in aquaculture animals, especially in seasons with chang...

AI Technical Summary

Problems solved by technology

For example, in high-density shrimp ponds, cleaning the bottom of the pond by means of decontamination and manual cleaning has achieved certain results, but this operation method has obvious disadvantages: First, the operation must be careful, which is easy to interfere with the breeding animals and increase the cost of breeding. threat of biological injury

Second, large-scale production operations are labor-intensive and time-consuming, which not only increases labor intensity, but also increases labor costs, especially in the current period of high labor costs

The third is that it is not conducive to disease prevention management, that is, it is easy to introduce pathogenic organisms, especially susceptible farmed animals such as prawns, resulting in frequent occurrence of diseases and difficult control, or frequent use of drugs after the onset, resulting in problems such as excessive drug residues and product quality and safety. , or even extinct, extinct harvest

The fourth is that the one-time water change when cleaning the sewage at the bottom of the pool is too large, resulting in rapid environmental changes, causing emergencies and even diseases of farmed animals, which also affects the surrounding environmental ecology, and even causes problems such as non-point source pollution in the breeding area.

Fifth, due to the large water consumption, pumping requires energy, or it is necessary to dig more manholes, or build more filter pools, or storage pools, or treatment pools, or heating systems, etc., resulting in waste of facilities, equipment, and energy , which is also contrary to my country's current national policy of advocating energy conservation, emission reduction and circular economy
