Description

Zero release integration breeding tail water treatment device based on thing networking

Technical Field

The invention belongs to the technical field of water treatment, and particularly relates to a zero-emission integrated cultivation tail water treatment device based on the Internet of things.

Background

At present, the phenomena of blue bath outbreak of large lakes in China, more and more common black and odorous riverways in cities and towns and the like reflect that the self-cleaning capacity of water bodies in public water areas is not enough to digest pollution caused by substandard water bodies discharged by agriculture or industrial production. A considerable part of the pollution in agricultural production is caused by the untreated discharge of aquaculture tail water.

The aquaculture tail water is water which is generated by aquaculture (including aquaculture ponds, factory workshops and the like) activities and is discharged into external public water areas and is not used for aquaculture. In the traditional aquaculture industry, the culture tail water is not treated generally and is directly discharged into rivers or lakes in a direct discharge mode. However, with the continuous increase of the current culture density and the continuous improvement of the protein content in the feed, the content of nitrogen and phosphorus in the culture tail water is also greatly improved. If the culture tail water is directly discharged without being treated, the water quality of public water areas is greatly influenced, and the environment is greatly polluted.

Therefore, the tail water of aquaculture industry is treated and discharged after reaching standards, and the latest discharge standard of pond culture tail water places is definitely specified. At present, a three-channel four-dam plus plant degradation method or a wetland method is generally adopted for treating the aquaculture tail water, and the two methods cannot provide a large amount of oxygen and a deoxidation environment in the links of oxygen consumption and anaerobism, so that the completeness of biochemical reaction is not facilitated, the treatment efficiency is low, the speed is slow, the treatment result is not controllable, and the requirement of rapid degradation of nitrogen and phosphorus in aquaculture which seriously exceeds the standard cannot be met.

In addition, some culture tail water treatment equipment is already available on the market, but most of the existing culture tail water treatment equipment has some problems:

1. before the biochemical treatment link, the solid pollutants in the water body cannot be separated, so that the effect of subsequent biochemical treatment is influenced;

2. in the anoxic biochemical treatment link, the required anoxic or anaerobic environment cannot be created;

3. in the aerobic biochemical treatment process, a large amount of oxygen required by the aerobic biochemical treatment process cannot be provided, so that the reaction is quicker and more complete.

4. The whole device occupies a large area, and the device is difficult to move after being installed.

5. Although the treated effluent of the culture tail water really meets the requirement of reaching the discharge standard, the sludge degraded after treatment cannot be further treated, and if the sludge is directly discharged, the environment is still polluted.

6. The whole set of device only has a local control function and cannot realize remote control and online monitoring.
