AI Technical Summary

Problems solved by technology

First, the oxidation pond system occupies a large area
Second, the oxidation pond system is an uncontrollable system that is very dependent on natural light and heat. In the face of time-varying changes in the quality of aquaculture wastewater, diurnal changes in light and heat, weather changes, climate seasonal and regional changes, etc., adaptive regulation cannot be performed, resulting in The effect of wastewater treatment varies greatly, and in some cases even fails to meet the required effluent quality requirements, causing diseases
Even the various types of oxidation ditches that are widely used in small and medium-sized sewage treatment plants do not require continuous mechanical aeration, which consumes energy

Embodiment 1

[0043] For further details, in the attached figure 2 , image 3 , Figure 4 and Figure 5 In , taking a unit serving 60 breeding boxes as an example, a schematic diagram of the design layout is given according to the size ratio. and figure 1 The system shown is similar to, Figure 2 to Figure 5 Shown is a two-line oxidation ditch system, in which the marked system components and their functions are as follows:

[0044] 1. One of the inner slopes of a rectangular pond. In this example, there are side slopes on all four sides of the pond, where the side slopes at both ends of the rectangle are 1:1, and the side slopes on both sides are 1:2.

[0045] 2. Sewage inlet pipe. Receive and transport the sewage directly discharged from the breeding tank to the pre-high level pool, and connect with the high level pool in the tangential direction in the middle of the high level pool, so as to form a certain swirl in the high level pool to facilitate the settlement of solid particl...

Embodiment 2

[0061] On the premise of maintaining the same flow rate as in the double-line oxidation ditch, in order to reduce the reflow rate and save electric energy, the oxidation ditch can be arranged as a single line. Figure 6 A schematic diagram of the plane layout of a single-line oxidation ditch is given, the design conditions and the components of the system marked in the figure and their functions and Figure 2 to Figure 5 same. The difference between single-line and double-line is that the double-line system adds two peripheral shallow water delivery channels (as shown in Figure 17), and the range of sedimentation tanks is adjusted accordingly.

[0062] The system layouts of the two examples given in the accompanying drawings in this specification are only demonstrations for regular rectangular ponds or pools. In practical applications, if you encounter ponds with different geometric shapes, you can make corresponding reasonable arrangements according to local conditions. If t...

Abstract

The invention discloses an integrated slope type oxidation ditch sewage treatment system which is used for treating and recycling aquatic ectopic aquaculture wastewater. The invention aims to solve the problems of incapability of regulating and controlling, unstable effluent quality, large occupied area and the like when three-stage pond treatment is adopted for aquatic ectopic culture wastewaterat present. The system adapts to the characteristics of a soil slope pond, planar functional isolation is carried out on an original first-stage pond according to the water depth, and the slope plug flow oxidation ditch sewage treatment system integrating hydrolytic acidification, nitrification and denitrification and solid-liquid separation is formed. The oxidation ditch is arranged along the inclined direction of the slope, so that water flow alternately passes through a shallow water area and a deep water area to realize alternate reoxygenation and oxygen consumption, and dependence on mechanical oxygen supply is avoided. In addition, a higher-place pond is arranged for feeding water according to different qualities, and reflux devices are arranged for the acidification ditch and the oxidation ditch respectively. Therefore, the system can be regulated and controlled in operation, can adapt to changes of water outlet requirements, inflow, weather, seasons, weather and the like, greatly improves the treatment efficiency, and remarkably saves land. The system can also be used for village and town domestic sewage treatment in vast rural areas.

Description

technical field [0001] The invention relates to a complete set of technology for the treatment and reuse of aquatic ectopic aquaculture wastewater, especially a new type of oxidation ditch Background technique [0002] Aquaculture is an important agricultural field in my country, but its large occupation and pollution of water resources make the transformation of traditional farming mode increasingly imminent. The introduction and application of industrial farming technology in my country has gone through 30 to 40 years of twists and turns. In addition to several other factors, how to economically and effectively treat wastewater for reuse has always been a bottleneck. The treatment and reuse of aquaculture wastewater not only requires water purification, but also a good micro-ecology to facilitate the growth of fish and shrimp and disease control. The latter usually requires outdoor natural processes to achieve. Over the years, aquaculture wastewater has focused on the dev...
