Problems solved by technology

[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, to provide a straw-biochar-bio-integrated artificial wetland method for treating aquaculture wastewater, to organically combine environmental management with aquaculture and planting, and to fundamentally solve the problem of aquaculture. The environmental pollution of waste, while achieving the standard discharge of aquaculture wastewater and improving the local ecological environment, significantly reduces the pollution control cost of the enterprise, further extends the industrial chain of the enterprise, and uses aquaculture waste to produce high-quality organic fertilizer and high-quality green fodder , to improve the economic benefits of the farming industry

Example Embodiment

[0018] In the following, the technical solutions of the present invention will be further described in detail through embodiments and in conjunction with the drawings.

[0019] Such as Figure 1 ~ Figure 7 As shown, the method for treating aquaculture wastewater in a straw-biochar-bio-integrated constructed wetland includes sequentially passing the aquaculture wastewater through an anaerobic fermentation tank 1, three substrate tanks 2, and four wetland tanks 3. The anaerobic fermentation tank Between 1 and the first substrate pool 2, between two adjacent substrate pools 2, and between the third substrate pool 2 and the first wetland pool 3, a substrate groove 4 is provided. The substrate groove 4 and the substrate The cross section of the pool 2 is an inverted trapezoid. The water inlet and water outlet of each substrate pool 2 are arranged on opposite sides and far away from each other.

[0020] Such as figure 2 As shown, the bottom of the substrate trench 4 is 100-250cm wide, th

Abstract

The invention discloses a method for treating artificial wetland breeding wastewater by integration of straw, biochar and organism. According to the method, breeding wastewater passes an anaerobic fermentation tank, three substrate tanks and four wetland tanks in sequence; a substrate channel is arranged between the anaerobic fermentation tank and the first substrate tank, between two adjacent substrate tanks, as well as between the third substrate tank and the first wetland tank; straw is laid in the substrate channels and the substrate tanks; wild plants are added onto the straw; a water blocking drop water dam is arranged at the water outlet of each substrate tank; the wetland tanks are surrounded by ridges; two adjacent wetland tanks are separated through one ridge; overflow openings of which the cross sections are in the shape of an inverted trapezoid are formed in the upper end surfaces of two ridges of each wetland tank; myriophyllum verticillatum is added into each wetland tank; a biochar layer is arranged in front of the overflow opening, near discharged water, of the last wetland tank. According to the method for treating artificial wetland breeding wastewater by integration of straw, biochar and organism, the water quality of the end discharged water is greatly superior to the water pollutant discharge standard of the national breeding industry.
