Problems solved by technology

However, decentralized duck farms are mostly located in the surrounding areas of villages, towns, rivers and lakes, and the pollution sources of the farms are scattered. The above-mentioned process only considers the treatment of feces, and the cost is high, and the operation, management and maintenance are more complicated. It is difficult to solve the problem of decentralized duck farms. pollution problem

Embodiment

[0030] The decentralized duck breeding pollution control and resource utilization method is applied to the decentralized duck breeding farm in Baiyangdian District, Anxin County, Baoding City, Hebei Province. The farm is located in Wangjiazhai Village, Anxin Town, Anxin County, Baoding City, Hebei Province. The situation of the farm is like figure 1 As shown, the farm is a typical lake island duck breeding model in Baiyangdian area. The entire lake island covers an area of ​​about 5000 square meters. There is a duck breeding farm with a breeding scale of 1,500. The annual output of duck manure is about 54 tons. Without proper treatment facilities, duck manure is directly washed into the water body, causing serious pollution. There is one household on the island without corresponding sanitation facilities. The island can be divided into housing 1, warehouse 2, duck shed 3, brick area 4, duck water surface activity area 5, duck land surface activity area 6, and reed pond 7.

Abstract

A scattered duck breeding pollution control and recycling method comprises the steps of reducing nitrogen and phosphorus pollutant emission at a source, applying dry duck excrement after composting process to earthworm cultivation, settling duck excrement waste water after methane fermentation, discharging water after settlement to a reed field for purification, and arranging aquatic plants and animals in a duck water surface activity area for digesting and saving the nitrogen and phosphorus in the duck excrement to form an ecologic interception area. The invention can effectively control excrement discharge disorder in the scattered duck breeding, lower contamination to water, realize duck excrement recycling use, optimize breeding environment, and generate economic benefits. The method is simple to implement, and has low cost. strong applicability, and great popularization and demonstration significance.

Description

Technical field [0001] The invention belongs to the field of agricultural environmental engineering, and is a method for pollution control and resource utilization of decentralized duck breeding, which can control the pollution caused by decentralized duck breeding and realize resource utilization. Background technique [0002] The excrement produced by the decentralized duck farm will damage the water quality after entering the surrounding water body. At present, there are many processes for the treatment of livestock and poultry manure, such as biogas fermentation, UASB, ABR, etc. However, most of the decentralized duck farms are located in the surrounding areas of rivers and lakes in villages and towns, and the pollution sources of the farms are scattered. The above process only considers the manure treatment link, and the cost is relatively high, the operation, management and maintenance are more complicated, and it is difficult to solve the decentralized duck farm Pollution...
