Embodiment 1

[0023] The purpose of the present invention is to provide a sustainable development management method for aquaculture sewage treatment pools, strictly regulate the construction and management of aquaculture sewage treatment pools, improve the water quality of aquaculture sewage, and improve the recycling of nitrogen and phosphorus resources. The steps are:

[0024] (1) Construction of aquaculture sewage treatment ponds centered on chrysoprase, including secondary wetland biomass purification pools, quaternary ecological wetlands chrysanthemum ecological wetlands, and circular aquaculture paddy fields. After solid-liquid separation, the waste pollutants from farming enter the secondary wetland biomass purification ponds with rice straw added, and then enter the fourth-level ecological wetlands with green foxtail algae planted respectively. After being treated in the second-level wetland biomass purification pond and the fourth-level ecological wetland green foxtail ecological we...

Abstract

The invention discloses a sustainable development management method for a breeding sewage treatment tank. The method comprises the following steps: (1) building a breeding sewage treatment tank with Myriophyllum elatinoides as a core, wherein the breeding sewage treatment tank comprises a two-stage biomass purification tank, a four-stage Myriophyllum elatinoides ecological wetland and a circulating breeding paddy field, and enabling tail water treated by the two-stage biomass purification tank and the four-stage Myriophyllum elatinoides ecological wetland to enter the circulating breeding paddy field for duck breeding in the paddy field; (2) updating straws in each stage of the biomass purification tank every three months; (3) putting straws into each stage of the Myriophyllum elatinoidesecological wetland, wherein 0.5-1kg/m<3> of the straws are put into each cubic meter of the ecological wetland; (4) harvesting Myriophyllum elatinoides in each stage of the Myriophyllum elatinoides ecological wetland in an interlaced manner once every three weeks; and (5) planting rice in the circulating breeding paddy field, and breeding ducks under the rice. The method is simple in process, convenient to operate and capable of remarkably repairing the pollution of an eutrophic water body, fundamentally improving water quality, improving the self-purification capacity of the water body and promoting recycling of elements.

Description

technical field [0001] The invention relates to the field of aquaculture sewage treatment, and more specifically relates to a sustainable development management method of an aquaculture sewage treatment pool, which is suitable for the aquaculture industry in which green foxtail algae is used to treat aquaculture sewage. Background technique [0002] In recent years, with the rapid development of my country's livestock and poultry breeding industry, the discharge of major pollutants such as chemical oxygen demand and ammonia nitrogen is increasing. However, due to the relatively weak foundation of agricultural source emission reduction management, insufficient capital investment, the comprehensive utilization of livestock and poultry waste and the construction of treatment projects are seriously lagging behind, causing serious environmental pollution problems and putting great pressure on environmental protection. At present, in response to these current situations, my countr...
