Circulating system with integrated ecological cultivation, planting and liquid manure treatment

Abstract

The invention discloses a circulating system with integrated ecological cultivation, planting and liquid manure treatment; fecal wastewater from a cultivation house in the system is discharged into a fecal wastewater collection tank and is then pumped into a solid-liquid separation station by a sewage pump, solid-liquid separation is carried out through a stainless steel mesh and gravels, solid extracted out via a solid-liquid separator is mixed with domestic waste to obtain organic fertilizer, the domestic waste is crushed with a crusher before the mixing, the separated liquid is charged into an underground permeation pipeline in a crop planting area and / or an economic forest planting area, the liquid is absorbed and purified by crops, the purified liquid is charged into an earthworm cultivation pond and permeates into a cultivation water tank, the water in the cultivation water tank is used for washing the house so that water resources are recycled, and biogas in the solid-liquid separation station is collected and stored for use. The circulating system of the invention has no emission of stinking gas, and allows resources to be recycled to achieve both pollution solving and economic income so that efficient cycle of economic development is finally achieved.

Description

technical field [0001] The invention relates to a method for treating feces and wastewater in aquaculture, and more specifically, the invention relates to a circulation system integrating ecological breeding, planting and manure treatment. Background technique [0002] The large-scale farming model has become a trend to replace the traditional family farming model that has lasted for thousands of years. This change has brought high returns and some problems to the countryside. The most representative of these is the livestock and poultry manure that has dual identities as pollutants and fertilizers. , it is fertilizer, and it can eliminate pollution. If it is not handled well, it will be a source of pollution and waste a lot of organic fertilizer resources. At present, the methods of manure treatment in farms mainly include the following: 1. All feces, urine and flushing water are stored for use in nearby farmland; 2. Feces, urine, and flushing water are used in hydraulic bi...
