Pink reineckea herbs are planted in pollution environments of livestock and poultry breeding biogas slurry, absorption effect of the pink reineckea herbs on NH4+-N, troponin (TN), total protein (TP), chemical oxygen demand (CODcr) and other pollutants in the livestock and poultry breeding biogas slurry and characteristics of the pink reineckea herbs of being tenacious in life force, capable of being directly planted, free of special management and perennial are made the best of so as to permanently solve the pollution problem of the livestock and poultry breeding biogas slurry. The application has the advantages of being small in investment, low in operation cost, good in effect, easy and simple to operate and capable of ensuring purifying effect of an artificial wetland system in winter. The harvested pink reineckea herbs can cure phthisis, coughing haemoptysis, chronic bronchitis, asthma, rheumatic arthritis and other symptoms. By adopting the pink reineckea herbs to treat waste water, environment protection is combined with landscape construction and economic construction, the sustainable development concept with consideration of sewage treatment, ecological restoration, landscape construction and economic benefit is reflected, and therefore the application is profound in meaning.

Fiber separation type equipment
ActiveCN110924209AGreat suctionTo achieve the purpose of purifying wastewaterPulp liquor regenerationPulp beating methodsFiberWater storage
The invention discloses fiber separation type equipment and belongs to the field of paper fiber recovery. The fiber separation type equipment comprises a fixed base, a fiber separation box is fixedlyconnected to the top of the fixed base, supporting plates are fixedly mounted at the tops of a left inner wall and a right inner wall of the fiber separation box, a separation screen pipe is rotatablyconnected between the two supporting plates, and a left side and a right side of the separation screen pipe extend to the sides, opposite to each other, of the two supporting plates correspondingly.According to the scheme, a water suction pump at the bottom penetrates through a water storage filter tank and extends to the bottom of a filter screen layer, therefore, the water pump can pump a filtered water source, one end, away from a water inlet pump, of a water pumping pipe at a top is fixedly connected and communicated with the fiber separation box, therefore, the water source filtered inthe water storage filter tank can be reutilized through the water inlet pump and injected into the fiber separation tank, the impurity separation effect of the equipment is relatively good, the energywaste caused by repeated recycling is reduced, and the equipment has the advantage of wastewater recycling capacity.

Application of polygonum capitatum in purifying livestock breeding biogas slurry
InactiveCN102583756BReduce contentImprove purification effectSustainable biological treatmentBiological water/sewage treatmentUpper urinary tract infectionZephyranthes candida
The invention discloses application of polygonum capitatum in purifying livestock breeding biogas slurry, which belongs to the field of wastewater processing. The polygonum capitatum is planted in a livestock breeding biogas slurry pollution environment; and the function of the polygonum capitatum for absorbing pollution matters such as NH4+-N, TN, TP, CODcr in the livestock breeding biogas slurry, and the characteristics that the polygonum capitatum has tenacious vitality, can be planted directly, has no need to be managed specially, and is perennial are fully utilized, so that the problem of livestock breeding biogas slurry pollution is solved permanently. The investment is small, the operation cost is low, the effect is good, the operation is simple and easy to realize, and the purifying effect of an artificial wetland system in winter is ensured. The harvested polygonum capitatum can be used medicinally, and can be used for treating urinary tract infection, nephropyelitis and the like. The zephyranthes candida is utilized for processing wastewater, and the environment protection is combined with pharmaceutical plant cultivation, so that a sustainable development idea taking consideration of sewage processing, ecological restoration and economic construction is embodied, and the characteristic of combing theory research and practical application is realized.
