Myriophyllum verticillatum, the whorl-leaf watermilfoil or whorled water-milfoil, is a native to much of North America, North Africa, and Eurasia. It closely resembles another native milfoil, called northern water milfoil (M. sibiricum) Whorled water milfoil is also easily confused with four types of invasive milfoils: Eurasian water milfoil (M. spicatum), Variable water-milfoil (M. heterophyllum), Parrot feather (M. aquaticum), and hybrid water milfoil (M. heterophyllum X M. laxum).

InactiveCN104556388ANormal growthPromote absorption and accumulationWater contaminantsBiological water/sewage treatmentMyriophyllumEnvironmental engineering
The invention discloses a method for promoting aquatic plants to remove heavy metals in sediments employing ultrasound. Through treatment disclosed by the invention, absorption accumulation of the aquatic plants (algae such as myriophyllum spicatum, hydrilla, hornwort and spirogyra) on heavy metals can be effectively promoted; and heavy metal concentration in water bodies and sediments is reduced. The treatment method is high in removal rate on heavy metals in the water bodies and sediments; the required ultrasound time is short; equipment is simple; the plants after being subjected to ultrasonic treatment can normally grow; secondary pollution to the environment is not caused; and the method disclosed by the invention belongs to an environment-friendly heavy metal repair processing technology.

System and method for purifying aquaculture wastewater
InactiveCN111762959AIncrease dissolved oxygen contentGuaranteed normal growthWater contaminantsWater aerationConstructed wetlandMyriophyllum
The invention relates to the technical field of wastewater treatment, in particular to a system and a method for purifying breeding wastewater. The invention provides a system for purifying aquaculture wastewater, which comprises an aeration tank, a front-end regulation and biological matrix treatment tank, a three-stage myriophyllum elatinoides constructed wetland and a subsurface infiltration deep treatment tank which are communicated in sequence. The aeration tank is used for improving the dissolved oxygen content of the aquaculture wastewater, so that sufficient oxygen is provided for aerobic microorganisms in the front-end regulation and biological matrix treatment tank; then, nitrogen and phosphorus are adsorbed and degraded through front-end adjustment and a biological matrix treatment pond, meanwhile, substances harmful to growth of myriophyllum elatinoides are intercepted, and normal growth of myriophyllum elatinoides is guaranteed; in the myriophyllum elatinoides constructedwetland, myriophyllum elatinoides is used for absorbing nitrogen and phosphorus in wastewater and adsorbing and enriching heavy metals and toxic and harmful substances at the same time; finally, residual pollutants are treated by the underflow percolation deep treatment tank to obtain effluent meeting the emission standard.

Aquatic-plant artificial turf and preparation method and application thereof
InactiveCN110304728ASimple methodSimple processHops/wine cultivationGrowth substratesPotamogeton crispusArtificial turf
The invention belongs to the technical field of water environment treatment, and particularly relates to aquatic-plant artificial turf and a preparation method and application thereof. The preparationmethod includes: adopting a lake shore zone soil and lake mud mixture as a fixation matrix and uncontaminated soil as a matrix for covering, and planting mixed seeds of potamogeton crispus clint, eelgrass, myriophyllum verticillatum and potamogeton pectinatus, wherein a proportion of lake shore zone soil and lake mud in the fixation matrix is 1-2:1. The artificial turf can sufficiently utilize water space resources and has good effect on improving water environment; the preparation method is easy to implement and simple in process.

Method and system for ecological management of rural domestic sewage
PendingCN107500484AInnovativeReduce construction costsTreatment involving filtrationMultistage water/sewage treatmentEnvironmental resource managementChemical oxygen demand
The invention relates to a method for ecological management of rural domestic sewage. The method includes that the domestic sewage of each household is collected to low-lying places of a residential area by the aid of a pipe network according to local conditions, a rural domestic sewage treatment system composing of a first-level grille tank, a third to sixth-level front adjustment and biological matrix purification tanks, a seventh to sixteenth-level myriophyllum elatinoides ecological wetlands and first to second-level terminal intensive treatment tanks is established. The pollutant content of COD (chemical oxygen demand), ammonia nitrogen and total phosphorus in discharged water in the terminal wetlands is controlled under the first-level control index value according to 'standards for urban living sewage discharge in the People's Republic of China' (GB18918-2002) issued and implemented by the state environmental protection administration in 2002; in addition, myriophyllum elatinoides harvested in the ecological wetlands is made into fodder to feed chickens, ducks, gooses, pigs, cows, sheep, fish and the like, and certain economic benefits are achieved.
