C) recovery of fast-growing waterplant and post-processed
Detect the body eutrophication threshold concentration, when threshold concentration: when total phosphorus TP≤0.02mg/L and total nitrogen TN≤0.2mg/L, will cultivate the unit salvaging and deliver to the bank by boats and ships, scaffold and container are disassembled; And container is sent to biogas plant, feed factory or vegetable chemistry extraction plant together with culture medium and fast-growing waterplant as raw material focuses on, scaffold is reclaimed, be used for again carrying container, recycle;
Described scaffold is folding umbrella, and its center is disk, and disc circumference is provided with several poles;
Described container is located at respectively on center disk and the several pole, and container is the vegetable material establishment;
Described fast-growing waterplant is floating plant, mainly contains Herba Eichhorniae, mater convolvulus, water peanut, water lily, Herba Eichhorniae, Da Piao, floating heart, frogbit, field word duckweed.Herba Eichhorniae, mater convolvulus, water peanut etc.
The embodiment of the invention:
A) the fast-growing waterplant is cultivated the making of unit: consult Fig. 1, the making that described fast-growing waterplant is cultivated the unit is comprised of a scaffold 1, several containers 2, some substratum and waterplant matter, culture medium is divided in several containers, container 2 is distributed on the scaffold 1, and the fast-growing water plant planting is in the culture medium of container 2; Described scaffold 1 is that a center is provided with disk 11 and the peripheral umbrella folding frame that is provided with several poles 12, and disk 11 and pole 12 are provided with the container permanent seat; Container 2 is worked out by bamboo cane, wicker, reed or stalk material.Container 2 is located at respectively on the container permanent seat of center disk and several poles; The culture medium that dry branches and fallen leaves, plant ash, plant compost mix is housed in the container 2; Select Herba Eichhorniae, mater convolvulus, water peanut constant speed natural disposition water plant planting in the culture medium of container 2.
B) placement of fast-growing waterplant: because the distribution of each region threshold concentration of water body is different, certain waters is divided into A district, B district and C district, A district threshold concentration by the body eutrophication threshold concentration that detects: total phosphorus TP=0.02mg/L, total nitrogen TN=0.4mg/L; B district threshold concentration: total phosphorus TP=0.05mg/L, total nitrogen TN=0.2mg/L; C district threshold concentration: total phosphorus TP=0.05mg/L, total nitrogen TN=0.4mg/L; According to the detected value of each region threshold concentration, implement the placement that the fast-growing waterplant is cultivated the unit, a scaffold 1 is a cultivation unit, the density of setting in A district is: 300/hectare; The density of setting in B district is: 400/hectare; The density of setting in C district is: 800/hectare;
