The invention relates to the purification of waste water drainage and can be used in water protection activities when additional amounts of clean water for irrigation and land reclamation.
A known method of purification of waste waters from pesticides (U.S. Pat. RU # 2060961, C02F 1/58, 27.05.1996). In this way, the wastewater from pesticides is carried out by introducing into the water activated carbon and defend.
The disadvantage of this method is uneven making in water active carbon, and, therefore, wastewater treatment. The low efficiency of the spray ground spray units and with aviation.
Known purification of drainage and wastewater (U.S. Pat. EN 2062634, B01D 36/04), being built on the open road drainage channel, consisting of a series of established settlers and sorption filters, made in the form of wells, equipped with removable mesh containers filled with sorbent. The disadvantage of this structure is the high cost of the used sorbent: modified claystone.
A known method of purification of drainage water and device for its implementation (U.S. Pat. RU # 2091538, EV 11/00, 27.09.1997). In this way the purification of drainage water by using mechanical retention of the impurities with the subsequent removal of residues of the dog is of icegov by passing the flow through the fibrous material.
The disadvantages of this method are the large work on the granulation of sapropel, the processing of fibrous filter material alumina, manufacture of the filter cartridge and the extraction of fibrous filter material.
The closest technical solution to the claimed is a method of purification of drainage water and device for its implementation (U.S. Pat. RU # 2401804, C02F 1/28, B01D 25/02, B01D 39/06, EV 11/00, C02F 103/10, 20.10.2010). In this way the removal of mechanical impurities, organic substances, heavy metals, and excess salts in the drainage discharge channel by passing the drainage flow through enshrined in the direction of the drainage-discharge channel filter matrix containing sorbents in the following sequence, taking into account their amount of sorbent in the filter matrix: shell - 50%, glauconitic sand - 30%, clay - 20%. The filter matrix is made in the form of a rigid metal frame made of steel area, bottom and side faces of which are covered with sheet steel. From the working party, providing the transmission of drainage flow, the frame is equipped with a trash bars. The framework contains three inserted removable cassette with sorbents that are located in sequence along the path of the drainage flow: limestone, glauconitic sand, Kera the zit. Each removable cartridge is a metal housing made of steel area, bottom and side faces of which are covered with sheet steel. The housing of the cassette is equipped with working parties brass mesh, attached to the inside of the fibrous filter material, and has on the perimeter of the two couplers in the form of strips of sheet steel that act as stiffeners, with mounting loops.
The disadvantages of this method are the large work on the production of matrix, its operation and handling.
The technical result of the invention is the cleaning of the drainage outflow from mechanical impurities and excess salts by passing it in the discharge channel through the sorbent (dried reeds and rushes), the amelioration of soils and ecology of rice fields by reducing sufoziya and removal of nutrients from the soil, reducing the cost and increasing the yield of rice.
The technical result is achieved by the fact that in the known method of purification of drainage water, including the transmission of drainage flow through the filter cartridge with a sorbent that is installed in the waste stream channel irrigation system according to the invention drainage flow is passed through a removable filter cartridge that is installed in the discharge channel of the rice irrigation system, and filling the percent sorbent, representing the dried plant cane and reeds, selected from weeds growing in said discharge channel, which is pre-sloped to the water level in the discharge channel during the transition of rice plants from one phase of vegetation to another, and replacement of the filter cartridge used for cleaning, also produced when the rice plants from one phase of vegetation to another.
The technical result is also achieved in that the device for implementing the method according to claim 1 made of custodyriyadh device integrally fixed in the waste stream channel rice irrigation system, the level of its installation is not less than the maximum water level in the discharge channel, while the said device has slots for mounting the filter cassette made of a hard metal frame with a fixed metal mesh, filled with dried plants grass with reeds and rushes.
The novelty of the claimed invention is caused by the wastewater through the filter cartridge, metal mesh which is completely filled beveled and dried plant cane and reeds used as sorbent.
Mowing weeds in the transition from one phase of the growing season of rice in another panel allows the manage water flow and water level in the discharge channel of the rice system, and, consequently, the position of the depression curve, which contributes to the saving of irrigation water and electricity, to improve the environmental situation in the rice irrigation system and increase rice yield. In addition, mowing can reduce percolation losses of irrigation water from rice cheque to reduce losses by transpiration.
Drying plant cane and reeds is to improve filtering through them and increase their resistance to the processes of decay that will allow you to clear the drainage flow.
With the passage of drainage water through the filter cartridge is cleaned from inside it mechanical impurities by their detention on the filter surface. Reduction of excess compounds of salts occurs at the expense of photoswest plant cane and reeds that will allow you to clear the drainage flow.
Use in the filtration matrix of dried plant cane and reeds contributes to the reduction in drainage outflow mechanical impurities and excess compounds, salts, reducing seepage outflow of irrigation water from rice cheque by creating an overpressure in the drainage channel of the inventive device, and, therefore, reduce irrigation water losses, reducing sufoziya and removal of nutrients from arable what about the horizon of the check. After replacing the filter cartridge plant cane and reeds, put on the rice fields, thereby enriching the soil with organic substances, and improving drainage condition of the soil.
The invention is illustrated: figure 1 is a fragment of the waste channel, 2 - section a-a waste channel.
A device for cleaning the drainage flow includes custodierimus device 4 with grooves 5 (Fig 1), integrally installed in line drainage-discharge channel [bottom discharge channel - 1, the slope of the discharge channel 2, the maximum water level in the discharge channel - 3 (1, 2)], and a removable filter cartridge 6 (1, 2)made of hard metal frame 7 (figure 2), with a fixed metal mesh 8 (figure 2), with a metal mesh filter cartridge is completely filled with sorbent 9 (2), as which use dried plant cane and reeds.
The method is carried out using the device as follows.
Since the beginning of the growing season of rice is used to supply water from the dispenser on the rice fields, accompanied by the outflow seepage from checks in the discharge channels and re-using them for checks flooding. In line with waste channel 1,3 (figure 1) integrally fixed custodierimus device 4 (figure 1) with grooves 5 (Fig 1) for filter cartridges 6 (1, 2). And tentative is but in the discharge channel cut weeds to the level of the water and leave it for drying. After drying choose plants reeds and rushes and completely fill them mesh 8 (2) of the filter cartridge 6 (figure 2), which is established in custodierimus device 4 (figure 2), than reduce the outflow of water filtration and purified drainage flow from within him of mechanical impurities and excess compounds salts. While mowing, and replacing the filter cartridge 6 is carried out by moving the rice plants from one phase of vegetation to another.
