Treated water with good water quality which can be discharged or reused is obtained by efficiently removing SS, fluorine, cyanogen, selenium, ammonia, and COD components contained in coal gasification wastewater such as gas washing wastewater generated in a coal gasification step. A method of treating coal gasification wastewater comprising steps (1) to (4), wherein the step (1) is performed prior to the step (2): (1) a fluorine removal step in which fluorine is removed by coagulation sedimentation; (2) a cyanogen decomposition step in which cyanogen is decomposed by wet oxidation or thermal hydrolysis; (3) a selenium treatment step in which selenate ions are subjected to a reduction treatment with a metal reductant; and (4) a COD/ammonia removal step in which COD and/or ammonia are/is removed.

A water treatment system is provided including a disinfection system, a filter and a turbine generator. A manual pump is positioned downstream of the filter to create negative pressure to draw water through the filter. The manual pump also creates positive pressure to dispense treated water from the outlet of the system. The movement of the water through the system powers the turbine generator. The power generated can be used to monitor a characteristic of the water treatment system.

The invention provides a method for removing phenol-based substances from water by using an iron-sulfur supported multi-walled carbon nano-tube reinforced persulfate, and relates to a water treatment method. A purpose of the present invention is to solve the technical defects of high cost, poor removal effect and the like of the existing method for removing phenol-based substances from water. The method comprises: 1, mixing a persulfate and pre-treated water; 2, preparing iron-sulfur supported dual-phase composite multi-walled carbon nano-tubes; 3, pouring the iron-sulfur supported dual-phase composite multi-walled carbon nano-tubes; and 4, filtering the treated water so as to complete the method. With the method of the present invention, the removal rate of the phenol-based substances in the water can achieve 87-98%, and the residual phenol-based substance in the water can be removed.

The invention discloses a magnetic bioreaction separation device for treating organic wastewater, which comprises a magnetic bioreactor and a rare-earth magnetic disc separation device, wherein the magnetic bioreactor consists of a reaction vessel, and microbe carrier magnetic species or magnetic zooglea formed by the microbe carrier magnetic species, which is placed in the reaction vessel; the magnetic bioreactor is connected with the rare-earth magnetic disc separation device by a flowing discharge pipeline; and the upper part of the rare-earth magnetic disc separation device is provided with a water outlet pipe, and the lower part thereof is provided with a sludge discharge valve. Since the invention utilizes the microbes attached to the microbe carrier magnetic species or magnetic zooglea to decompose the organic matter, while the magnetic zooglea and the treated water can be treated by the rare-earth magnetic disc separation device for solid-liquid separation, not only the cost on the investment and operation is lower than that of the membrane bioreactor, but also the separation efficiency is high, the energy consumption is low, and the effect on denitrification, phosphorous, SS, COD and BOD removal; and the invention is particularly suitable for treating the organic wastewater with large flow and high concentration.

The self-operating device for the RV camp can self-generate and store electricity, and take water and storewater.

The invention relates to a disease-dried livestock and poultry drying wastewater treatment technology. The technology comprises the following steps: pumping wastewater generated in a drying process into a first reactor, adding a nonionic polyacrylamide reagent into the first reactor, performing uniform stirring, standing the obtained solution, pumping the obtained upper liquid into a rendering tank, and pumping the obtained lower liquid into a second reactor; adding an anionic polyacrylamide reagent and a cationic polyacrylamide reagent into the second reactor, performing uniform stirring, standing the obtained solution, pumping the obtained supernatant into a plate-and-frame filter press filled with polyacrylamide water-absorbent resin, and pumping the obtained lower floc into the rendering tank; and pumping a filtrate in the plate-and-frame filter press into a membrane module, detecting a clear liquid in the membrane module, directly discharging the qualified clear liquid, and pumping the above obtained concentrate into the second reactor. The technology has the advantages of simplicity in operation, low energy consumption, and strong applicability to the quality of water, and the treated water has low COD content and low ammonia nitrogen content.

The invention provides a dredging agent containing Anoxybacillusrupiensis. The dredging agent comprises a biocatalyst, a nonionic surfactant, an Adina rubella Hance root extract, an aloe extract, an eyebright extraction stock solution, a biological enzyme active agent, EDTA chelated iron, citric acid, protocatechuic acid, compound vitamin, a substrate, a porous sodium type activated zeolite powder carrier, halophilic bacteria, Anoxybacillusrupiensis, and an adhesive. The invention also provides application of the dredging agent containing Anoxybacillusrupiensis in a subsurface salt drainage pipe. The dredging agent provided by the invention has the following advantages: the alga-killing rate is improved and reaches 87 to 92%; good dredging effect is achieved; the quality of treated water is transparent and bright, has high transparency and is free of suspension; the quality of the water of a control group is yellowing and turbid, and contains black suspended solids with a concentration of 3 to 5%; and after dredging is completed, the salt water collection rate of the subsurface salt drainage pipe is improved and reaches 119.8 to 132.6%, while the salt water collection rate of the control group is 100%.

The invention discloses an environment-friendly type ecology reconstruction restoration method used for eutrophic water body. The environment-friendly type ecology reconstruction restoration method used for eutrophic water body comprises following steps: a first agent is uniformly sprayed into a water body for restoration so as to obtain a first treated water body; a second agent is uniformly sprayed into the first treated water body so as to obtain a second treated water body; gorgon Euryale is planted in the second treated water body in rows at a plantation coverage rate of 70%, and one month later, a third treated water body is obtained; the gorgon Euryale plantation coverage rate is controlled to be 50%, Hydrilla verticillata is planted between each paint of adjacent rows of gorgon Euryale at a plantation coverage rate of 20%, and one month later, a fourth treated water body is obtained; the gorgon Euryale plantation coverage rate is controlled to be 15%, more Hydrilla verticillatais planted between each paint of adjacent rows of gorgon Euryale to control the plantation coverage rate of Hydrilla verticillata to be 25%, and one month later, ecology reconstruction restoration isrealized.
