環保處理系統Environment Protection System
打造了生態養殖環境
DEXING has spent heavily building up an ecological environment of breeding
| 德興污水處理采用兩道系統模式：在各養豬場因地制宜的配套了不同工藝的環保處理設施，實現糞污資源利用和水資源循環利用的有機配合。第一方案，糞污無害化處理和資源化利用。采用主體工藝為：固體分離還田利用>黑膜沼氣池+沼氣發電>沼液暫存池>沼液ER均質池>還田利用，實現資源化利用。第二方案，工業化污水處理循環利用。采用主體工藝為：固體分離還田利用>氣浮裝置>疊螺離干機>動態好氧池+沉淀>反滲透水處理系統，實現水資源循環再利用。 | 公司以實施農牧結合，種養結合“四位一體”循環農業生態經濟生產方式.以沼氣為紐帶建立起多個物種共棲，智能多級利用的物質循環利用型生態農業模式。實現豬場廢棄物無害化處理，糞污資源化循環利用，最終實現零排放。真正走生態健康養殖之路，保障農村公共衛生環境，達到良好的社會與環境效益。 |
| There are 2 distinctive systems used in DEXING for sewage disposal: in deferent farms of DEXING, different environmental protection approaches are adopted for 2 objectives, manure recycling and water recycling. Solution no. 1, manure processed and recycled to be fertilizer for clops use. Solution no. 2, the sewage is treated by going through different techniques including air flotation, stacking and dehydrating, after going through the last step of reverse osmosis, the water is as clear as it can be used in pen cleaning, greening irrigation and aquaculture. | DEXING combines agriculture with animal husbandry, planting and breeding, the “FOUR IN ONE”, a pattern of recycling agricultural eco-economic mode of production. It realizes Hazard-free treatment of waste, manure recycling,ultimately achieves zero emissions. The path of healthy ecological farming gives the rural public a healthy and fresh environment, which are set as the industry benchmark by the provincial authorities. |
處理工序 Steps：糞水引進集水池，達一定液位時，攪拌器與潛污泵自動啟動，污水經管道進入經過四個階段的處理工序。The fecal sewage is collected, the mixer and submersible pump starts as per set, going through 4 steps.
① 預處理-固液分離 Pre-treatment：通過固體分離將糞渣擠壓脫水成固體,還田利用。糞水進入沼氣池，沼氣用于發電，沼液作為肥料資源利用，多余的進入工業模式，提供生產用水再循環利用。Solid-liquid separation] Separating fecal in from the liquid, dehydrate into solid fecal to be used in farming. The remaining liquid enters the methane tank, to generate biogas. The biogas slurry is then recycled for farming. The extra is fed into the air floating process, to realize the water filtration and recycling purpose.
②氣浮工藝-固液深度分離 Air flotation：通過數以億計氣泡張力作用分離糞水中的懸浮物；分離開的黑色懸濁液體，在PAC&PAM的共同作用下，將水中的固體懸浮小顆粒SS撇出，使其降到國家排放標準。In-depth Solid-liquid separation] The suspended solids in manure are separated by functioning tension of hundreds of millions of bubbles; With the help of PAC&PAM, the suspending small particles SS is then removed from the black sewage. The remaining water meets national emission standards.
③氣浮疊螺工藝-污泥脫水 Stacking Sludge dehydrating：氣浮后污泥含水量在96%-99%之間。在PAM的作用下，污泥中的SS絮凝成團，在疊螺機的作用下被擠壓螺旋增壓呈餅狀（含水率70-80%）排出，利用還田，擠出的水重新注入氣浮機。The percentage of water of the sludge after flotation is between 96% and 99%. With the function of PAM, the SS flocculation clusters. The stacking machine squeezes the water out and turn it into cake-shape (containing 70-80% water), used as fertilizer, the extrude-water is re-injected into the air flotation process.
④反滲透-清水交付 Reverse osmosis-Clear water result：利用超分子納米復合膜,將氣浮后污水進行層層過濾,去除其中的重金屬、細菌、色素、SS、部分氨氮,使出水水質清澈見底,可用于豬舍沖欄,綠化灌溉,水產養殖,真正實現零排放！With the use of supramolecular nanocomposite membrane, the sewage goes through layers of filtration after air flotation, while the heavy metals, bacteria, pigments, SS, part of the ammonia nitrogen are removed afterwards, so that the water is crystal clear, which can be used for pig pen cleansing, green irrigation and aquaculture, actually achieving zero emissions!
豬場空氣凈化系統
Airwasher System
The modular air purifying system consists of 3 steps. The exhaust-gas will be collected and go through the buffer washing zone, the microbial filtration system and the processed-water monitoring system, from which the exhaust-gas is cleaned and purified, fresh and friendly to the environment.
