| 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(jìn)集水池，達(dá)一定液位時(shí)，攪拌器與潛污泵自動(dòng)啟動(dòng)，污水經(jīng)管道進(jìn)入經(jīng)過(guò)四個(gè)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(yù)處理-固液分離 Pre-treatment：通過(guò)固體分離將糞渣擠壓脫水成固體,還田利用。糞水進(jìn)入沼氣池，沼氣用于發(fā)電，沼液作為肥料資源利用，多余的進(jìn)入工業(yè)模式，提供生產(chǎn)用水再循環(huán)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(guò)數(shù)以億計(jì)氣泡張力作用分離糞水中的懸浮物；分離開(kāi)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(guó)家排放標(biāo)準(zhǔn)。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(tuán)，在疊螺機(jī)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(jī)。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(fù)合膜,將氣浮后污水進(jìn)行層層過(guò)濾,去除其中的重金屬、細(xì)菌、色素、SS、部分氨氮,使出水水質(zhì)清澈見(jiàn)底,可用于豬舍沖欄,綠化灌溉,水產(chǎn)養(yǎng)殖,真正實(shí)現(xiàn)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(chǎng)空氣凈化系統(tǒng)
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.
