A new biological deodorization technology which is used in Tianjin Jizhuangzi Sewage Plant was introduced in this paper. The geographical position of Jizhuangzi Wastewater Treatment Plant is special. The plant has been surrounded by the living area. The problem of odor to people has been serious until a new deodorization technology is used. It is a source deodorization technology used special filler through vaccination, induction and catalytic to removed the malodorous sources. A special microbial incubator is used to culture and proliferate effective deodorant microorganisms on activated sludge sewage in the biological pool of the plant and then the sludge containing deodorant microbial reflowed to the wastewater inlet. The malodorous substances in the water are removed through adsorption, cohesion, biotransformation degradation and so on by the deodorant microbial. The case indicates that this technology is effective in practice and good for popularization. And this technology with simple process showed significant effect compared with other deodorant technologies and was more secure and convenient to build and run with low cost.

ABSTRAKPenelitian ini bertujuan untuk mengetahui pengelolaan LB3 yang telah dilakukan di indsutri tekstil. Metode penelitian menggunakan metode perbandingan antara kondisi di lapangan dengan peraturan yang berlaku. Berdasarkan hasil evaluasi mengenai pengelolaan LB3 yang dilakukan oleh PT X dapat disimpulkan beberapa hal yaitu sumber LB3 berasal dari proses produksi, lumpur IPAL, boiler, labolatorium, pemeliharaan mesin, dan klinik. Jenis LB3 yang dihasilkan berasal dari sumber spesifik umum yaitu lumpur IPAL dan limbah medis, sumber spesifik khusus yaitu hanya fly ash dan sumber tidak spesifik yang meliputi lampu TL, drum bekas LB3, oli bekas dan reagen. Karakteristik LB3 terdiri dari beracun, mudah menyala, korosif dan infeksius. PT X telah melakukan pengelolaan LB3 yang meliputi aspek pengemasan dan pewadahan, pengumpulan, penyimpanan, pengangkutan dokumen pengelolaan LB3, dan pelabelan LB3. Untuk kegiatan pengangkutan PT X bekerja sama dengan pihak ketiga diantaranya adalah PT Hijau Lestari, PT PPLI, PT Khalda, dan WGI. Berdasarkan hasil analisis pengelolaan LB3 di perusahaan ini termasuk kategori baik. Upaya pengelolaan LB3 yang harus ditingkatkan yaitu pada proses pelekatan simbol dan label, pengemasan, dan penyimpanan LB3.Kata Kunci: Kabupaten Bandung, Industri Tekstil, Limbah B3,ABSTRACTThis study aims to determine the management of LB3 that has been carried out in the textile industry. The research method uses a comparison between conditions in the field and applicable regulations Based on the evaluation results on the management of hazardous materials carried out by PT X, it can be concluded several things, namely the source of hazardous materials originating from the production process, sludge from the wastewater treatment plant, boilers, laboratory, engine maintenance, and clinics. The types of hazardous materials produced come from general specific sources such are sludge from the wastewater treatment plant and medical waste, specific sources which are fly ash and non-specific sources which include lamps, drums used in hazardous materials, used oil and reagents. The characteristics of hazardous materials consist of toxic, flammable, corrosive, and infectious. PT X has managed the management of hazardous materials which includes aspects of packaging, storage, collection, storage, transportation of documents on the management of hazardous materials, and labeling of hazardous materials. For transportation activities, PT X cooperates with third parties including PT Hijau Lestari, PT PPLI, PT Khalda, and WGI. Based on the analysis the achievement of the management of dangerous substances in this company including the good category. Efforts to manage toxic and hazardous materials must be improved in the process of sticking symbols and labels, packaging, and storing toxic and hazardous materials.Keywords: Bandung Regency, Testile iIndustry, hazardous waste materials

Most of the small wastewater treatment plants in Catalonia were not designed to remove nutrients. However, the large safety margins built into their original engineering design has meant that, in many cases, it has been possible to remove part of the nitrogen without being controlled. This paper focuses on the practical experience carried out in one of these facilities, the Bisbal wastewater treatment plant, aimed at enhancing the biological nitrogen removal using simple, low-cost, easy-to-operate measurement and control. The control strategy, which is based on air supply regulation, was previously designed using simulation studies. A dissolved oxygen monitoring system was installed into the facility, while nitrogen concentrations were analysed every day. Optimal dissolved oxygen profiles in the oxidation ditch were identified, while the air supply strategy was modified according to the variations in the influent.

Phosphorus is a non-renewable source and due to its high levels of phosphorus in water body may lead to eutrophication problems. It may come from many sources such as industry, agriculture and also from wastewater treatment plant. Large excessive of phosphorus may increase the purification cost and serious water quality problem because of the effect of algae toxin in water. Conventional wastewater treatment plant (WWTP) requires lot of cost such as labour, capital and maintenance costs. Therefore, the lab-scale aerated steel slag filter (ASSF) emerged as an alternative method to remove phosphorus from water due to its simple and also low cost technology has been developed to overcome this problem. This lab-scale filter has been conducted by using synthetic wastewater for an eight weeks starting from 19 March until 4th May 2014. This study is to investigate the effect of pH range from 4.5 to 7.5 and temperature for phosphorus removal mechanism. From this study, result shows that lab-scale ASSF achieve about 90% of phosphorus removal at pH 5.0. Based on X-ray fluorescence (XRF) analysis, the steel slag is rich in Ca, Al and Fe which is enhance the P removal with the influence of pH for precipitation mechanism process in this experiment.
