A distinctive feature of waste water of fi sh processing enterprises is the high content of organic substances: COD - 620-3500 mg/L, BOD-220-2860 mg/L. The ratio of BOD:COD=0.68-0.83 in the waste water of fi sh processing enterprises shows a high potential for the use of biological treatment methods. Further study requires the removal of biogenic elements, because, for example, for a fi sh cannery, the ratio of BOD:N:P=100:3.79:1.08 and 100:4.77:0.57. This article presents the experience of design, construction, start-up and adjustment of sewage treatment facilities of a fi sh processing enterprise. For wastewater treatment, the following scheme was developed and manufactured by the ECOLOS company: a receiving well with a basket, a drum grate, a horizontal grease trap, an homogenizer, a reagent pressure fl otation unit, a membrane bioreactor, and ultraviolet disinfection. The quality of waste water at the outlet of the treatment facilities meets the requirements of the Normative- permissible discharge provided by LLC «Russkaya Treska».

The large part of the Russian Federation locates in arctic and subarctic climatic zones, which determine the specificity of design, construction and operation of sewage systems of these regions. Nowadays, the most part of small Arctic towns has no wastewater treatment facilities, while the available biological treatment facilities do not work properly. An alternative way is physicochemical treatment, which is more resistant to severe climate and volley wastewater discharge than biological treatment. The paper presents the research results of total change the biological into physicochemical treatment. The main stages of such a treatment include coagulation, filtration, oxidation and two-stage filtration (mechanical and absorption). The experiments show a 90.8% decrease in the concentration of chemical oxygen and a 74% and 82.5% decrease in nitrates and ammonium.

Sewage treatment remains a delicate subject and requires technical improvements to increase the efficiency of the systems responsible for the treatment. Numerical simulations are also a very useful tool, especially if they are used during the design phase. Thus, the paper aims to present the results obtained by CFD numerical simulations in the case of an important element within an existing wastewater treatment plant, namely the waste water treatment well, thus obtaining constructive solutions of a better functionally to the designed version. Through these, the work demonstrates the necessity of analyzes with CFD methods during design of the main elements of hydrotechnical constructions, but also the necessity of adjusting the numerical models with results obtained from experiments, measurements. The results show that the modifications described in the paper would bring significant improvements in waste disposal.

The biological treatment method is widely used in Lithuania due to its high efficiency, low cost and suitability for treating various types of wastewater. After technological processes various mineral substances, such as chlorides and sulphates, get into water bodies. These substances are not removed from wastewater by the biological treatment method. The purpose of this study is to determine the concentrations of chlorides and sulphates, investigate the influence of enzyme preparations upon quality and energy consumption and assess energy changes in the trophic food chain during biological treatment. To analyse the mineral salt influence of the biooxidation process a series of laboratory tests was carried out: biochemical oxygen consumption (BOD), activated sludge concentration and other indexes. It is found experimentally that a 400 mg/1 concentration of chlorides disarranges the activity of microorganisms, and at a 700 mg/1 concentration active sludge is no longer suitable for biological treatment. Also, we investigated the effect of a ferment preparation “Roebic” on effluence of sewage treatment. In a tank with an enzyme the total amount of energy after treatment increases by 5–30 %. It is determined by calculating the accumulation of energy in an active‐sludge system that an enzyme preparation increases the energy levels of the system.

The performance of isolated designed consortia comprisingBacillus pumilus, Brevibacterium sp, and Pseudomonas aeruginosafor the treatment of sewage wastewater in terms of reduction in COD (chemical oxygen demand), BOD (biochemical oxygen demand) MLSS (mixed liquor suspended solids), and TSS (total suspended solids) was studied. Different parameters were optimized (inoculum size, agitation, and temperature) to achieve effective results in less period of time. The results obtained indicated that consortium in the ratio of 1 : 2 (effluent : biomass) at 200 rpm, 35°C is capable of effectively reducing the pollutional load of the sewage wastewaters, in terms of COD, BOD, TSS, and MLSS within the desired discharge limits, that is, 32 mg/L, 8 mg/L, 162 mg/L, and 190 mg/L. The use of such specific consortia can overcome the inefficiencies of the conventional biological treatment facilities currently operational in sewage treatment plants.

A mathematical model is presented, consisting of a two-layer, finite difference hydrodynamic submodel and a compartmental water quality sub-model. The model is calibrated with field data. Then, it is applied to Southern Evoikos Gulf, an open coastal water body of particular ecological significance in the region of Attiki, in Greece. The application of the model aims at assessing the effect of three alternative treatment scenarios (i.e. biological treatment, biological treatment with N removal and biological treatment with N and P removal) performed in four sewage treatment plants (of a total capacity of 1,000,000 equivalent population) on the water quality of the Gulf. The calculations show that N is the limiting nutrient and its removal results in an improvement of the quality of the recipient, whereas the additional implementation of P removal has a rather limited impact.

Guangxi rural contiguous environmental governance project was started in April 2011, with 88 sets of sewage treatment facilities, 22 sets of household garbage collection treatment facilities. The finishing of 74 sets of sewage treatment facilities, and 19 sets of life garbage collection treatment facilities revealed that this project start-up was basically normal. According to the situation of the contiguous rural environmental governance project in Lijiang River basin and the Red River Valley, it shows that the scale of rural sewage treatment facilities is generally small—the average scale is 107.2 m3/d, the average price of unit construction investment ( including pipeline construction ) is 6445 Yuan/m3, and the main treatment process is the bio-contact oxidation method + constructed wetland; the average price of unit construction investment on rural garbage disposal is 339.2 thousands of Yuan, garbage collection and clearance are the main processes, meanwhile the urban and rural garbage integration treatment mode — “household classification - village collection - township transfer - county treatment” is only carried out in the regions of nearby towns and convenient transportation.
