Low-carbon improved biological trickling filter

Abstract

The invention discloses a low-carbon improved biological trickling filter. The low-carbon improved biological trickling filter is characterized in that a filter comprises at least three branch filters, the branch filters are respectively arranged at different altitudes, and automatic air supplementing sections with preset heights are formed among the various branch filters; packing is arranged in the various branch filters, the branch filters comprise perforated sieve plates on the tops of the branch filters and perforated sieve plates at the bottoms of the branch filters, and the branch packing is arranged among the perforated sieve plates on the tops of the branch filters and the perforated sieve plates at the bottoms of the branch filters; the low-carbon improved biological trickling filter further a plurality of ventilating pipes, the ventilating pipes are inserted in the branch packing, and air can be led into the branch packing by the ventilating pipes. The low-carbon improved biological trickling filter has the advantages that each branch packing can be supported by the corresponding perforated sieve plates at the upper end and the lower end of the corresponding branch filter and accordingly is convenient to replace; oxygen can be timely supplemented to the branch packing by the ventilating pipes inserted in the branch packing, accordingly, the activity of biological membranes on the branch packing can be guaranteed, the types of the branch packing can be pertinently selected according to sewage treatment requirements of sites, and sewage treatment effects can be improved.

Description

technical field [0001] The invention relates to a trickling filter structure, in particular to a low-carbon improved biological trickling filter. Background technique [0002] Catering wastewater has a high content of organic matter, including various food fibers, starch, fat, animal and vegetable oils and detergents. At present, the environmental protection departments in various places have intensified their management of the catering industry, requiring restaurants in many places to install grease traps. Difficulties. However, some small restaurants and farmhouse catering industries in remote areas emit direct emissions, which have brought serious impacts on the surrounding environment. [0003] Due to its scattered distribution and large fluctuations in water quality and water volume, the commonly used ecological treatment technologies, such as stabilization ponds, artificial wetlands and some common technologies used in sewage treatment plants, are relatively expensiv...

Problems solved by technology

However, there are the following deficiencies in the actual application process: first, the packing is easy to block, and the biofilm falling off in the reactor will easily cause the gap between the packing to become smaller and smaller, and even lead to blockage, resulting in the failure of the effluent to meet the standard and difficulty in replacing the packing; The reason is that the oxygen supply required for the degradation of organic matter in the filter is insufficient, resulting in insufficient activity of the biofilm on the filler, and the treatment effect is not good, causing the effluent to fail to meet the standard; the third is that the effect of nitrogen and phosphorus removal is not ideal
